Since: ArcGIS Maps SDK for JavaScript 4.28
OverviewAn Oriented Imagery Layer is a single spatial layer that can be created from a Feature Service; or ArcGIS Online or ArcGIS Enterprise portal items.
Oriented Imagery layers are composed of discrete features (or camera locations), each of which has a Geometry that allows it to be rendered in either a 2D MapView or 3D SceneView as a graphic with spatial context. These features also contain data attributes that provide additional information about the real-world feature it represents; attributes may be viewed in popup windows and used for rendering the layer.
The layer fetches the imagery data once you select a point on the map. It uses a custom BestImage logic to determine the most accurate image for a selected point and display it in the viewer widget.
OrientedImageryLayers may be queried, analyzed, and rendered to visualize data in a spatial context.
Creating an OrientedImageryLayerOrientedImageryLayers may be created in one of two ways: from a service URL or an ArcGIS portal item ID.
Reference a service URLTo create an OrientedImageryLayer instance from a service, you must set the url property to the REST endpoint of a layer in a Feature Service. For a layer to be visible in a view, it must be added to the Map referenced by the view. See Map.add() for information about adding layers to a map.
const OrientedImageryLayer = await $arcgis.import("@arcgis/core/layers/OrientedImageryLayer.js");
const layer = new OrientedImageryLayer({
url: "url-to-oriented-imagery-service"
});
map.add(layer); // adds the layer to the map
You can also create an OrientedImageryLayer from its ID if it exists as an item in ArcGIS Online or ArcGIS Enterprise. For example, the following snippet shows how to add a new OrientedImageryLayer instance to a map using the portalItem property.
// points to a hosted Feature Layer with Oriented Imagery Layer as a sub layer in ArcGIS Online
const layer = new OrientedImageryLayer({
portalItem: { // autocasts as esri/portal/PortalItem
id: "2c65c47b75654a078038abae52c58f70"
}
});
map.add(layer); // adds the layer to the map

Property Details blendMode String
Blend modes are used to blend layers together to create an interesting effect in a layer, or even to produce what seems like a new layer. Unlike the method of using transparency which can result in a washed-out top layer, blend modes can create a variety of very vibrant and intriguing results by blending a layer with the layer(s) below it.
When blending layers, a top layer is a layer that has a blend mode applied. All layers underneath the top layer are background layers. The default blending mode is normal where the top layer is simply displayed over the background layer. While this default behavior is perfectly acceptable, the use of blend modes on layers open up a world of endless possibilities to generate creative maps.
The layers in a GroupLayer are blended together in isolation from the rest of the map.
In the following screenshots, the vintage shaded relief layer is displayed over a firefly world imagery layer. The color blend mode is applied to the vintage shaded relief and the result looks like a new layer.
The following factors will affect the blend result:
average blend mode is often similar to the effect of setting the layer's opacity to 50%.
Lighten blend modes:
The following blend modes create lighter results than all layers. In lighten blend modes, pure black colors in the top layer become transparent allowing the background layer to show through. White in the top layer will stay unchanged. Any color that is lighter than pure black is going to lighten colors in the top layer to varying degrees all way to pure white.
Lighten blend modes can be useful when lightening dark colors of the top layer or removing black colors from the result. The plus, lighten and screen modes can be used to brighten layers that have faded or dark colors on a dark background.
darken blend mode. lighter Colors in top and background layers are multiplied by their alphas (layer opacity and layer's data opacity. Then the resulting colors are added together. All overlapping midrange colors are lightened in the top layer. The opacity of layer and layer's data will affect the blend result. plus Colors in top and background layers are added together. All overlapping midrange colors are lightened in the top layer. This mode is also known as add or linear-dodge. screen Multiplies inverted colors in top and background layers then inverts the colors again. The resulting colors will be lighter than the original color with less contrast. Screen can produce many different levels of brightening depending on the luminosity values of the top layer. Can be thought of as the opposite of the multiply mode. color-dodge Divides colors in background layer by the inverted top layer. This lightens the background layer depending on the value of the top layer. The brighter the top layer, the more its color affects the background layer. Decreases the contrast between top and background layers resulting in saturated mid-tones and blown highlights.
Darken blend modes:
The following blend modes create darker results than all layers. In darken blend modes, pure white in the top layer will become transparent allowing the background layer to show through. Black in the top layer will stay unchanged. Any color that is darker than pure white is going to darken a top layer to varying degrees all the way to pure black.
The multiply blend mode is often used to highlight shadows, show contrast, or accentuate an aspect of a map. For example, you can use multiply blend mode on a topographic map displayed over hillshade when you want to have your elevation show through the topographic layer. See the intro to layer blending sample.
The multiply and darken modes can be used to have dark labels of the basemap to show through top layers. See the darken blending sample.
The color-burn mode works well with colorful top and background layers since it increases saturation in mid-tones. It increases the contrast by tinting pixels in overlapping areas in top and bottom layers more towards the top layer color. Use this blend mode, when you want an effect with more contrast than multiply or darken.
The following screenshots show how the multiply blend mode used for creating a physical map of the world that shows both boundaries and elevation.
Contrast blend modes:
The following blend modes create contrast by both lightening the lighter areas and darkening the darker areas in the top layer by using lightening or darkening blend modes to create the blend. The contrast blend modes will lighten the colors lighter than 50% gray ([128,128,128]), and darken the colors darker than 50% gray. 50% gray will be transparent in the top layer. Each mode can create a variety of results depending on the colors of top and background layers being blended together. The overlay blend mode makes its calculations based on the brightness of the colors in the background layer while all of the other contrast blend modes make their calculations based on the brightness of the top layer. Some of these modes are designed to simulate the effect of shining a light through the top layer, effectively projecting upon the layers beneath it.
Contrast blend modes can be used to increase the contrast and saturation to have more vibrant colors and give a punch to your layers. For example, you can duplicate a layer and set overlay blend mode on the top layer to increase the contrast and tones of your layer. You can also add a polygon layer with a white fill symbol over a dark imagery layer and apply soft-light blend mode to increase the brightness in the imagery layer.
The following screenshots show an effect of the overlay blend mode on a GraphicsLayer. The left image shows when the buffer graphics layer has the normal blend mode. As you can see, the gray color for the buffer polygon is blocking the intersecting census tracts. The right image shows when the overlay blend mode is applied to the buffer graphics layer. The overlay blend mode darkens or lightens the gray buffer polygon depending on the colors of the background layer while the census tracts layer is shining through. See this in action.
multiply and screen modes to darken and lighten colors in the top layer with the background layer always shining through. The result is darker color values in the background layer intensify the top layer, while lighter colors in the background layer wash out overlapping areas in the top layer. soft-light Applies a half strength screen mode to lighter areas and half strength multiply mode to darken areas of the top layer. You can think of the soft-light as a softer version of the overlay mode. hard-light Multiplies or screens the colors, depending on colors of the top layer. The effect is similar to shining a harsh spotlight on the top layer. vivid-light Uses a combination of color-burn or color-dodge by increasing or decreasing the contrast, depending on colors in the top layer.
Component blend modes:
The following blend modes use primary color components, which are hue, saturation and luminosity to blend top and background layers. You can add a feature layer with a simple renderer over any layer and set hue, saturation, color or luminosity blend mode on this layer. With this technique, you create a brand new looking map.
The following screenshots show where the topo layer is blended with world hillshade layer with luminosity blend mode. The result is a drastically different looking map which preserves the brightness of the topo layer while adapting the hue and saturation of the hillshade layer.
color blend mode. color Creates an effect with the hue and saturation of the top layer and the luminosity of the background layer. Can be thought of as the opposite of luminosity blend mode.
Composite blend modes:
The following blend modes can be used to mask the contents of top, background or both layers.
Destination modes are used to mask the data of the top layer with the data of the background layer.Source modes are used to mask the data of the background layer with the data of the top layer.The destination-in blend mode can be used to show areas of focus such as earthquakes, animal migration, or point-source pollution by revealing the underlying map, providing a bird's eye view of the phenomenon. Check out multiple blending and groupLayer blending samples to see composite blend modes in action.
The following screenshots show feature and imagery layers on the left side on their own in the order they are drawn in the view. The imagery layer that contains land cover classification rasters. The feature layer contains 2007 county crops data. The right image shows the result of layer blending where destination-in blendMode is set on the imagery layer. As you can see, the effect is very different from the original layers. The blended result shows areas of cultivated crops only (where both imagery and feature layers overlap).
Invert blend modes:
The following blend modes either invert or cancel out colors depending on colors of the background layer. These blend modes look for variations between top and background layers. For example, you can use difference or exclusion blend modes on two imagery layers of forest covers to visualize how forest covers changed from one year to another.
The invert blend mode can be used to turn any light basemap into a dark basemap to accommodate those who work in low-light conditions. The following screenshots show how setting the invert blend mode set on a feature layer with a simple renderer turns the world terrain basemap into a dark themed basemap in no time.
difference blend mode, except that the resulting image is lighter overall. Overlapping areas with lighter color values are lightened, while darker overlapping color values become transparent. minus Subtracts colors of the top layer from colors of the background layer making the blend result darker. In the case of negative values, black is displayed. invert Inverts the background colors wherever the top and background layers overlap. The invert blend mode inverts the layer similar to a photographic negative. reflect This blend mode creates effects as if you added shiny objects or areas of light in the layer. Black pixels in the background layer are ignored as if they were transparent.

Camera orientation defining the first rotation around z-axis of the camera. Defined in degrees. Heading values are measured in the positive clockwise direction where north is defined as 0 degrees. -999 is used when the orientation is unknown.
Example
// point images without cameraHeading to north using camera heading
layer.cameraHeading = 90;The height of camera above the ground when the imagery was captured. The units are in meters. Camera height is used to determine the visible extent of the image, large values will result in a greater view extent. Values should not be less than 0.
Example
// Adds value to images without a cameraHeight
layer.cameraHeight = 100;Camera orientation defining the second rotation around x-axis of the camera in the positive counterclockwise direction. Defined in degrees. The pitch is 0 degrees when the camera is facing straight down to ground. The valid range of pitch value is from 0 to 180 degrees, with 180 degrees for a camera facing straight up and 90 degrees for a camera facing horizon.
Example
// Adds pitch value to images without a cameraPitch
layer.cameraPitch = 90;Camera orientation defining the final rotation around z-axis of the camera in the positive clockwise direction. The camera housing rotation is defined in degrees. Valid values range from -90 to +90.

Modifies the extent of the image's ground footprint. The ground footprint of each image is computed to search for images that contain the selected location, which is identified as the red cross on the map. Valid values are from -50 to 50. Negative percentage values shrink the size of the ground footprint and positive values increase the size of the ground footprint.
Example
// Adds a coveragePercent value to image footprint

Property declaredClass Stringreadonly
The name of the class. The declared class name is formatted as esri.folder.className.
Since: ArcGIS Maps SDK for JavaScript 4.29 OrientedImageryLayer since 4.28, definitionExpression added at 4.29.
The SQL where clause used to filter features on the client. Only the features that satisfy the definition expression are displayed in the View. Setting a definition expression is useful when the dataset is large and you don't want to bring all features to the client for analysis. Definition expressions may be set when a layer is constructed prior to it loading in the view or after it has been added to the map. If the definition expression is set after the layer has been added to the map, the view will automatically refresh itself to display the features that satisfy the new definition expression.

Suffix used to build the depth image url path in conjunction with the depth image attribute.
Since: ArcGIS Maps SDK for JavaScript 4.29 OrientedImageryLayer since 4.28, displayField added at 4.29.
The name of the layer's primary display field. The value of this property matches the name of one of the fields of the layer.
displayFilterEnabled Boolean
Since: ArcGIS Maps SDK for JavaScript 4.32 OrientedImageryLayer since 4.28, displayFilterEnabled added at 4.32.
Indicates whether the layer's displayFilterInfo is applied when rendering the layer in the view. If false, the layer's display filter is ignored and all features are rendered without filtering. To ignore display filters across all layers in the view, set the view's displayFilterEnabled property to false.
Since: ArcGIS Maps SDK for JavaScript 4.32 OrientedImageryLayer since 4.28, displayFilterInfo added at 4.32.
Information related to a display filter associated with a layer. Display filters control which features are visible on the map. They allow you to display a subset of features while retaining access to all features for querying and analysis. Unlike definitionExpression, which filters data at the source level, display filters only affect visibility on the map. Therefore display filters should be ignored when querying data to present to users. Display filters can be disabled for all layers in the map by setting the view's displayFilterEnabled property to false.
To optimize memory usage for rendering, display filters may be appended to the definitionExpression when querying the service. As a result, the filtered features may not be available on the client for executing layer view queries. To determine if all features are available in the view, check the layer view's hasAllFeaturesInView property when layer view's dataUpdating is false. If false, the layer view does not have all features in the view and you should query the layer instead.
Example
// set a scale-dependent display filter on a layer
const layer = new FeatureLayer({
portalItem: {
id: "28dbd58ad90e4a47ab0e0334d2b69427"
},
minScale: 0,
maxScale: 0,
outFields: ["*"],
// set scale-dependent display filters to declutter the display at different scales.
// Show more streams as user zooms in and less as user zooms out.
displayFilterInfo: new DisplayFilterInfo({
mode: "scale",
filters: [
{

});Effect provides various filter functions that can be performed on the layer to achieve different visual effects similar to how image filters work. This powerful capability allows you to apply css filter-like functions to layers to create custom visual effects to enhance the cartographic quality of your maps. This is done by applying the desired effect to the layer's effect property as a string or an array of objects to set scale dependent effects.

];Since: ArcGIS Maps SDK for JavaScript 4.31 OrientedImageryLayer since 4.28, elevationInfo added at 4.31.
Specifies how features are placed on the vertical axis (z). This property may only be used in a SceneView. See the ElevationInfo sample for an example of how this property may be used.
If the elevation info is not specified, the effective elevation depends on the context and could vary per graphic.
Defines how the feature is placed with respect to the terrain surface or 3D objects in the scene. If the geometry consists of multiple points (e.g. lines or polygons), the elevation is evaluated separately for each point. See the table below for a list of possible values.
Mode Description on-the-ground Features are aligned to the Ground. If the scene contains an IntegratedMeshLayer or IntegratedMesh3DTilesLayer, then features are aligned to the IntegratedMeshLayer or IntegratedMesh3DTilesLayer. If features have z-values, then the z-values are ignored in this mode. Features with 2D symbols are draped on the Ground or IntegratedMeshLayer or IntegratedMesh3DTilesLayer. This is the default mode for layers without z-values containing Polyline, Polygon features or Point features rendered with ObjectSymbol3DLayer. absolute-height Features are placed at an absolute elevation (z-value) above sea level. This z-value is determined by the geometry's z-value (if present). IffeatureExpressionInfo is defined, the result of the expression is used instead of the geometry's z-value. This mode doesn't take the elevation of the Ground or any other layers into account. This is the default value of features with any geometry type where hasZ is true. relative-to-ground Features are placed at an elevation relative to the Ground or IntegratedMeshLayer or IntegratedMesh3DTilesLayer. The feature's elevation is determined by summing up the elevation of the Ground or IntegratedMeshLayer or IntegratedMesh3DTilesLayer and the geometry's z-value (if present). If featureExpressionInfo is defined, the result of the expression is used instead of the geometry's z-value. If the geometries don't have z-values, relative-to-ground is the default value for Point geometries rendered with IconSymbol3DLayers. relative-to-scene Features are aligned to extruded polygons, meshes, 3D Object SceneLayers or BuildingSceneLayers, depending on which one has higher elevation. If the feature is not directly above a building or any other feature, it is aligned to the elevation of the Ground or the IntegratedMeshLayer or IntegratedMesh3DTilesLayer. If present, the geometry's z-value is added to the elevation. If featureExpressionInfo is defined, the result of the expression is used instead of the geometry's z-value.
Possible Values:"on-the-ground"|"relative-to-ground"|"absolute-height"|"relative-to-scene"
offset Number|null|undefinedAn elevation offset, which is added to the vertical position of the feature. If unit is not defined, the offset is in meters. When mode = "on-the-ground", this property has no effect.
Defines how to override a feature's Z-value based on its attributes.
Title of the expression.
expression StringAn Arcade expression following the specification defined by the Arcade Feature Z Profile. Expressions may reference field values using the $feature profile variable and must return a number representing the z-value of the feature. When mode = "on-the-ground", this property has no effect. For line and polygon geometries the result of the expression is the same for all vertices of a feature.
The unit for featureExpressionInfo and offset values.
The source of elevation, that will be used to compute ground to image transformations. The elevation source can be a digital elevation model (DEM) or a constant value. A tile image service can be used as the digital elevation model. The unit of constant elevation value should be in meters.
The farthest usable distance of the imagery from the camera position. FarDistance is used to determine the extent of the image footprint, which is used to determine if an image is returned when you click on the map, and for creating optional footprint features. The units are in meters. Far distance should be always greater than 0.
Example
// Adds farDistance value to features without it
layer.farDistance = 60;The featureEffect can be used to draw attention features of interest. It allows for the selection of features via a filter, and an includedEffect and excludedEffect are applied to those features that respectively pass or fail the filter requirements.
Notes
featureEffect is set on the layer, it will be inherited by layerView.featureEffect unless the developer overrides it on the layer view. The layerView.featureEffect will take precedence over layer.featureEffect if both properties are set.featureEffect, effect, opacity and blendMode.Examples
// gray out features that fall outside of the 3 mile buffer of the mouse's location
// by setting feature effect on excluded features
layer.featureEffect = new FeatureEffect({
filter: new FeatureFilter({
geometry: filterGeometry,
spatialRelationship: "intersects",
distance: 3,
units: "miles"
}),
excludedEffect: "grayscale(100%) opacity(30%)"
});// Apply a drop-shadow feature effect to the features that intersect the borough boundaries,
// while applying blur and brightness effects to the features that are excluded from filter criteria.
// The resulting map will make it easier to spot if the residents are more likely to experience deprivation
// if they live on a borough boundary.
const featureFilter = new FeatureFilter({
where: "BoroughEdge='true'"
});
layer.featureEffect = new FeatureEffect({
filter: featureFilter,
includedEffect: "drop-shadow(3px, 3px, 3px, black)",
excludedEffect: "blur(1px) brightness(65%)"
});Configures the method for reducing the number of features in the view. By default this property is null, which indicates the layer view should draw every feature.
There are three types of feature reduction: selection, cluster, and binning.
Examples
// clusters features based on their spatial proximity to other features
layer.featureReduction = {
type: "cluster",
clusterRadius: 100

};Since: ArcGIS Maps SDK for JavaScript 4.29 OrientedImageryLayer since 4.28, fields added at 4.29.
An array of fields in the layer. Each field represents an attribute that may contain a value for each feature in the layer. For example, a field named POP_2015, stores information about total population as a numeric value for each feature; this value represents the total number of people living within the geographic bounds of the feature.
The full extent of the layer. By default, this is worldwide. This property may be used to set the extent of the view to match a layer's extent so that its features appear to fill the view. See the sample snippet below.
Example
// Once the layer loads, set the view's extent to the layer's fullextent
layer.when(function(){
view.extent = layer.fullExtent;
}); geometryType String

Property loaded Booleanreadonly
Indicates whether the layer's resources have loaded. When true, all the properties of the object can be accessed.
maxScale Number
The maximum scale (most zoomed in) at which the layer is visible in the view. If the map is zoomed in beyond this scale, the layer will not be visible. A value of 0 means the layer does not have a maximum scale. The maxScale value should always be smaller than the minScale value, and greater than or equal to the service specification.
Examples
// The layer will not be visible when the view is zoomed in beyond a scale of 1:1,000
layer.maxScale = 1000;// The layer's visibility is not restricted to a maximum scale.
layer.maxScale = 0;Maximum search distance to be used while querying the feature service specified in the Oriented Imagery Layer. The maximum distance can never be less than zero.
Example
layer.maximumDistance = 100; minScale Number
The minimum scale (most zoomed out) at which the layer is visible in the view. If the map is zoomed out beyond this scale, the layer will not be visible. A value of 0 means the layer does not have a minimum scale. The minScale value should always be larger than the maxScale value, and lesser than or equal to the service specification.
Examples
// The layer will not be visible when the view is zoomed out beyond a scale of 1:3,000,000
layer.minScale = 3000000;// The layer's visibility is not restricted to a minimum scale.

Semicolon-delimited string used to store standard deviation values. The standard deviation values are in the following order and format: Camera location in XY direction; camera height; camera heading; camera pitch; camera roll; near distance; far distance; elevation (all in meters).
String that defines the imagery type used in the particular Oriented Imagery Layer. Valid values: 360, horizontal, inspection, nadir, oblique.
Possible Values:"horizontal" |"nadir" |"oblique" |"360" |"inspection" |"terrestrial-frame-video" |"aerial-frame-video" |"terrestrial-360-video" |"aerial-360-video"
Example
layer.orientedImageryType = "oblique";Since: ArcGIS Maps SDK for JavaScript 4.29 OrientedImageryLayer since 4.28, outFields added at 4.29.
An array of field names to include in the OrientedImageryLayer. If not specified, the layer will include all fields.
The parent to which the layer belongs.
persistenceEnabled Boolean
popupEnabled Boolean
Since: ArcGIS Maps SDK for JavaScript 4.29 OrientedImageryLayer since 4.28, popupEnabled added at 4.29.
Indicates whether to display popups when features in the layer are clicked. The layer needs to have a popupTemplate to define what information should be displayed in the popup. Alternatively, a default popup template may be automatically used if Popup.defaultPopupTemplateEnabled is set to true.
Since: ArcGIS Maps SDK for JavaScript 4.29 OrientedImageryLayer since 4.28, popupTemplate added at 4.29.
The popup template for the layer. When set on the layer, the popupTemplate allows users to access attributes and display their values in the view's Popup when a feature is selected using text and/or charts. See the PopupTemplate sample for an example of how PopupTemplate interacts with a FeatureLayer.
A default popup template is automatically used if no popupTemplate has been defined when Popup.defaultPopupTemplateEnabled is set to true.
Since: ArcGIS Maps SDK for JavaScript 4.29 OrientedImageryLayer since 4.28, portalItem added at 4.29.
The portal item referencing the Oriented Imagery layer item from which the OrientedImageryLayer is loaded.
Since: ArcGIS Maps SDK for JavaScript 4.29 OrientedImageryLayer since 4.28, renderer added at 4.29.
The renderer assigned to the layer. The renderer defines how to visualize each feature in the layer. Depending on the renderer type, features may be visualized with the same symbol, or with varying symbols based on the values of provided attribute fields or functions.
Since: ArcGIS Maps SDK for JavaScript 4.29 OrientedImageryLayer since 4.28, spatialReference added at 4.29.
The spatial reference of the layer. The default value is WGS84. This property can be set explicitly to project the longitude and latitude coordinates when the OrientedImageryLayer is loaded. While not required, explicitly setting the spatial reference of the layer will improve the performance when projecting to a spatial reference other than the one used by the coordinates in the raw data.
timeIntervalUnit String
Defines the unit of time used in the viewer's time selector tool. Images will be filtered in the viewer based on the Time Unit value defined here. Valid values: days, hours, minutes, months, weeks, years
Possible Values:"days" |"hours" |"minutes" |"months" |"weeks" |"years"
Example
layer.verticalFieldOfView = 20;The title of the layer used to identify it in places such as the LayerList widget.
If the layer is loaded from a portal item, the title of the portal item will be used. If a layer is loaded as part of a webmap or a webscene, then the title of the layer as stored in the webmap/webscene will be used.
Inherited
Property type Stringreadonly
The layer type provides a convenient way to check the type of the layer without the need to import specific layer modules.
For OrientedImageryLayer the type is always "oriented-imagery".
Inherited
Property uid Stringreadonly
Since: ArcGIS Maps SDK for JavaScript 4.33 Layer since 4.0, uid added at 4.33.
An automatically generated unique identifier assigned to the instance. The unique id is generated each time the application is loaded.
Since: ArcGIS Maps SDK for JavaScript 4.29 OrientedImageryLayer since 4.28, url added at 4.29.
The URL of the Oriented Imagery layer service.
Example
// Pass the service url to create an Oriented Imagery layer.
const layer = new OrientedImageryLayer({
url: "url-to-oriented-imagery-service"
});
map.add(layer); // adds the layer to the map
});The camera's scope in the vertical direction. The units are in degrees and valid values range from 0 to 180.
Example
layer.verticalFieldOfView = 20;Defines the primary unit to be used for all vertical measurements. Valid values: feet, meter.
Possible Values:"feet" |"meter"
Example
layer.verticalMeasurementUnit = "meter";Prefix used to build the video url path in conjunction with the image attribute.
Suffix used to build the video url path in conjunction with the image attribute.
Since: ArcGIS Maps SDK for JavaScript 4.30 Layer since 4.0, visibilityTimeExtent added at 4.30.
Specifies a fixed time extent during which a layer should be visible. This property can be used to configure a layer that does not have time values stored in an attribute field to work with time. Once configured, the TimeSlider widget will display the layer within the set time extent. In the case that only one of the start or end date values are available, the layer remains visible indefinitely in the direction where there is no time value.
Aerial imagery can capture seasonal variations in vegetation, water bodies, and land use patterns. For example, in agricultural regions, aerial imageries taken during different growing seasons provide insights into crop health and productivity. Defining a fixed time extent on imageries from specific time periods provides temporal context and facilitates focused analysis based on specific time periods or events.
Inherited
Property visible Boolean
Indicates if the layer is visible in the View. When false, the layer may still be added to a Map instance that is referenced in a view, but its features will not be visible in the view.
Example
// The layer is no longer visible in the view
layer.visible = false;
// Watch for changes in the layer's visibility
// and set the visibility of another layer when it changes
reactiveUtils.watch(
() => layer.visible,
(visible) => {
if (visible) {
anotherLayer.visible = true;
} else {
anotherLayer.visible = false;
}
}
