Terradue/DotNetStac: .Net library for working with any SpatioTemporal Asset Catalog (STAC)

DotNetStac helps you to work with STAC (catalog, collection, item)

In a nutshell, the library allows serialization/desrialization of STAC JSON documents (using Newtonsoft.JSON) to typed object modeling STAC objects with properties represented in enhanced objects such as geometries, time stamp/period/span, numerical values and many more via STAC extension plugins engine. Stac Item object is based on GeoJSON.Net feature.

• (De)Serialization engine fully compliant with current version of STAC specifications
• Many helpers to support STAC objects manipulation:
  • Field accessors using class properties and common metadata (e.g. Title, DateTime, Geometry)
  • Collection creation helper summarizing Items set
• JSON Schema validation using Json.NET Schema
• STAC extensions support with C# extension classes with direct accessors to the fields:
  • Electro-Optical with Common Band Name enumeration
  • File Info with helpers to calculate multihash checksum
  • Processing
  • Projection with helpers to set epsg id and wkt2 representation from Proj.Net Coordinate Systems
  • Raster
  • SAR with helpers for interferometric searches
  • Satellite with extra orbit state vector and baseline calculation
  • Scientific Citation
  • View Geometry

$ dotnet add package DotNetStac

using Stac;
using Stac.Schemas;
using System;
using System.Net;
using Newtonsoft.Json.Schema;

var webc = new WebClient();
Uri catalogUri = new Uri("https://raw.githubusercontent.com/radiantearth/stac-spec/master/examples/catalog.json");
StacValidator stacValidator = new StacValidator(new JSchemaUrlResolver());

// StacConvert.Deserialize is the helper to start loading any STAC document
var json = webc.DownloadString(catalogUri);
bool valid = stacValidator.ValidateJson(json);
StacCatalog catalog = StacConvert.Deserialize<StacCatalog>(json);

Console.Out.WriteLine(catalog.Id + ": " + catalog.Description + (valid ? " [VALID]" : "[INVALID]"));
Console.Out.WriteLine(catalog.StacVersion);

A dedicated notebook is available to get started with all DotNetStac features. If you want to play directly with the notebook, you can
