Public Functions Detailed Description
A tile matrix set is a set of tile matrices and some common parameters of a layer in an Open Geospatial Consortium (OGC) Web Map Tile Service (WMTS).
A WmtsTileMatrixSet (also referred to as a "tiling scheme") may be obtained from the service info of a loaded wmts service.
A WmtsTileMatrixSet is composed of one or more predefined tile matrices for a series of fixed scales. As the scale descreases (see WmtsTileMatrix::scaleDenominator), the number of tiles in the matrix increases - each tile being of a smaller geographic area and of a higher resolution.
A WmtsTileMatrixSet is defined in a specific spatialReference and covers a defined extent.
Example: List the tile matrix sets for a service:
QList<WmtsLayer*> lyrs;
// enumerate the WmtsTileMatrixSet for each WmtsLayerInfo in the WmtsServiceInfo
WmtsServiceInfo serviceInfo = wmtsService->serviceInfo();
QList<WmtsLayerInfo> layerInfos = serviceInfo.layerInfos();
for (const WmtsLayerInfo& layerInfo : layerInfos)
{
qDebug() << layerInfo.wmtsLayerId();
QList<WmtsTileMatrixSet> tileMatrixSets = layerInfo.tileMatrixSets();
for (const WmtsTileMatrixSet& tileMatrixSet : tileMatrixSets)
{
qDebug() << tileMatrixSet.title();
// create the WmtsLayer for this tile matrix set
auto* lyr = new WmtsLayer(serviceUrl, layerInfo.wmtsLayerId(), tileMatrixSet.id(), parent);
lyrs.append(lyr);
// List the tile matrices available at each scale
QList<WmtsTileMatrix> matrices = tileMatrixSet.tileMatrices();
for (const WmtsTileMatrix& matrix : matrices)
{
qDebug() << matrix.id() << matrix.scaleDenominator();
}
}
}
