The IGeometryProcessor is used to process geometry features from vector tiles.
VectorTileDecoder will pass to this interface implementation sequences of geometries projected in webMercator local tile space (coordinates relative to tile's north-east corner). If desired, the world positions can be converted to GeoCoordinates using the Projection.unprojectPoint, for example:
convert(geometry: ILineGeometry): GeoCoordinates[] { const projection = webMercatorTilingScheme.projection; const coordinates = geometry.positions.map(worldP => projection.unprojectPoint(worldP)); return coordinates; }The methods of concrete implementations of IGeometryProcessor are called to process point, line and polygon geometries, see VectorTileDecoder.
