Details of layer for creating raster tiles.

Parameters:

  • id (str) – the id of the source layer to rasterise

  • extent (tuple(south, west, north, east)) – the extent of the base map in which the layer is to be reasterised as decimal latitude and longitude coordinates.

  • map_source (MapSource) – the source of the layer’s data

  • min_zoom – The minimum zoom level to generate tiles for. Optional, defaults to MIN_ZOOM

  • local_world_to_base (Transform) – an optional transform from the raster layer’s local world coordinates to the base map’s world coordinates. Defaults to None, meaning the Identity() transform
