Rasterbasemaps
Raster basemaps are georeferenced raster layers used as the base map in geographic information systems and web mapping applications. They provide background imagery or relief to give geographic context for overlaid vector features or other data.
Raster basemaps are typically composed of uniform grid cells (pixels) arranged in a coordinate reference system
Common sources include satellite imagery, aerial photography, and derived products such as hillshade or elevation-derived rasters.
In practice, raster basemaps must align with the map's coordinate system and projection. Resampling methods (nearest
Limitations include large file sizes, storage and bandwidth requirements, and potential licensing restrictions. Raster basemaps are
