Raster Tiles API



The Raster Tiles API serves raster tiles from NextBillion.ai raster tilesets. Raster data refers to pixel-based data format in which data is stored in a grid structure. Each pixel, or unit of information, has the same size and shape, but varies in value. Raster Tiles are images created in raster data format. These tiles can be used to display maps as a grid of images which can be loaded on map-based tools or platforms.
