Raster Store Detail

GET /api/rstores/{slug}/

Request an individual raster with a provided slug. A slug is a URL friendly name of a resource in the API. Each climate dataset or resource has its own unique slug. A resource slug is generally composed of {variable}_{period}_{model}_{scenario}_{timestep}.

Response fields include image (raster file link), event (date), and units (unit of measurement for pixel values). Image statistics for min and max with regard to the nodata value, and dimensions xpixsize ypixsize. Map tiles can be requested with the url template at tileurl.
