Description

When dealing with rasters in a web context, rasters might be read from remote binary sources or are returned to the user as files. In such situations, the rasters would have to be written to disk as a file and then openend with GDALRaster. This can represent significant overhead.

GDAL has an internal memory based virtual file system that allows reading and writing file buffers to memory and treat them as files. Allowing GDALRasters to use that filesystem would be useful for using rasters in web requests.
