Document rasterproxy file format #129

Closed drwelby closed 3 years ago

drwelby commented 3 years ago

It appears the rasterproxy file format shares a similar format to the MRF metadata file, but could you share a schema or some example files to compare against?

abhiataero commented 3 years ago

@drwelby Raster proxy and MRF have same structure, there are two major difference

  1. The raster proxy has a source node which points to the location of the source data
  2. The raster proxy has data and index node which tell you the location where the data will be stored locally for caching

The Raster proxy is called as Caching MRF if it is pointing to any raster other than MRF The Raster proxy is called as Clone MRF if it is pointing to MRF raster format

more information on this can be found in this link

Thanks for the clarification, using the Caching MRF as a starting point I was able to generate working Raster Proxies with GDAL.
