[gdal-dev] Detecting SPARSE rasters

[Jon Morris]

We usually use the SPARSE_OK option when creating GTiffs, but as a lot of our clients use ArcGIS, we need to ensure that the sparse option is not used for client deliverables. After a tiff has been created though, it's not easy to tell whether it is sparse or not. Is there an easy way of detecting which rasters are sparse and therefore cannot be sent to clients?

Using tiffinfo -D test.tif seems to give an error message like "TIFFFillTile: 0: Invalid tile byte count, tile 0." , so I've been using this to check, but is there a better way?

Or have Esri started supporting sparse rasters, and if so, does anyone know which version of ArcMap 10.x? (Our clients are mostly on older versions, not sure if any are using Pro yet).

Thanks,

Jon
