[gdal-dev] Can VRT be used to control display order of images in mosaic?

[Roger André]

Hi All,

I'd like to control the order in which overlapping images are displayed in a
mosaic.  Is it possible to do that by using a VRT, and altering the order in
which the files are defined in it?

The online doc for gdalbuildvrt states, "If there is some amount of spatial
overlapping between files, the order may depend on the order they are
inserted in the VRT file, but this behaviour should not be relied on."

Not sure if this disclaimer is for the gdalbuildvrt utility, or describes
the generic behavior of a raster VRT.

Thanks,

Roger
