[gdal-dev] Question of file ordering in VRT

[Stephen Woodbridge]

Hi all,

When I have multiple overlapping files in VRT which pixel takes 
president? I'm assuming that the later files in the VRT would be the one 
presented. For example, I have multiple satellite images with names like 
YYYYMMDDHHMM-.....tif so when I use

gdalbuiltvrt YYYYMMDD.vrt YYYYMMDD*.tif

and then view that, in say mapserver, am I seeing the newest images or 
the oldest image when 2+ images overlap in any given area?

Thanks,
   -Steve
