[gdal-dev] Re: How to generate tiles with multiple vrt's using GDAL

[Vaish]

 Hi,
   How can I generate tiles using multiple VRT'S without any tranparent gaps 
 using gdal commands.
 
 1. When I run the gdal2tiles command on the first VRT , it works well but 
when I run gdal2tiles command on the second VRT and point to the same outfput
 folder. The tiles are overwritten.
 
 I do not want to merge files because it takes time . Need to do this for an
 ongoing project. So everyday I can make VRT's , generate tiles and append to 
 same output folder.
 
 Can anyone suggest a soloution to the above problem?
 
 Thanks,
 Vaish
