[gdal-dev] Combine aerial images

[Frank Broniewski]

Hi,

I have a directory with appr. 2800 aerial images, each 1kmx1km. I'm 
using this source for a Mapserver WMS layer. Unfortunately the amount of 
data to process is way too much for a Mapserver WMS service.

Now I want to create larger overview images where the aerial images are 
combined together. The route I wanted to was

1) build a VRT from the images
2) use gdal_translate to get a new geotiff with a smaller size (pixel wise)


Is this a valid route to go?

Many thanks,

Frank
