i dont have problems to calculate the scale of an image, because im using one
of mapserver apps, fusion to show the map and it has widgets do display the
scale of a zoom in/out, or i just use map.scaledenom to show the current
scale. My problem is how to find the scale where i should create the ne

Sorry to bother again, when i use gdal_merge.py the part -ps 160 160, thats
the pixel dimension and i get an image 1kb. The pixel size of the original
file is 0.08 meters. So i think i should use 0.08x32 in the gdal_merge.py
command? And how many tiles should i merge together? Now i have 2T images
Thanx to you my questions are comming to an end [?]

Should i retile the new mosaiced overview? Meaning should i create smaller

My only problem now is to find the correct scale for each layer

One simple trick that I don't think has been mentioned is to add the shape
indexes of each of your raster layers to your mapfile to be able to see how
many raster tiles were used for each request. This makes it clear how many
files were used to create your output image.

Edi,
Generally speaking, as long as you enable internal tiling when bu
