[mapserver-users] Image Pyramid with gdal_retile and two UTM zones

[Fawcett, David (MPCA)]

The problem is that both images are showing up in the same UTM Zone. A quick glance at the gdal_retile.py doc page indicates that all of the input tiles need to be in the same spatial reference system.

I assume that you could reproject one of your tiles into the adjacent UTM Zone and then run gdal_retile, but I don't know if that would cause any distortion.  

David.

Subject: [mapserver-users] Image Pyramid with gdal_retile and two UTM zones

Hello. I have a large raster mosaic and it is currently split into two zones.
UTM 10N and UTM 11N (Northern and Southern California). Currently, when I
use gdal_retile, the two zones sit next to each other. Is there some way I
can tile things so that the zones are on top of each other, and the state
looks complete?
