I have two world files that are associated with two different .pngs that
should be very far apart, 50,000 meters according to the world files,
but MapServer is rendering them one just a few meters apart, does anyone
know why this might be?
World file 1:
4.553027622068700
0.000000000000000

World file 2:

Here is the pgrinfo command on the shapefile that was created, as you
can see the extent only covers a small area
> ogrinfo -al -so moc_pds_test.shp
