[Mapserver-users] Projection Help

[Paul VanDyke]

Thanks for your quick reply.

The original jpeg does not have any info associated with it.  It was
just a satellite photo I found on the 'net and saved to my hard disk.
It is totally unrectified.  

I've rectfied it myself by using the georeferencing toolbar in ArcMap.
It allows you to manipulate the raster image to make it fit your map.

The raster data and shapefile do meet up fine in ArcMap


Here is the output from gdalinfo:
