Forgive me, I’m a CAD person, and am very new to GIS. I’ve searched google and this site extensively for an answer, with no luck.
My problem is that I was given a large number of sistered Raster files; a TIFF and an accompanying .tfw file. The XY coordinates in the .tfw file are given in feet.
I’ve got these images to come in perfectly in CAD by setting the coordinates to UTM83-15 and manually declaring the input coordinates to be feet. It lines up perfectly.
However, when I try to use ArcMap, if I set the zone to UTM83 Zone 15N, it seems to force (logically so, I suppose) the input to be read as meters, which pushes everything ~3.28x up and to the right of where I want it.
I cannot for the life of me find a way to force it to be in feet, nor can I find the same coord system not in metric. Im about to write a script to go through and convert all the X-Y to meteres: an imperfect solution as I don’t really want to manipulate my base data.
To fix this:
- Is there a way to force ArcMap to read an input file as feet while using a UTM 15 origin?
- Is there a foot based surrogate coordinate system with the same origin for UTM83-15N?
