I am trying to create a Local projection in US Survey Feet.

I have pulled out the parameters from Trimble Buisness Center ...

I have no experiance with creating a .prj so if you guys can help I would greatly appreciate it.

Hi guys

I am wanting to use a custom .prj file

This .prj file is based in feet and State plane coordinates.  I notice when I choose the .prj file and upload it In the reference Pane the Tabs change from Lat and Long to north and East Tabs.... thats perfect

However on the reference tabs it  reads as Northing(m)  Easting(m) Altitude (m)

This makes me think that photoscan is not recognizing the fact the .prj file is in feet. Is there anyway to confirm that photoscan is actually in feet as opposed to meters.

is it possible to measure in imperial units as opposed to metric?

any help is appreciated.
