I am trying to convert northing/easting coordinates from Michigan Geo-Ref (m) to Michigan State Plane International (ft). I followed a helpful guide (below), which helped me do this conversion.

After switching projections in ArcCat. it was time to calculate geometry for my northing and easting fields. So as the guide said I followed these instructions.

In the Calculate Geometry dialog select these options:

a. Property: X Coordinate of Point

b. Coordinate System: Use coordinate system of the data frame (in which will be listed your Michigan North system)

c. Units: meters (IN MY CASE FT)

Then click OK.

After doing so all of my attributes switched to the same value (i.e., northings of 20587707.37 and eastings of 26246789.6853).

What am I doing wrong here? Is there a way that I can run this differently to produce different values?

Thanks for your help,

Mike

I figured it out. ESRI does not have the same projection file for Michigan GeoRef as the State of Michigan (survey data) giving me error. Additional error came in when I chose to use "Calculate Geometry", which does not calculate international feet, only US feet when using my chosen projection.

Thanks for your help and continued interest today.
