Sorry, I was more concern on the values for the horizontal shift that I omitted a lot of useful information. Projection Projection Type: Lambert Conformal Conic 2 Parallel False Northing: 1000000 sft False Easting: 3000000 sft Origin Latitude: 39°20'00.00000 N Origin Longitude 105°30'00.00000 W Parallel 1: 40°47'00.0000N Parallel 2: 39°43'00.0000 Semi major Axis: 20925604.474 sft Flattening: 298.2572 Project Elevation: 7500 ft And the typical values in the local grid look something like this: Y=364,046.135 X=1,359,194.067 Z=6348.177 How/where do I apply the shift values when creating the prj? Thank you for the video links.

I would like to create a .prj file in order to exchange data between CAD and GIS. For references, I have 9 ground control points in both the local grid and SPCS NAD83 equivalent and a table with the following values from the surveyor. Projection Type: Lambert Conformal Conic 2 Parallel False Northing: 1000000 usft False Easting: 3000000 usft Horizontal Adjustment Type: Plane Origin Northing: 1347119.328 usft Origin Easting: 2338925.736 usft Translation North -1000000.629 usft Translation East: -999854.751 usft Rotation: -0°00'21.046132 Scale Factor: 1.000323 Reading some of the articles, I am going through a bit of information overload. I am looking for a method to develop the .prj for this scenario in particular. Thank you, David
