I was wondering if anyone knows where to find grid files (*.lat, *.lon) for all NYC local borough coordinate systems.
I have a survey in AutoCAD, in NYS planes long island coordinates and I have to tranform it into Staten Island local coordinates. While I can manually tranfer the linework with a lisp routine, I need to add in GIS data, thus I need grid files for the transform. I'm going to have the same problem with a project in Queens.
I have asked the borough presidents offices, the DCP and DoITT, but have gotten nowhere.
