I just want to start out by saying I know a little bit about cad but I do not know a whole lot about plotting corrdinates. My issue is as follows. I have about 40 gps corrdinates that I took with Droid2Cad which are recorded as lat, long, and alt. The points can be exported to .dxf and .kml(google earth). I have exported them to both and it looks like google earth plots them correct but I have issues with the .dxf file. I have a .dwg site plan of an agriculture site from a engineering firm that seems to be drawn at 1:1. When I go to overlay the points on the site plan the points end up way off off the site plan. I dont know if I need to scale the .dxf or what. The points seem to be in the right configuration but they dont land anywhere close to the right spots. When I overlayed the points on the .dwg, I selected all the points, copied with a base point on a point that I knew the corresponding point on the .dwg, and pasted that point to the point on the .dwg. I dont know if I did a good enough job explaining this but I would appreciate any help anyone can give me. If you need more info or clarification please let me know. Thank you for your time.
