After I export .NET to .shp, I open the .shp file in ArcGIS or QGIS. The file doesn't have any coordinate. It's just a link and node "diagram". I can not project it or do any processing because lack of latitude and longitude.
Do you know how to fix it?
We simply take a *.prj file that uses the same coordinates as the node and link file (usually a state plane in feet) and copy/rename it to the same name as the shapefile. You have to do this for each shape file.
