I plan to convert a
.dwg-file to QGIS. The coordinate system of the
.dwg-file is set up in feet in the x and y directions from a point near the bottom center of the drawing. This coordinate system makes it easy to measure the size and distances between the various features in the drawing.
But after converting to QGIS, I would like to add latitude and longitude coordinates to the QGIS file so that the various features in the drawing can be located on the ground using a GPS app on a cell phone.
How can I add GPS coordinates to the QGIS file without having to give up the existing coordinate system in feet?
