CAD tip # 12914:

Download the VLX file of this LISP add-on application from Download and load it into your AutoCAD, Map or Civil with the command APPLOAD. Make sure your DWG drawing has some geodetic coordinate system assigned (see the command _GEOGRAPHICLOCATION).

Then you can use the command GEO2GPS to display GPS coordinates of the clicked points or the command GEO2UTM to display UTM coordinates. In addition, the Label option creates a label in the drawing with the GPS or UTM coordinate value. The Dynamic option switches to a mode where the GPS/UTM coordinate is dynamically displayed as a tooltip when the mouse is moved. Click to insert a label, press "C" to change tooltip color, press "G" to switch back to individual get-points, "X" or Enter exits the loop.

The GEOMARKPOISTIONSIZE variable controls the size of the coordinate label in the drawing.

Or use the command GEO2MAPS to display the map of neighborhood of a given point in Google Maps, GEO2MAPSV to display Street View of the picked view, or GEO2MAPY to display the map in the Czech web service Mapy.cz.

See examples:

The LISP function (geo2gps _clicked_coordinate_) returns the GPS coordinate of the specified point.

Set:

(setq GEO2GPSURLSUFFIX "xxx")

to add suffix to web maps URLs (e.g. zoom level, type of map, etc).
