Adding a time stamp to a point feature when GPS is not available
I need a way of automatically adding a time stamp to a point feature, much like you would add a waypoint to a map. We do wireless (cell, WiFi) surveys and Global Mapper is part of my GIS toolbox. Our test equipment works great outdoors when GPS is available. The problem is indoors, it would be nice to open a floor plan in Global Mapper, and then place points on the plan that corresponds to places we took measurements. If we can associate a time with that point then we can cross reference it with the time that the test instrument took measurements. Any thoughts on how to do this in Global Mapper? Thanks!
