Entering data from a GPS


Recommended Posts

Currently, we do not support GPS definitions for survey information. I have added this to the wish list already.

To enter in inforamtion, you can use an x, y and z value for points to generate the DTM. You can also draw 3d polygons based on x, y and z values to generate a DTM.

VW does not support long/lat coordinates (or 'map projections,' for that matter). Conversion to long/lat to x/y is not exactly easy, since there are dozens of map projection systems (all more or less inaccurate since a spherical surface cannot be accurately represented with a plane.) Your best bet is, unfortunately, to use a GIS program such as MapInfo as 'middleware' and convert long/lat data into the x/y projection your base maps / surveys use.

There may be some hope in the wish list item: many years ago, Diehl Graphsoft had a mapping program called Azimuth (???), so NNA is in possession of the required core technology.
