Converting Measuring Units

exploretheworld

I converted the units to feet in the projection for everything in the map I downloaded from USGS Seamless on Global Mapper including the file with set of points I'm using to obtain elevations for those points. I used the Export Vector Data option and I was able to get a file with the set of coordinates I loaded and elevations. However, the elevations don't match with what they are suppose to be. They all seem to be over 3X less than the correct elevations I'm suppose to get. Is there a conversion of units I might have missed to change other than the projection or is the USGS map non-convertible to feet?

Thanks.

Try changing the Elevation Display Units setting on the Vertical Options tab of the Configuration dialog to 'Statute' to get feet rather than meters in exported vector XYZ files.

Let me know if I can be of further assistance.

Thanks,
