I had some students a month ago do some mapping with Arcpad in a mobilemapper. The shapefiles that were generated only seem to have the x and y data, not the z data recorded (or visible in the attribute table/dbf file). Is there a way to get these data in Arcmap? I'd like to use them to convert an arbitrary grid to UTM. I can do this for easting and northing but not for elevation without the z data. Is there a reason why these data are not showing up? Were they not recorded by Arcpad in the mobilmapper when they recorded points? Is it possible to go back to the mobile mapper and find out the z data as recorded in the unit? Or are these data basically now gone?
