Hello,
I have been struggling for a while with trying to collect an accurate Z-Value.
1. Currently I am checking out data from ArcMap to be used in ArcPad. I am collecting Accurate GPS data for a point layer. We are taking a tablet PC along with a Trimble ProXH into the field and collecting accurate coordinates. On the geography page of the attribute table while the GPS is collecting data, you can see XY and Z values are being generated...(See Attachment for a visual). When I hit OK the X&Y values stay saved in the attribute table but the Z-Value goes back to Zero. Is there something I need to change in the settings of ArcPad or the layer structure that will make the Z-Value save?
2. I have taken a notepad with me and wrote down a few Z-Values before hitting OK. These values are not very accurate, sometimes over 100ft off. Are there preferences or settings that I need to setup for Z-Value collection? The GPS and Antenna that I am using is collecting sub-foot accuracy for XY coordinates after post processing, so i figured it should be able to collect at least sub-Meter accuracy for Z-Value. Am i making false assumptions here?
Any help that you can provide to me would be appreciated,
Thanks,
Jerry
