Hello.
I used this software to mark monitoring wells for groundwater sampling. One site in particular is vast in size, and has tremendous terrain variations. I worked in bright sunshine, and rain. Overrall, it was a breeze to set up and use.
Here are a few issues:
Reading the Ariel in daylight is a lot harder than the topo, is there a way to inverse the color scheme???

I cannot seem to export my waypoint coordinates!

I would also like to IMPORT (XY data?) from my GIS dept. so that I don't have to locate and mark my self. (we use beacon GPS on some sites to generate the XY data)
I cannot effectively show someone a map on the monitor, only the PDA. A desktop viewer version would be awesome! If you are programming in .net, this should be a lot easier to do these days.
GPS reconnect, I had to turn the power off a lot (I only had 1 battery) and had to manually reconnect the gps.
I had to use the pen to mark waypoints, did I do something wrong? I would rather use the absolute current GPS coords for this, rather than moving my well 10ft over!
Other than that, those are my thoughts.
While you seem to be working on the tracking feature, please keep waypoint import/export in mind!!!! Thanks!
Great software by the way, I will be presenting this to my co-workers in a couple of months. I develop field-based data import software for the pocket pc, and this beauty goes hand-in-hand with environmental engineers.
