Martin Feuchtwanger of Underhill Geomatics writes of their surveying utility program Copan. I don’t know much about surveying, but can at least list some features from the help file:
COGO Calculations
Multiple Inverse Calculations
Field Data Processing
Field Azimuths Data Processing
Resection Processing
Map Traverses
Map Checks
Area and Perimeter Calculations
Coordinate Transformations
Traverse Processing
Azimuth Expressions
Distance or Offset Expressions
Shift Expressions
Point Renumbering or Replacement
Supports Geodimeter, Leica, Wild, Nikon and TDS total station formats
And more …Copan comes in versions for Windows:

Palm:

And Pocket PC:

Feature sets are similar between the different versions, and data can be interchanged between them; GPS is supported for the mobile platforms. The software is free, but you’ll need to get a password and license key via email to use any of the versions. The Windows license key is in a “.bin” file, and some email services (like GMail) won’t accept files with that extension.

This looks nice – and free – though it’s considerably more specialist than the sort PDA/GPS software that we’ve been looking for here at MapAction, i.e. something to enter attributes, via pre-defined forms, for point and line features coming from the GPS. In other words, something like ArcPad, but simpler, and preferably free or low-cost! One good candidate is CyberTracker. Does anyone know of other similar mobile geo-data collection software?
