Not to be left out of this great synergy amongst Fellow GPS users, I have 
processed a Trimble Data dictionary equivalent to FirePak.  This was 
modeled after the ArcPad Applet and Greg's code.  The attached Trimble 
Data Dictionary file (and export ASCII) will enable a Geo2, Pocket, Geo3, 
ProXR, Geo3CE running Geo3/AssetSurveyor/TerraSync to map fire perimeters 
once the data dictionary is loaded into a Trimble reciever.  Geo3CE folks 
can utilize the pen-based digitized method as well.

Notes on Use:  
1) Requires Pathfinder Office to Transfer to GPS reciever.
2) Joel created in 30 minutes using Pathfinder Office 2.9 Data Dictionary 
Editor.  
3) Pathfinder Office does not support nested menu logic ( for example, If 
GPS, then what Scale).  We therefore used the threw in all options for 
those attributes that switch over when using GPS or digitizing.  Entering 
nothing for MapSource when using GPS is the equivalent of a N/A

We kept to the same structure with other FirePak applets in order to 
assist in Direct import into GeoMac.  Two fields, Acres and Perim_miles 
cannot be written out until export and will be called "GPS_Area" and 
GPS_perime" in Trimble parlance.  Select "Area 2D" and "Perimeter 2D" in 
the export settings tab.  

Other fields such as Method, Date Collected, Time Collected, Differential, 
can be autoexported, but were included in the data dictionary for 
consistency and proper field ordering.
NOTE:   Projection, Datum are not required, since Trimble collected GPS 
data is projectionless and independent of raster backdrop. One can alter 
projection in Pathfinder Office to desired parameters, but again, these 
were kept in for GeoMac consistency.
**I Also included a Point Generic, Line Generic and Poly Generic features 
for Geo3 users.  Use these features to store ancillary features during 
collection.


PS:  great deals on a handheld GeoExplorer 3 (Under $2800) right now.  
Yep, no moving raster backdrop, but a killer soup2nuts package with the 
following standard options:
Full data dictionary editing capabilities
16 hour battery life (continuos use).
Enough memory for days worth of fire perimeter mapping
Pause button. Continue function.  Offsets.  Segment Control.
Easy to use keyboard and non-stylus approach - Have you lost your stylus 
today?
GPS quality filter control (From PDOP of 99 to 1!)
Import of GIS shapes for background display
Capability of 2 meter mapping given good conditions
