Photo control for georeferencing an AHAP (1:60,000) photo. Record cabin (points) location for fire. Need to learn enough about each system to know when to use the tool. Sorry… It’s a Multi - Tool Environment. GIS skills support is high (design forms, maintain/move data). Purchase of ruggedized collectors($900 - $3000). Not a tight package (GPS, cables, ipaq, cradle, software, data). Now can select GPS Filters (SNR, PDOP). GIS/GPS Field Mapping ToolsPros and Cons Need to post-process after the field (internet connection). Under Canopy issues - Velocity filtering / Use Antenna. #How to get gps pathfinder office to export prj file software
Excellent software (Pathfinder Office). No Data Dictionary capability Large Errors!. Not designed for GIS Mapping - relies on 3rd party software. No GPS Filters (2D Fixes Given, SNR, PDOP, MASK Angle set to 5). Integration into ArcView - relatively straightforward. Fun / easy to use and easy to navigate with. Cheap and consistent 15 meters positions - okay under canopy. Application builder($1500) Garmin and IPAQ running ArcPad. Unlimited Storage (dependent on storage capacity of device). Realtime display of vector /raster data. Data Dictionary, Mission Planning Trimble. Moving Base Maps (1:100,000 scale) Garmin RealTime Kit. GPS/GIS Field Mapping Tools Nerd Factor. Able to Differentially Correct (Realtime or Post-process). Capable of Datum Transform - To NADCON 27. Data Dictionary (Name, Trail Width, Comments). Capable of Controlling Attributes in the Field. Export in GIS Friendly Formats (shapes, coverages, DXF). Good on Batteries No Problem! Most Likely With Effort Tip: A Pause button is crucial to creating clean line/poly data in the field. Able to Average Positions into a Point.

Mapping Grade Receivers : Collected directly in the field as a line / area feature. String of positions converted into a line / area. Recreational Grade Receivers : Called “Waypoints”. Mapping Grade Receivers : Called “Points”. Point features are one or more positions averaged into a point.

Baselines have significantly decreased Tip: For every 100km between base and rover, add additional 0.1m of error. Dependent on the CORS Statewide Network and community base stations. 
Poor under any canopy Tip: Other Satellite DGPS systems like StarLink do not cover AK.3 meter solution (if the GPS is enabled).2 Geostationary satellites (parked over equator).Dependent on the CORS Network - Gulf of Alaska:.In Alaska - depends on where you are at and how lucky you are.Any system that can remove atmospheric errors in a GPS solution (greatest error after SA).
Differential Global Positioning System (DGPS).Since Selective Availability SA was turned off….
