Mapping Grade Rovers
ToolikGIS provides a range of mapping grade receivers for use by station residents, administrators and managers. These are suitable for myriad applications, and all support the use of data dictionaries, allowing the user to enter field measurements and various attributes while recording the features in the field with the GPS. Data dictionaries can be customized to meet the users' field needs and offer very flexible and effieicnt data capture. With minimal processing after the user returns from the field, the data can be distributed in a variety of formats including tablular (e.g. excel), GIS (shapefile, coverage), or delimited text. Receiver A: Trimble GeoXT, with 2m antenna (Windows Mobile)
Receiver B: Trimble GeoXH, with 2m antenna (Windows Mobile)
Receiver C: Trimble GeoXH, with 2m antenna (Windows Mobile)
Receiver D: Trimble GeoXH, with 2m antenna (Windows Mobile)
Receiver E: Trimble Geo7x, with 2m antenna (Windows Mobile)
Receiver F: Trimble Geo7x, with 2m antenna (Windows Mobile)

Recreational Grade Rovers
ToolikGIS provides limited support for registered residents who bring their own recreational grade GPS units to the station. We can help users configure their GPSes and ensure that they are set to the appropriate coordinate system/datum for use with maps, coordinate lists and waypoints while they are working at Toolik. Users are expected to have and maintain any software required for their units, and to perform their own waypoint / data entry from information provided by Toolik GIS.

High Resolution Bathymetric Unit
ToolikGIS provides a high resolution bathymetric unit that we use to collect bathymetric data in lakes, streams and ponds around Toolik Field Station for registered users, administrators and managers. After data processing, ToolikGIS can use this data to create 2D and 3D bathymetric maps for use in field work or publications. Depth range for this unit is reported to be 0.3m - 75m.
