GPS Data Collection

Garmin GPS units

– GPSmap 60CS, GPSmap 60CSx

~$300 New

– Waypoints: captures elevation, date,

lat-long, automatic ID assigned.

– Routes: captured automatically unless

turned off.

GPS dongle for laptop

– Full ArcMap functionality.

Trimble GPS

– Juno series: SB, 3B ~$800

– Runs ArcPad

Garmin GPS 60CSx Data Collection

Waypoints for Point locations

– Attributes were entered into the Ident Field (14 character limit)

– GPX Data converted to Shapefiles with DNRGPS

– Multiple Attributes could be parsed out with String functions in Arc.

– Data from each unit had to be merged

– Use for activities minimal attribute collection: surface temperature, RH

Tracks for Trail mapping

Geology Field Sites

Students identify locations for potential

field activities, create ArcMap projects

and take photos.

– Locations taken using Garmin GPS 60

– Photos taken with student cameras

– Data linked using hyperlinks in ArcMap

project

ArcPad data collection

Based on the Geodatabase

– Multiple Attributes

– Defined domains; range or coded

– Attribute collection dialog

ArcPad project created from Extension dialog in Arcmap.

– Identify editable layers; Existing features or Schema (to add features)

– Specify background data

Deploy project to Trimble units using Microsoft Mobile

After Field Collection copy data from unit onto network

Start edit session and import data with ArcPad extension dialog.

Issues

Cannot create features and then export for editing, must start new blank

project.

Must import edited features on the same PC

Collecting Data

Sampling Strategy

– 10 meter radius circle sample site

– Method of collection – GPS Unit.

Data Collected

– Measure and determine the

species of each tree (greater than

5 cm DBH) within the site.

– Count saplings.

– Measure dead wood on the

ground.

– Core 2 largest trees (2 cores each)

Conclusion

Use of Collector for ArcGIS has facilitated.

– Greater participation in field data collection.

– Dramatically reduced the cost of GPS collection.

– Improved compilation of data post collection.

– Empowered student and faculty researchers.

Future work

– Develop ArcGIS Server

– Student deployed projects

– Work with Community groups
