Conclusion
Spatial Data Collection
Field Data collection is incorporated into a variety of classes.
– Hydrology
Stream cross sections
– Geomorphology
Glacial landforms
– Lakes & Environmental Change
Lake Cores
Lake Bathymetry
– Advanced GIS (GS 318)
Forest plots: species
Water Quality
Walkability
Trail mapping
– Independent Studies/Internships
Ambient Noise levels
Geology Field Sites
Ecological Management Zones
Forest Storm Damage
Land cover change
– Physical Geography (GS 101)
Surface temperature and
Relative humidity
– Environmental Science (EV 150)
Dendrochronology
Water Quality
Stream cross section
– Introduction to GIS (GS 165)
Forest plots: species
Water Quality
– Remote Sensing (GS 218).
Forest plots: conifer vs
deciduous
Surface temperature
Lake turbidity
Dendrochronology for Environmental Science class Assignments
Compare Ring Width to
Growing Degree Days and
Temperature.

Reforestation and species change
Walkability and Bike-ability
Urban infrastructure
– Community Gardens
– Urban Art
Ambient Noise Levels
Stone Walls and Landscape History
Lake Studies
– Water Quality and Temperature
– Lake cores and climate history
– Bathymetry
Antarctic Dry Valley glacial history
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
