Project Number: 6235-11210-006-48
Project Type: Reimbursable

Start Date: Jul 01, 2006
End Date: Sep 30, 2009

Objective:
1) Test repeatability of plot/transect location. 2) Test accuracy and precision of measurements. 3) Develop preliminary cost estimates for image acquisition and analysis.

Approach:
1) Select multiple fixed, marked locations and fly to each on 3 different days representing a range of weather conditions in order to test the ability of the UAV to revisit permanent plots or transects. 2) Collect images and complete ground-based measurements for multiple plots/transects representing a variety of plant communities; compare bare ground, vegetation cover and composition by plant structural group, and vegetation spatial structure calculated from the digital images and field measurements; compare the variance associated with each type of measurement as an indicator of precision. 3) Carefully track time required for each task and develop preliminary estimates of potential future costs based on automation and economies of scale.
