NRD Height Range Analysis
NRD Height Range Analysis Introduction In the STRIDE manuscript, currently in review, that presents a new “universal” travel rate function trained and validated on three separate field experiments, we examined the aboveground height range within which lidar point normalized relative density (NRD) was most predictive of travel rates. We found t...

Modeling Levan and Hovermap Travel Rates
Modeling Levan and Hovermap Travel Rates Author Michael Campbell Introduction In 2016, we ran our first travel rate experiment. Thirty-one study subjects walked 22 transects, each 100m in length, through central Wasatch foothills outside of Levan, UT featuring juniper-sagebrush vegetation. Study subjects were timed with stopwatches, the results...
