Elevation Measurement Capabilities of Consumer-Grade Global Positioning System (GPS) Receivers
Elevation determination is central to many natural resource–related measurement tasks including establishing terrain profiles, determining road and stream gradients, and volume estimations of soil or water. We examined the relative vertical accuracy of six consumer-grade global positioning system (GPS) receivers that were rigorously tested at three different measurement courses in western Oregon. Each measurement course was in a distinct setting representing either open sky, young forest, or closed canopy conditions. Overall, we found that average vertical errors were 7 m or less for five of the consumer GPS receivers that we tested and that measurement reliability varied among the units. This level of accuracy may suffice for developing estimates of feature profiles and initial draft design applications depending on project requirements.

More about this publication?
- The Journal of Forestry is the most widely circulated scholarly forestry journal in the world. In print since 1902, the Journal has received several national awards for excellence. The mission of the Journal of Forestry is to advance the profession of forestry by keeping forest management professionals informed about significant developments and ideas in the many facets of forestry: economics, education and communication, entomology and pathology, fire, forest ecology, geospatial technologies, history, international forestry, measurements, policy, recreation, silviculture, social sciences, soils and hydrology, urban and community forestry, utilization and engineering, and wildlife management. The Journal is published bimonthly: January, March, May, July, September, and November.
