Abstract
This study quantifies area and perimeter measurement errors, traverse times, recording intervals, and overall time and cost effectiveness for using a mapping-grade differential Global Positioning System (GPS) receiver in forested settings. We compared two configurations including one that maximized data collection productivity (position dilution of precision (PDOP) 20, signal to noise ratio (SNR 33), and minimum elevation mask 5°) and a second that involved traditional receiver settings that was designed to improve accuracies (PDOP 6, SNR 39, and minimum elevation mask 15°). We determined that averaging 30 positions and using the settings that maximized productivity was the most time effective combination of recording interval and settings. This combination of recording interval and settings proved slightly more cost effective than other traditional surveying methods such as a laser with digital compass and string box. Average absolute per cent area errors when averaging 30 positions and using maximum settings were 2.6% and average absolute per cent perimeter errors were 2.0%. These results should help forest resource professionals more effectively evaluate GPS techniques and receiver configurations.
2 Lesson 4 - Timber Cruise LEAF 9-12 Field Experience Unit TEACHING SITE Classroom, computer lab, and forested site VOCABULARY Angle gauge: A tool used to estimate the basal area of an acre of forest. It is designed so that each tree sample from a center point represents a pre-determined amount of basal area (this is its basal. PC-Cruise is designed to be powerful and easy to use. PC-Cruise is a super-set of PC-GIS, PC-GPS and PC-Mapper. Therefore, you will find all of the mapping functions and Forester's tools that you need in the PC-Cruise software. Major innovation: GPS/GIS Based Timber Cruising. PC-Cruise is the only software product,.
