Assessment of low-cost GPS receiver accuracy and precision in forest environments

P. 159-167Selecting the apppropriate receiver is an issue when a major portion of global positioning system (GPS) data collection is below forest canopies. This study compares four low-cost GPS receivers, in order to determine the most suitable receiver for position assessment under differnt forest canopy covers, in terms of ease of use, accuracy, and relability. A total of 33 positional assessments were gathered per receiver, plot, and method, in 18 forest location.S
