Assessing effects of positioning errors and sample plot size on biophysical stand properties derived from airborne laser scanner data. (2009, methodology): “, using two GPS receivers — one base receiver located at a known position and a rover receiver used in the forest at unknown positions — indicated positional accuracies of 2–6 m with techniques based on coarse/acquisition code (Deckert and Bolstad 1996; Næsset 1999; Næsset and Jonmeister 2002).”
A best practices guide for generating forest inventory attributes from airborne laser scanning data using an area-based approach (2013, unknown): “…receivers, positional errors associated with ground plot locations in forested environments typically range between 1 and 5 m (Deckert and Bolstad 1996; Næsset 1999; Næsset and Jonmeister 2002; Bolstad et al. 2005; Wing and Karsky 2006; Wing and Eklund 2007; Wing et al. 2008; Edson and Wing 2012).”
