| Abstract: | Based on introducing the technology such as GPS, DGPS, RTK, VRS, PDA, expounded the work flow and application procedures of DGPS-PDA in continuous forest investigation based on VRS technology. Research shows that an average positioning accuracy can reach around 0.5 m, the precision can reach about 0.3m in some place where the signal is good, sample plot positioning accuracy and continuous comparability of CFI can be improved, and the efficiency of field data collection can be improved by PDA, the continuous forest investigation of paperless can be realized with this method. |
