基于VRS技术的GPS-PDA在森林资源调查监测中的应用

Application of GPS-PDA in Inventory and Monitoring of Forest Resources Based on VRS Technology

介绍GPS-PDA软硬件组成及在外业建标、建模、数据验证、GCP采集、面积求算、专项调查等有关森林资源调查监测方面的应用。详细阐述Trimble Geo-XT移动站在森林监测中的应用实例和步骤,认为基于VRS技术的GPS-PDA在森林资源调查监测中具有定位精度高,定位方式灵活、可灵活定制调查表格、提高外业数据采集效率、数据兼容性好等优点。

This paper introduced the application of GPS-PDA in setting up standard, modeling, data vali- dation, GCP acquisition, area calculated, special survey on forest resources inventory and monitoring, and hardware and software building. Elaborated the application examples and steps of Trimble Geo-XT mobile station in the forest monitoring. Believed that on the base of VRS technology, GPS-PDA has ad- vantages in the investigation and monitoring of forest resources with high positioning accuracy, positioning flexible, and data compatibility, can be flexibly customized survey form, to improve data collection effi- ciency.
