基于VRS技术的GPS-PDA在森林资源调查监测中的应用

摘要

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, dala validation, 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 Ceo-XT mobile station in the forest monitoring. Believed that on the base of VRS technology, GPS-PDA has advantages 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 efficiency.
