系统借助eSuperMap二次开发SDK搭建基于Pocket PC的嵌入式GIS开发平台,结合森林资源调查规划守则及传统野外实地调查时所遇到的诸如林班边界定位精度不高、数据采集录入繁琐等问题,设计开发出森林资源调查手薄软件系统。组件式技术确保了GIS在PDA上的灵活制定,充分利用了嵌入式设备的硬件性能;通过实现与GPS接收器的蓝牙通讯接口,有效的提高了野外调查定位精度。系统的实现缩短了森林资源调查周期,提高了定位精度并有效降低了工作量,为森林资源调查工作及数字林业建设提供了技术支持。
The system uses the eSuperMap secondary development SDK to build an embedded GIS development platform based on Pocket PC. Combining with the planning guidelines for forest resources survey and the traditional field investigation, the system encounters such problems as poor positioning accuracy of the Linban boundary and complicated data entry, Design and development of forest resource survey software thin-walled system. Component-based technology ensures the flexible development of GIS on PDA and makes full use of the hardware performance of embedded devices. By implementing the Bluetooth communication interface with GPS receiver, the accuracy of field survey positioning is effectively improved. The realization of the system has shortened the cycle of forest resources investigation, improved the positioning accuracy and effectively reduced the workload, and provided technical support for forest resources investigation and digital forestry construction.
