摘要
以西南林学院为试验区,以TrimbleGeoXT为移动GIS的移动设备,实现了野外空间数据的实时采集和对历史数据的编辑和更新;通过后处理差分处理,实现了土地变更信息的亚米级精度。研究结果表明,移动GIS较之于传统方法在信息收集与更新数据方面有很大的优势,在以后国家的土地详查中值得研究与推广。
Taking Southwest Forestry College campus as an example, study on application of mobile GIS in monitoring for land use, which was based on Trimble GeoXT, was conducted.Real time spatial data collection and updating of historical land data on field were realized.And, the precision of land change surveying reached scale of sub meter by using differential GPS.The study shows that the mobile GIS has obvious advantage compared with traditional method in data collecting on field and data updating for land use;so, it can be used widely in land investigation.
