| 摘 要： | 利用全新的外业数据调绘理念，在地图数据缓存切片技术、GPS定位技术及手持移动终端等技术设备基础上构建了地理国情与基础地理信息数据同步更新外业调绘系统，实现野外作业时，同一地物要素只需补测一次即可完成地理国情与基础地理信息数据的外业调绘工作，避免了重复外业采集生产，有利于降低地理国情与基础地理信息数据的更新成本。

| Abstract: | A new concept based on map cache slicing, GPS positioning technology and mobile terminal was proposed to build synchronous updating field surveying system of geographic national condition data and fundamental geographic information data.The system can implement that the same feature only needs to be measured once to updating geographic national condition data and fundamental geographic information data in the field.Repeated field production can be avoided by the system.Therefore the updating cost of geographic national condition data and fundamental geographic information data will be reduced. |
