摘要
通过GIS数据采集型GPS接收机在梅河口市曙光镇 1∶1 0 0 0 0土地利用数据库变更中的应用 ,对利用GPS进行土地数据库变更的外业数据采集的技术问题和方法进行了探索。将该型GPS采集的数据与全站仪采集的数据进行比较 ,可充分说明其在 1∶1 0 0 0 0比例尺图野外数据采集中可保证成图精度 ,且方便、高效。
This paper probes into the technical problem and method for database changing of land use making use of GIS model GPS receiver in 1∶10 000 scale land survey in Shuguang town of Meihehou city. The date acquired by GIS model GPS receiver is compared with another acquired by total station. And authors get a conclusion that the technique and method could ensure the precision of making map and is convenience and efficient.
