数字测图在地理信息系统中的应用与探讨

Application and study of digital mapping in geographic information system

以目前的测图方法和测图软件生产的数字地图要进行大量的编辑工作才能满足GIS对数据的要求,所以测绘工作者应改变传统的数据采集理念,在数字测图野外数据采集和内业成图过程中应充分考虑GIS数据入库的需要,从而生产出既符合规范要求的数字地图,又可较方便地将数字地图转入地理信息数据库。

Using the current survey measurements and survey software, the data need to be edited in order to meet the demands of the GIS. So the surveyor should change the traditional idea of data collecting, fully consider the requirements of the GIS in the digital field data collecting and inside mapping. The digital drawings can fit with the national specification for Cartographic System, and also can be transformed conveniently to the GIS database.
