摘要
MAPGIS是在地质行业,尤其是在地质图的制作过程中被广泛应用的一种地理信息系统。本文结合工作实践,总结了在MAPGIS地理信息系统中利用投影变换将数据文件转换并建立成统一参数的数字图件,有效提高了地质图的精度和质量。
MAPGIS is a geographic information system which is widely used in the geological industry, especially in geological mapping. On the basis of practice, the paper sums up a method that can convert data files into digital maps with unified parameters using projection transformation in MAPGIS geographic information system, which is effectively improves the accuracy and quality of geological map.
