摘要
地理空间数据的属性不同,特别是坐标基准的不一致,严重地影响了数据的共享和使用。本文在介绍地图投影相关概念的基础上,详细论述了如何在ERDAS IMAGINE软件平台下实现图像的投影变换,解决不同坐标基准影像数据的共享,方便多源GIS数据集成。
Due to variance of user requirements, There come many differences in spatial attribute of GIS data. Especially the difference in coordinate system, has data share and application of GIS spatial data severely encumbered. Based on introducing some map projection concepts, this paper discussed how to carry out the transformation of map projection between raster images with different coordinate information under ERDAS IMAGINE platform in detail. The method solves the raster image share problem and various GIS data integeration.
