摘要 详细研究了影像地图缓存不同层级分辨率计算方法,不同层级瓦片裁切数量的计算方法,裁切过程中单张瓦片部分区域超出影像图边界的处理方法。通过GDAL开源库,实现影像地图缓存裁切程序。 The article research on the image map cutting different levels of resolution calculation method, calculate quantity of differ- ent levels tile method, cutting tile area out of image boundary handle method. Through the GDAL Open - Source library to achieve the image map cache cutting program.
