ERDAS在1∶1万地形图调绘片纠正中的应用

Application of ERDAS in 1∶10000 Identified Photograph Correction

本文介绍利用ERDAS的几何纠正功能对1∶1万调绘片进行纠正的原理和方法。实验证明此种方法的纠正结果不仅可以保证较高精度而且与DLG数据叠加具有良好效果,可以作为底图进行数据编辑。

This paper introduces the Principle and method of geometric correction for 1：10000 identified photograph based on ERDAS. The result indicate that corrected identified photograph has high precision and good results overlay with DLG Data. It can be used as base map for data editing.
