| 摘 要： | 为了对多幅小比例尺栅格图进行拼接与数字化,在MD下对扫描图进行不同标准纬线standard parallel的兰勃特投影。通过对几种投影方案的误差比较,得到最优方案,以较高精度完成栅格图的拼接与数字化,并分析误差产生的原因。

| Abstract: | To join and digitize small scale raster maps,many Lambert projections with different standard parallels in MD are carried out on scanned maps.By comparing the errors of different Lambert projection schemas,an optimal one is obtained.The joining and digitization are completed in higher precision,and the reason why the error has occurred is analyzed. |
