我们在野外做好纸质素描图之后,按照归档要求往往还要保存一份对应纸质图件的电子版备份,然而普通扫描之后的电子版的照片由于各种原因而达不到归档的要求,因此图件矢量化便成了一项必须要做的工作。矢量化地质图件是地质资料整理中的一项普通工作,也是很重要的一项工作,那么怎么才能保证矢量化图件的精确度,从而使得矢量化后的文件更加规整,更加美观呢?正确而简单的做法就是充分的做好准备工作-将原始的资料扫描文件进行校正。
After we make the paper sketches in the field, we often save an electronic copy corresponding to the paper map according to the filing requirements. However, the electronic version of the photos after the normal scan does not meet the requirements for archiving for various reasons Therefore, the vectorization of map files has become a must-do task. Vector geological map is an ordinary work in the geological data collation, but also a very important task, then how can we guarantee the accuracy of the vector map, making the vectorized file more regular, more beautiful? The correct and easy way is to be fully prepared - to correct the raw data files.
