笔记：记录ANUSPLIN输出Idrisi Grid文件转换为通用文件Geotiff之方法。
Specifications
Idrisi Grid data contains two separate files for description. One file extension is .img, storing values of the dataset. The other is .doc, as a text file including some properties of the dataset. Some specifications referred show in the following, which are not meaningful between words.
Pos'n error: x, y-position error assessment as RMS error
flag def'n: description of above flag value meaning
legend cats (Legend categories): text for legend
Completness, Consitency, Comments and Lineage: descriptive, use it if you have information
Note
The codes in this case is to be oriented to the files associated with Lat/Long coordinate system only. For others, I would code in the future probably.
Result
The output of conversion shows in the following figure.
