Summary

笔记：记录ArcGIS ASCII Grid转为Idrisi Grid文件之方法。

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

In the subdirectory named StandardFile, the two files are the original Idrisi Grid files used in ANUSPLIN, for comparing the outputs of this case.

Result

The outputs of this routine both are correct entirely, by testing and comparing associated with the original file tmaxasu1.log.

Attached files (asc2idrisigrd.rar).
