Summary

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

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.
