[Qgis-user] Reclassify field values from txt rule file in QGIS

[Kirk Schmidt]

Hi Fabio:


This is GRASS function and you can find an explanation at:

https://www.ibiblio.org/pub/packages/gis/grass/grass63/manuals/html63_user/v.reclass.html

Instead of a simple lookup table, some sql sytax is required.

9110 - (Hainsimsen-Buchenwald)    9110


you would require:


9110

where feature = '9110 - (Hainsimsen-Buchenwald)'or '9110 - 
(Hainsimsen-Buchenwald)(100.00000%)' ....


Note the single quotations for text.


An easier approach would be top calculate a new field using the field 
calculator and use the string left expression - left(/landclass field/, 4)
