[QGIS-it-user] processing - v.generalize e DBF

Sab 27 Feb 2016 06:20:22 PST

Salve a tutti,
stamani ho provato a smussare un reticolo con (QGIS PROCESSING)
 v.generalize - metodo snakes 10 ma sempre con esito negativo e dava il
seguente errore:

You can check the log messages to find more information about the execution
of the algorithm

ho visto che è un errore legato al DBF quindi ho eliminato 15 campi dei 16
totali ed ora funziona bene.

chiedo se è normale tutto ciò e se esiste un numero massimo di campi nel
DBF che gestisce il processing di QGIS.

saluti
