[Gfoss] strano problema in saga gis

Local Chapters GFOSS.it
1

dopo avere creato un dtm in saga gis e provo ad esportarlo in formato ascii o
Gtif, aprendo questi ultimi file in qgis mi succede che li dove c'erano
delle depressioni ora ci sono colline e viceversa,mi inverte stranamente le
quote come se il raster si vedesse al contrario.vi è mai capitato?

semplicemente ho fatto un sezione con profilng tool in qgis e dove c'è un
torrente le quote sono dal basso verso l'alto e non viceversa

Mah, per essere sicuro al 100% che davvero le quote siano ribaltate, ti
consiglio l'eccellente plugin VALUE TOOL => opzione ENABLE

è stranissima la cosa ,ho scritto anche a Volker Wichmann che mi ha risposto
cosi:
/Sorry, but I have no idea what could be causing this problem. With QGIS,
you should also be able to open the SAGA grid directly (using the *.sdat
file) instead of exporting it to another format./
ps come apro il file in qgis che non ho capito?
grazie

CTRL-SHIFT-R e scegli il formato "Saga GIS Binary Grid" :slight_smile:
