Hi,
I have selected some training areas to apply supervised classification using g.gui.iclass in Grass 7.0 windows 64 bit. I could exported the training areas to a vector map to save my work but I cannot import the vector into g.gui.iclass to rerun the analysis.
I got the following error:Traceback (most recent call last): File "C:\Program Files (x86)\GRASS GIS 7.0.0\gui\wxpython\iclass\frame.py", line 537, in OnImportAreas self.ImportAreas(vName) File "C:\Program Files (x86)\GRASS GIS 7.0.0\gui\wxpython\iclass\frame.py", line 594, in ImportAreas self.poMapInfo = digitClass.OpenMap(vname, tmp = True) File "C:\Program Files (x86)\GRASS GIS 7.0.0\gui\wxpython\vdigit\wxdigit.py", line 1649, in OpenMap self.poMapInfo = self._display.OpenMap(str(name), str(mapset), update, tmp) File "C:\Program Files (x86)\GRASS GIS 7.0.0\gui\wxpython\vdigit\wxdisplay.py", line 962, in OpenMap Vect_set_updated(self.poMapInfo, True) # track updated lines at update modeWindowsError: exception: access violation reading 0x000002E4
I could open the vector in the display but not import it into g.gui.iclass. When I opened the vector attribute table I can see all 3 categories, but it is not specified how many training sample are within each class. Is that correct?
Thanks in advance for any help.
