Hi How are you? After solving thanks to Stefan and his r.slope.direction how to calculate the slope along the keyline, now I have to solve how to create parallels to the keyline. Nothing easier: see parallel! But I have to create many. In the graphical modeler I can't learn how to use the loop. Damn if I'm ignorant. But maybe v.mapcalc would also be very handy. But it doesn't work for me. After installing ply it doesn't work anyway. > Traceback (most recent call last): > File "/usr/lib/grass76/scripts/v.mapcalc", line 429, in > <module> > sys.exit(main()) > File "/usr/lib/grass76/scripts/v.mapcalc", line 415, in > main > p.parse(expression) > File "/usr/lib/grass76/scripts/v.mapcalc", line 191, in > parse > self.parser.parse(expression) > File "/usr/lib/python2.7/dist-packages/ply/yacc.py", line > 333, in parse > return self.parseopt_notrack(input, lexer, debug, > tracking, tokenfunc) > File "/usr/lib/python2.7/dist-packages/ply/yacc.py", line > 1063, in parseopt_notrack > lookahead = get_token() # Get the next token > File "/usr/lib/python2.7/dist-packages/ply/lex.py", line > 393, in token > newtok = self.lexerrorf(tok) > File "/usr/lib/grass76/scripts/v.mapcalc", line 146, in > t_error > (t.lineno, t.value)) > SyntaxError: syntax error on line 1 near > ''buff_l(keyline@PERMANENT,5)'' I used all possible quotes in the expression, but the result is always the same
I don't want to use qgis (where there would be offset) because r.slope.direction is in grass and it is very convenient, and also all the rasters I use have them in grass. I would like to learn how to do everything in GRASS. Well, who knows if I'll succeed. As soon as I have some pennies I pay a friend of mine who is a python developer: maybe it's better.
