Good day guys,
I came across a problem in the v.generalize module. I do the following:
v.generalize [EMAIL PROTECTED] output=myvect_smooth type=line
method=hermite threshold=10
I then do a v.out.svg and noticed the following line in the svg file:
<path gg:cat="31" d="M 111.500000 -80.500000 l 8.734748 4.771559
9.907176 6.337565 nan nan nan nan nan nan nan nan nan nan" />
Any idea how I can get rid of those nan's? They cause stuff such as
v.to.rast to hang.
I cannot reproduce this with the speafish60 dataset:
v.out.svg [EMAIL PROTECTED] output=roads type=line precision=6 layer=1
and
v.generalize [EMAIL PROTECTED] output=roads_smooth type=line
method=hermite threshold=10 look_ahead=7 reduction=50 slide=0.5
angle_thresh=3 degree_thresh=0 closeness_thresh=0 betweeness_thresh=0
alpha=1.0 beta=1.0 iterations=1 layer=1
v.out.svg [EMAIL PROTECTED] output=roads_smooth type=line
precision=6 layer=1
Both give me svg files without nan's.
Can you reproduce this with spearfish data ? Can you look at the line
with cat=31 in your grass vector (maybe in v.digit) and see if there is
anything abnormal about it ?
