Ah, then I guess that was not the relevant code for the problem I
experienced. I regularly update grass, and I never experienced this problem
until recently. Perhaps there was something wrong on my side in that case?
Irrespective, very glad it works again :-)

Thanks in any case!

Glad to hear it is working. BTW, the relevant code was last changed 2 years
ago.

That should not happen, it is an error in the method to remove small 
areas. Can you provide the vector map for testing (offlist)?

Hi Markus, the tool works as advertised after the latest revision. So 
perhaps this problem was related the the issue reported in ticket #3266? 
Thanks in any case!

That should not happen, it is an error in the method to remove small areas.
Can you provide the vector map for testing (offlist)?

[GRASS-dev] v.clean rmarea

2017-01-20 Thread Paulo van Breugel 

Hi devs,

I am trying to clean a map using v.clean. When using rmarea, any 
threshold values > 0.45 for rmarea results in 'ERROR: Failed to build 
new area'. From the manual I understand that the threshold for rmarea 
must be in square meters (also for latitude-longitude locations). With 
areas of polygons at least being 50m2, and mostly well above 1m2, I 
am not sure what is happening, any idea?
