[GRASS-user] v.net.distance - from feature was not reachable

Hi List, We are using v.net.distance to calculate the shortest path between two points on a river network, but have been experiencing some issues in both grass 7.4 and 7.9. In some instances, we need to add a new vector line (stream) to the river network, which we have done using v.patch as

Re: [GRASS-user] i.segment: band_suffix does not seem to have effect

Hi Moritz, Thanks for the hint. Indeed, I used the default region_growing method, not mean_shift. Maybe a warning message if band_suffix is given but not mean_shift method would avoid confusion? Or a note in the manual (or both)... Cheers Stefan Fra: Moritz

Hi, I'm trying to use this module for classification of an old aerial photos. After a segmentation (i.segment and i.segment.stats), I would to use a machine learning approach for the real classification. I tried with v.class.mIR which use also R. But there is an error and I don't know how to solve

Hi, I thought that if I give the band_suffix option in i.segment it produces bands with modified band values for all input bands. However, the option does not seem to have effect (no modified output bands are produced). Did I do or understand something wrong? Cheers Stefan
