I am aware of the issue, I tried increasing tolerance, with no results. That happened with EPSG:4326; when switching to a metric CRS, it works. My interpretation is that setting a too high tolerance, easy for degrees (e.g. 1 degree is huge) makes it impossible to compute the path. Maybe the user should be warned about this. >> * the new widget to get coordinates from canvas is supernice, can it be >> uses for other modules (e.g. r.viewsed, and others from GRASS) as well? > > This widget was added about year ago or even later (can't remember exactly > when > I made it). And of course it can be used in any Processing algorithm. So better if I go through all the algs and list those who need it in a ticket? >> * in case of projected layers, the coords as taken from the canvase >> should be backprojected to original layer CRS. > > This is known issue and it is also happens for extent selector.

Related ticket https://hub.qgis.org/issues/15680. oh, I should know about this ;) >> * several commands are still missing to be on par with GRASS v.net >> modules: would it be usefult to make a list of missing functionalities? >> Should I fill tickets not to forget about it? > > Well, I never thought about being on par with GRASS and don't know if this > makes > sense. I do not see why not, e.g. che chinese postman, etc. Thanks a lot. -- Paolo Cavallini - www.faunalia.eu QGIS & PostGIS courses: http://www.faunalia.eu/training.html https://www.google.com/trends/explore?date=all&geo=IT&q=qgis,arcgis _______________________________________________ Qgis-developer mailing list Qgis-developer@lists.osgeo.org List info: http://lists.osgeo.org/mailman/listinfo/qgis-developer Unsubscribe: http://lists.osgeo.org/mailman/listinfo/qgis-developer
