I have vector maps called "incidents" (points) and "roads" (lines). For some reason, I am getting nothing as output in the final attribute table; that is, the attribute table is not being updated at all. I am sure I am making some silly mistake.
v.distance from=incidents to=roads output=connecting_lines upload=cat column=nearest #I copied table "incidents" to "connecting_lines" and called it "connecting_lines". I used the option #key=nearest. I added two columns called end_x and end_y, both double precision. v.net input=connecting_lines output=nodes operation=nodes alayer=1 nlayer=2 #I also tried swapping alayer and nlayer with no luck. v.to.db map=nodes type=point,line,boundary,centroid layer=1 qlayer=1 option=end column=end_x,end_y The output I get from v.to.db is: 1 categories read from map 30831 records selected from table 0 categories read from map exist in selection from table 0 categories read from map don't exist in selection from table 0 records updated/inserted 0 update/insert errors What could I be doing wrong? -- View this message in context: http://www.nabble.com/Nothing-Inserted-into-Attribute-Table-from-v.to.db-tp19793008p19793008.html Sent from the Grass - Users mailing list archive at Nabble.com. _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
