Hmmm. An easy one to try first would be to run Remove duplicate vertices on the pipes layer before extracting the vertices - I don't know if there will be any. Another thought is you said the pipes are MultiLineString, if a single pipe asset branches you will get two vertices at the same location - one for each part. To remove these "duplicates" you would need to Dissolve the vertices using pipe id as the dissolve field.

Multiple matching features found at same distance from search feature, found 3 features instead of 1 x 60-70 time; 2. Feature could not be written to C:/Users/Matthew/Box/Modelling Project/Model Data/GIS/Project/Asset Distances Model/Outputs/pipe_road.csv x 11. There are many pipeline segments (33, 000+) and many roads. The output file of the results looks okay, but there are just too many entries to verify. Any suggestions? | |
