Analysis of Polylines on both sides of separate polyline featureclass
Accepted Solutions
Hi James,
Check out the attached toolbox and python script. Please note this has had very limited testing so you should run this using a copy of your data in a file geodatabase and verify that the results are valid.
The tool uses road and footpath layers and a search distance as inputs. Also there is the option to specify a workspace if you want to keen the analysis layers used in the calculations.
Basically the script creates perpendicular lines from the mid-point of each road feature, these lines will extend out to your search distance value. The script then tests if the line intersects a footpath to the right or left of the road line and creates summary statistics that are added to the road layer. These are two new fields:
- PathCount - this should be either 1 or 2 (unless your search distances are too large)
- PathSide - Right, Left or Both
You can then calculate your percentage based on the number of PathSide = 'Both' records compared to your total road count.
Hope this helps.
