One of them contains roads. The other feature class represents sidewalks. I would like to determine the % of roads with sidewalks on both sides of the road. I'm curious to know if anyone has come up with a solution to this sort of question. Appreciate any advice or help!</P></BODY></HTML> Wed, 20 Aug 2014 18:00:20 GMT https://community.esri.com/t5/spatial-data-science-questions/analysis-of-polylines-on-both-sides-of-separate/m-p/657932#M1500 JamesBooth1 2014-08-20T18:00:20Z Re: Analysis of Polylines on both sides of separate polyline featureclass https://community.esri.com/t5/spatial-data-science-questions/analysis-of-polylines-on-both-sides-of-separate/m-p/657933#M1501 <HTML><HEAD></HEAD><BODY><P>Could you post a small part of both featureclasses? That will make it easier to see what implications there might be. This will probably require some programming in python or maybe in ArcObjects.</P></BODY></HTML> Thu, 21 Aug 2014 02:59:10 GMT https://community.esri.com/t5/spatial-data-science-questions/analysis-of-polylines-on-both-sides-of-separate/m-p/657933#M1501 XanderBakker 2014-08-21T02:59:10Z Re: Analysis of Polylines on both sides of separate polyline featureclass https://community.esri.com/t5/spatial-data-science-questions/analysis-of-polylines-on-both-sides-of-separate/m-p/657934#M1502 <HTML><HEAD></HEAD><BODY><P>Hi James,</P><P></P><P>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.</P><P></P><P>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.</P><P><IMG __jive_id="3773" alt="footpaths.png" class="jive-image image-1" src="https://community.esri.com/legacyfs/online/3773_footpaths.png" style="height: auto;" /></P><P>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:</P><UL><LI>PathCount - this should be either 1 or 2 (unless your search distances are too large)</LI><LI>PathSide - Right, Left or Both</LI></UL><P></P><P>You can then calculate your percentage based on the number of PathSide = 'Both' records compared to your total road count.</P><P></P><P>Hope this helps.</P><P></P><P>Owen</P><P><A href="http://www.spatialxp.com.au/">Spatial XP</A></P></BODY></HTML> Thu, 21 Aug 2014 21:59:05 GMT https://community.esri.com/t5/spatial-data-science-questions/analysis-of-polylines-on-both-sides-of-separate/m-p/657934#M1502 OwenEarley 2014-08-21T21:59:05Z Re: Analysis of Polylines on both sides of separate polyline featureclass https://community.esri.com/t5/spatial-data-science-questions/analysis-of-polylines-on-both-sides-of-separate/m-p/657935#M1503 <HTML><HEAD></HEAD><BODY><P>Sorry, I'm not allowed to post our data online.
