topic Get polylines which touch (endpoints) of a given polyline in Geoprocessing Questions https://community.esri.com/t5/geoprocessing-questions/get-polylines-which-touch-endpoints-of-a-given/m-p/455529#M15315 <HTML><HEAD></HEAD><BODY><SPAN>Hello all,</SPAN><BR /><BR /><SPAN>Somewhat familiar with GIS and Python/scripting languages but very new to integrating the two. I have a polyline shapefile of street centerlines for a city. These centerlines have a Boolean field for whether or not they contain a bike lane. My desired end product is a table/list of bike lane corridors (i.e. "Main Street") and the start and end intersecting (touching) streets (i.e. "1st Street" and "9th Street"). To do this, I think I need to do the following:</SPAN><BR /><SPAN>- Create a list of all unique bike lane corridors - i.e. I may have several adjacent "Main Street" polylines with bike_lane set to TRUE but would only want to count this street once (equivalent of an SQL SELECT DISTINCT)</SPAN><BR /><SPAN>- Loop through each distinct corridor and find the endpoints</SPAN><BR /><SPAN>- Extract the information (really just 'Street Name') of the polyline(s) touching each endpoint</SPAN><BR /><BR /><SPAN>Does this request make sense? Again, my end result would be something like:</SPAN><BR /><SPAN>1. Corridor: Main Street, Start Point: 1st St, End Point: 9th St</SPAN><BR /><SPAN>2. Corridor: Market Street, Start Point: Water St, End Point: Ridge St</SPAN></BODY></HTML> Tue, 26 Nov 2013 21:39:49 GMT AnthonyGallo 2013-11-26T21:39:49Z Get polylines which touch (endpoints) of a given polyline https://community.esri.com/t5/geoprocessing-questions/get-polylines-which-touch-endpoints-of-a-given/m-p/455529#M15315 <HTML><HEAD></HEAD><BODY><SPAN>Hello all,</SPAN><BR /><BR /><SPAN>Somewhat familiar with GIS and Python/scripting languages but very new to integrating the two.
