I've got a road network (line features) and a trip of GPS-Points. I want to join attributes from the road network to every point. So for each point i create a buffer. If the buffer intersects with a line feature, the attribtes are written to the point. That is all no problem. However I do not want to write attributes to points if the buffer intersects with to or more lines. Any ideas how to do this? I work in ArcGIS. Is there a way to do this without using python?

This can be achieved in several steps.

  1. Run a Spatial Join for your buffer polygons and road network layers (right-click the buffer polygons layer in the TOC and choose Join and Relates > Join). enter image description here

You will get an output polygon feature class which contains information on how many road features were located (even partially) within the buffered polygons. enter image description here

  1. Run a Join between the output feature class obtained in the step 1 and the source buffered polygons layer to find out which features you do not want to take into analysis (when you run Intersect and copying attributes).

  2. Either set up a definition query or do a selection > export data to a new feature class when you have selected those features that have either null or 1 values (which are valid in your case) in the Count field.

If you use ModelBuilder to automate the workflow, please use the Add Join GP tool and Spatial Join GP tool.

  • Thanks a lot. That should work. Any idea how i could do this in modelbuilder. I can't find the join from "joins and relates" from the TOC in the toolbox. – daverous Nov 22 '14 at 12:51

  • Here's a good way to work this out in modelbuilder geonet.esri.com/thread/35325 – daverous Nov 22 '14 at 15:08
