I have a polyline shapefile (1.500.000 road segments) and a point shapefile (the road segment's name). What is the most efficient way to update the polyline shapefile using info from the point shapefile.
Do i have to use a specific tool i.e SelectLayerByLocation_management and a cursor? Is there a more efficient way?
You could look into doing a spatial join which will join the two attribute tables based on their spatial location.
Hope this helps!
proximity is calculated for both of those using relationships described here
