Update shapefile's field using nearest shapelife

[sotokan80_]

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?

Hi, 

You could look into doing a spatial join which will join the two attribute tables based on their spatial location.

Hope this helps!

Near tool? Spatial Join? etc? depends on what you want the final results to look like

The distance between point and polyline is calculated from polyline's middlepoint?

not with Near Near—Help | ArcGIS Desktop or spatial join Spatial Join—Help | ArcGIS Desktop 

proximity is calculated for both of those using relationships described here
