The purpose of this function is to show how point data (addresses for instance) snaps to the road network.

This is so you can fix possible issues in data, but also for other purposes (such as snapping GPS data to roads).

 

Input:

 

A point based table in either TAB or SHP format.

An ID field is also required to match the output with the input.

 

 

If choosing both a street name field and selecting "match with street name", it will search for the nearest link with the correct name.

If the name doesn't occur in the network at all, it will simply look for the nearest street.

 

If choosing both a street name field and not selecting "match with street name", it will search for the nearest link and report if the street name is correct.

 

If a street name field has not been chosen, it will simply search for the nearest link.

 

In all cases, it will also report the location, the distance in km and side of road (1: Right side, -1: Left side).

 

 

 

Here is a map of the sample data and the result of a calculation (red).

T/F shows if the correct street name was found:
