Help needed in calculating route distances

ElinaNieminen — Tue, 15 May 2012 10:53:40 GMT

Hi,

I have a problem in calculating the route distances for my almost 900 points containing shapefile. I know how to do it separately for each point, but is there a way of doing it for all the points at the same time? I would need the distances in meters from each point to the city centre using roads.

Another thing, I would also like to count the route distances to parks, which are polygons. Is this possible?

Thank you if anyone could help me, please.

Elina

Hello Elina !
You can easily compute all the distances between your points and the city centre with the Closest Facility tool (Network Analyst). You can load the city centre as "Facilities" and all the other points as "Incidents". Just have a look at the ArcGIS help here:
http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//00470000004n000000
Also have a look at the OD Cost Matrix help.

As far as I know you can't use polygon, maybe you could just compute its centroid and then just load it as a "Facilities".

Best regards,
Theo

Thank you Theo!

I will try to do it that way. In case of parks, maybe I could put points to the entrance points to the park and thereby calculate the routes to these points to see which is closest.

With kind regards,
Elina
