nearest point for every point in a layer

ReginaldCarlier — Tue, 03 Aug 2010 12:37:51 GMT

Hi,

I have two layers who need to be combined into one layer. One layer has firehydrants and the other has address information. For every firehydrant I need the nearest address.
Is there a (free) tool or method to achieve this or do I need to write my own tool?

thanks in advance.

Reginald

Reginald,

There are several free tools that will answer your question. Get into the habitat of checking out ArcScripts where other users have put up their tools for free.

Goto here: arcscripts.esri.com

and type in "nearest point"

You'll be amazed whats up on this web site.

ArcGIS does this out of the box. In ArcToolbox, navigate to Analysis > Proximity > Near. This tool determines the distance from each feature in the input features to the nearest feature in the near features, within the search radius.

Please do remember that not everyone has an "out-of-the-box" version of ArcInfo, check the help

Near(Analysis)
Licensing Information
ArcView: No
ArcEditor: No
ArcInfo: Yes

so such basic GIS questions can only be answered unless you have paid the price.

Hi Eric,
I used the same Near Tool to get points-to-point NEAR_DIST, NEAR_ANGLE, NEAR_X, and NEAR_Y of zipcodes. I'm using ArcInfo 10. I'm getting the same NEAR_X and the same NEAR_Y values for all records! What have I missed?
Please help.
Thanks,
Al Tongco

Greetings,

I just noticed something about the Near tool. If you do not specify a value in the "optional" Search Radius, no features are returned when performing a point to polygon near analysis. Not sure if this might help your problem with the same coordinate values returned for all of your features but it might be worth a try to enter a value large enough to encompass all your features and see if the result is different.

Regards,

Bill
