I have a polygon area in ArcMap on one layer, and I would like to calculate the mean, max. and min. distances to other features types on different layers.

I've used the Measure tool ruler, but was wondering if there was a better tool in the ArcToolbox?

Thanks for assistance with this!

I need to measure the distance of these points from the polygon:

Hi TP Mann,

I am not sure exactly what you mean by: "calculate the mean, max. and min. distances to other features "

There are various tools available to you to calculate distances between features in ArcMap.

Take a look at the following options:

1. Spatial Statistics Tools -> Measuring Geographic Distances -> Central Feature (or Mean Center) on your set of points.

2. Analysis Tools -> Proximity -> Point Distance tool to get the distances.

3. (Hawth's Analysis Tools for ArcGIS) http://www.spatialec...pntdistbetw.php

For ArcGIS related questions, I would recommend you post your problem or search for answers on the ESRI support forums:

http://support.esri....=forums.gateway

as these forums deals specifically with ArcGIS 'how to" problems.

Hope this helps,

Susan

I recall Hawth's Tools (Google that) having the functionality to determining distances between layers. I'm not sure either as to what you mean by "mean,max and min" distances unless you are referring which distance is greatest out of all the points... pls clarify. You will have to make sure to use a projection (e.g. conformal) that supports distance / angular measurements (i.e. don't use a geographic coordinate system).

Thank for the suggestions, the Hawth's Tools were just what I needed!

Also thanks for the info about projections, will take that into account.

Cheers.

I think it could be important to note that the distances measured are euclidean distances. This measurement would not consider the curvature of the earth, as the geodetic distance would measure.
So your measurements would be invalid. Of course the longer you measure, the more deviance you will get.
Correct me if i am wrong.

I have a question along the same lines as TPMann. Using the line drawing tool is there a way to have a label automatically created showing the distance of that line. The answer may be above but I'm still a nub.
