Distance between polygons

janehansen — Mon, 07 Oct 2019 18:16:21 GMT

Hi I am trying to find the distance between many polygons that represent parks. I have tried to run the proximity tool and the near tool but neither worked. All the polygons (multi) exists within one layer. I am hoping for some guidance on how to obtain the distances between each of these polygons.

Thanks

Jane

You should be able to use the Near tool. Just include your feature layer as both the input features and near features. It will calculate the distance between all your features within the layer.

Thank you, that worked

I just noticed that the results from the near tool did not include the largest polygons. For smaller polygons the distance was calculated, for the 4 largest, and most important to my analysis, the distance using the near tool was 0.

The layer I used was the original layer, I did not merge any new parks with the original layer.

Any ideas why these parks were not calculated?

Thanks,

Jane

Hi Jane

Having a distance of 0 may indicate that these features are overlapping or touching. If they are not, then check for any multipart features that may be influencing the results. I also frequently use the Repair Geometry tool if anything usually looks amis.

The polygons are not overlapping or touching. I will try the repair

geometry tool and see if this makes a difference.

Thanks for your input

Near tool not works in polygon to polygon features
