Calculate distance between points

GeorgeDurkee1

Hi:

Within Pro desktop, I'd like to calculate the distance between points. The points are in the same feature class and would want to limit distance to neighboring points within, say, 40 meters. There's a total of about 200 points.

To make it even more fun, generating a line labeled with the distance between each neighboring point would be great.

I'm looking at a recent destructive wildfire and wanting to better visualize the effects of radiative heat on igniting nearby structures vs. embers vs. vegetation height profile from lidar.

Just FYI, I've included a map of the area. Yellow crosses are homes destroyed, green squares survived. At the moment, the strongest correlation is total canopy cover though I'm also going to look at veg in the 1 - 4 meter (ladder fuels) profile as possibly the difference in areas where there's mixed destruction/survival of structures.

I'm pretty useless at writing expressions so any help is really appreciated!

Thanks,

George

Did you look at

Near (Analysis Tools) | ArcGIS Pro documentation

the same featureclass can be used for "within features" distance measures.

I would start with that

... sort of retired...

Dan: Hi. Mucho thanks. I just tried one run and it does much of what I want to do. I'll fiddle around with the tool some more but, with labels and setting a diameter, it'll show me useful information.

Again, thanks!

Near would be my first thought too.

You could also make a copy of the feature class and build a model in ModelBuilder with the Iterate Feature Selection iterator (https://doc.esri.com/en/arcgis-pro/latest/tool-reference/modelbuilder-toolbox/iterate-feature-select... to go through each point, select by location the points in the other layer within some distance, calculate some summary stats, maybe run the Points to Line tool (https://doc.esri.com/en/arcgis-pro/latest/tool-reference/data-management/points-to-line.html?tabs=di....

Bob:

And thanks to you too! I've not yet tried it but it makes sense as an approach. I'll see what I can do... .
