Use tool to get a polygon from points ?

DEAF_PROBERT_68

Hi, I am looking for a tool either in ArcGIS Pro or FME , I have this points that has all the information I have .

This layer came from CAD person and did digitize in points. They have all the same attributes . What I need to get all the points in grouping.

Here is an example of the points. It is a campground. Points to Polygon.jpg

What I want is to get the points turn into a polygon of the same attributes.

I tried using Envelope to Polygon but it doesn't take points. So I had to use dissolve and then use it.

Is there another way around to do this ?

convex hull in Minimum Bounding Geometry (Data Management)—ArcGIS Pro | Documentation

assuming that you just want one polygon representing the approximate bounding area, otherwise you need to explain any other grouping that needs to be done

You might also run it through https://pro.arcgis.com/en/pro-app/latest/tool-reference/cartography/smooth-polygon.htm too... just to make it look a little nicer. Maybe even buffer that polygon outside a bit too. The points are an approximation, and probably don't represent the furthest location from the road... so you've got some latitude as a cartographer to make the outline look good too. But definitely start with the tool @DanPatterson pointed you to.

There is also Dan's very cool Concave Hull toolbox if you want a tighter polygon.

Thank you ! I realized that the picture I first show you should have been like this. The one I show you is one small zoom into small area... My bad.

But I have a question, should I create a polygon around it and then run the concave hull inside the polygon ? or is there a better tool for that ?

DanPatterson

You could do a convex hull as a first approximation using the Minimum Bounding Geometry tools

to see what it looks like first. If you want to get a tighter approximation try the concave hull with the points as the input. Concave Hulls require points as input.
