Calculate a polygon/line that includes 5 % of my points

[FriederDaeublin]

Hi,

i am looking for a tool, similar to density, but that is noct exactly what I want.

I have approx. 140 Points that symbolize the sightings of bats.

Now I want ArcGIS to calculate the smallest area, that circumferences 5 % (or any other percentage) of the points (or the 95-Percentile).

Any suggestions?

Thanks

You can try using the Aggregate Tool in conjunction with the Feature to Line and Feature to Polygon tools to get an approximation of the area and see whether this gives you the 5% that you are looking for. It might make more sense to create a polygon that consists of all the points and then determine what 5% of that polygon looks like.

From there, you can use the aggregate tool to determine the approximate distance for a set of points to get you the 5%.
