I have a series of 30m buffers along a polyline (river). Within each buffer I have a series of points each point represents a 10m x 10m cell with an elevation value known as "Elev".

I want to find the one point with the minimum elev value within each buffer and output it as a point file. In a future geoprocessing set I'll like to snap this point back to the river.

ArcGIS 10.1, arcinfo license.

I created a custom Calculate Point Statistics toolbox that basically does this. It loops through each polygon feature and finds the minimum, maximum, and average of the points within each polygon. However, instead of outputting the results to a point feature, it adds them to the polygon feature.

You could pretty easily change the script to do what you want.

  • Thank you Ian. I should easily be able to change your script to meet my needs. Thanks again.
