How do I figure out elevation statistics around each point?

JayurMehta — Wed, 28 Jun 2017 18:48:06 GMT

Hi! I would like to obtain some data from the image above - I would like to know the distribution of elevations around each of the black triangles shown above - perhaps within a radius of 15 meters of each point?

Can anyone help me figure out how to do this? I particularly want to know the highest elevations, the lowest elevations, the avg. elevation, and modal elevations around each of these points.

buffer the points by 15 meters, then you can use

zonal-statistics-as-table

and here is how it works

Thanks Dan! Can you please also tell me how to buffer each of my points by 15 meters?

Yes, you use the Buffer tool in Arctoolbox but you want to make sure you are using projected data or you have your data in a projected data frame to ensure that your buffer distances are in meters and not in decimal degrees.

you could also use Focal Statistics
