i have a cluster of points in particular areas around NZ.

I am only wanting the point with the highest value in this cluster to remain. Also many of the points have the same value, i am just wanting 1 point in the cluster to remain. It does not matter which highest point it is, as long as it is one with the highest value.

Any idea on how to do this?

Bottom pic is using focal stats > raster calc and then raster to point enter image description here

Not the best solution in your related post. Use focal statistics (maximum) for neigbourhood of your choice, e.g. 500*500 cells, output - raster, called FC. Use raster calculator to locate highest points:

Con ("DEM">="FC","DEM")

Convert output raster to points, e.g.: enter image description here

  • Thanks, i just tried this. Works, and agreed better solution then mine. However my end result is still multiple points but with the same value, i still need just 1 point in each area? @FelixIP i posted picture up top – Vanessa Sep 17 '20 at 6:31
  • Just increase search raster in focal statistics. Your dem is faulty, because groups of points indicate completely flat large area. – FelixIP Sep 17 '20 at 7:31
  • I meant massive flat top mountains, good luck to find them in nz – FelixIP Sep 17 '20 at 7:37
  • My raster isn't a DEM - its not showing heights. – Vanessa Sep 17 '20 at 23:44
  • Ok. Change to Con ("DEM">="FC",1), region group and do zonal geometry as table. – FelixIP Sep 17 '20 at 23:54
