Sorry, I slipped back into 9x map algebra.
Here's a raster calculator syntax
("inraster" == FocalStatistics("inraster","#","MAXIMUM")) and
("inraster" > FocalStatistics("inraster","#","MINIMUM"))
Using a larger-than-default neighborhood may help you find broader "domes" that have some flat areas on the top. These areas could then be collapsed to single-cells or points using the Zonal Geometry tool with the CENTROID option.
This will select areas where the center cell is the equal to or greater than the maximum of the neighborhood, as long as the whole neighborhood is not the same value (flat).
Okay, I get some idea of what you´re heading for and the syntax. I tried it but it failed:dtm20=> my raster-data, # = neighboorhood settings?("dtm20" == FocalStatistics("dtm20","5","MAXIMUM")) and
("dtm20" > FocalStatistics("dtm20","5","MINIMUM"))
maybe a short explanation how to implement the code? Or maybe running "focal statistics" first, before some "raster calculator"?Thanks a lot for your help
