I have a bathymetric raster from which I want to extract the max depth value within a mask (vector) layer. The vector layer has 252 circular polygons The end result must have x, y and depth attributes
I tried the zonal statistics function, but this function only adds the max value and not the x and y coordinates
I have added a screen shot of what I actually want:
I have a one raster (north sea bathymetry) containing 63 locations. (In the screenshot only a few locations are shown.) At each location a jack-up barge (which has 4 legs hitting the seabed) is positioned. The center xy coordinates of the legs are known (I have a CSV) I created a delimited layer of all these coordinates (CSV). Then I made a circular buffer around all coordinates, which represents the footprint of the legs.
Now what I want is to get the Max value (x,y depth) of the raster within each circle and store the values in a point file. This point file should have 63 x 4 =252 records.
I also need this for the Min value
