Dear List Members,

I am completely new to geotools.


I have gridded raster data (population) in a GeoTiff.

I can get the grid value for a certain longitude/latitude with geotools.
Fine.

But how can I get the summarized value of all grid cells within a given
distance around a given point ?

(I know that it will not be a real circle, more a polygon depending on
the grid cells' size.)

I would be thankful if someone could give some ideas. I did read the
tutorials. But nothing matched.

Thank you!

Peter
