Dear geotoolers,
I would like to apply a neighbourhood sum operation on a coverage (ie.
like focalsum in esri parlance) using (a) a circular mask and (b) an
arbitrary but spatially contiguous neighbourhood.
I'm sure it iust be simple to create a mask and move it over the
coverage but I've become
I will quickly reply since this is a fun topic ... sure wish I had time
to work on this stuff.

I was more asking if you have any sort of dynamic styles, Rules,
Expressions and
Actually, i think that is rather easy to do. You just take a circle,
and reproject it into your coordinate system. The radius of the circle
is the earth radius, and the middlepoint is the position on the earth
where the sun is in the zenith for that moment.
The only thing you need is the position

The valid value range and no data values for the data that I'm using
appear to be stored only in GDAL-specific tags, so the GeoTiffReader is
not picking them up as such. Thanks for the help, though.
Is there any work being done on an HDF or HDF-EOS Reader? That's where

If the GridCoverage2D has been constructed with SampleDimensions (I don't know
if our
Is there a way to get fill value/no data value metadata and similar items
from a GridCoverage2D object? I know that this is not always available, but
it'd be nice to get when it is.

Anybody ever had an attempt in drawing the night area of the planet ?
I'm trying to figure out a simple way, based on a timestamp, to darken the area
of the map representing the night. Preferably using vector data so I can check
whether it's day/night on a certain point on the planet.

Thanks Jan, that seems to work to calculate the points in the circle.
Using GeodeticCalculator, the setDistance takes a 'distance' parameter. I
want to set this in KM, but am not sure if any conversion is necessary.

I have a (large) graph in which the Node attributes are 3d coordinates.
For Nodes A and B, the edge weighting I want to use is a function of the
slope (i.e. Z coord difference) between A and B.
Is it possible to achieve this without having to create a directed graph

Hello Cliff,
In the case of a geodetic reference system (ie WGS84) if I'm not mistaken there
is a utility class to do the apply the same solution: GeodeticCalculator. I
never used it, but looking to the api it's what you need.
1) Instantiate this class with WGS84.
2) set the center point: setSt
