Hi Steve,
No need to apologize - there is no chance that you are less organised
or more frequently late than me.
Thanks very much for the info - great news about it running with 1.5.
I'm doing a checkout of your code as I type and I'll try it out
shortly. By the way, there is a certificate warn

I've got geotools / maven cooking with Netbeans 6.
Firstly, I'd recommend that you update your Netbeans from 5 to 6.
There are quite a lot of bug fixes and some useful new features
including a local and remote maven repository browser and better
support for subversion, and smart editing of the ma
That is very old; it seems that netbeans users have not contributed
documentation recently ...
I would follow the instructions for eclipse...where they say: mvn
eclipse:eclipse use "mvn netbeans:netbeans" and hope for the best.

Hi Michael
Sorry for answering so late.. Yes.. i think you can build the AtlasStyler with
1.5.. (In my build.xml i use source and target = 1.5 and it seems to work)
i have release all code as LGPL and moved it to a public SVN last weekend. I
will probably send a "bigger" announcement onto this
Hi;
I have just began looking at GeoTools as a possible way to enhance a
landscape modelling framework that we are working on. Currently we are
using matrices to hold raster data (which is usually not imagery), with
limited spatial referencing. By using GeoTools we are hoping to make it

Jody,
thanks for response.

yes

Michael,
I allready had a look at JAI (ROIShape etc.). I got stucked, thus I
ended up trying something else.
Well I think I have to review the ROIShape-stuff and dig a little
bit deeper.

No worries :)
I think you can use one of JAI's iterator factory classes to create an
iterator that only looks within a mask area. And you can create a
mask with the ROIShape class from your polygon. I'm definitely not a
JAI expert but I think if you have a look at the JAI docs you should
find wh
Sorry for the unprecise question.
My underlying question is which pixels of a grid are "inside" a
polygon (ROI).
Therefor I want to derive points from the pixels and afterwards check
which points the polygon contains.
The latter can easily be done by JTS: polygon.contains(Point). But I

yes - Martin's code is assuming that you've got a rectangle expressed
in screen coords - is that what you're starting with ? (sorry - it's a
bit ambiguous in your query)

It converts a Rectangle from pixel coordinates (in coverage image) to
geographic
coordinates (in coverage CRS). I though that this is what you wanted to do...
Thanks Martin,
but...unfortunately...I...erm...don't get it...
What exacly is your code doing?
"Rectangle pixelBounds" is the bounding box of the polygon?
What is "CRS" in the third line - the CRS of the grid coverage? The
transform-method is undefined for

Hi list,
given a GridCoverage2D and a rectangle (derived from the bouning box
of a polygon), what is the best way to get the world/geographic
coordinates of the pixels the rectangle contains?
I think about a two step process:
1. Crop the grid to the rectangle.
2. Calculate the world coordina
