Dear Simone,
I will try to provide a case for JIRA, somewhere around Monday, no time
to do it before.
In the mean time - it is quite urgent for me to find a solution to pass
the GridCoverrage2D around - could you please elaborate how you would
serialize the coverage and consequently apply the
Another idea for a quick solution is to serialize a world file as well.
A world file has only 6 lines, see here
http://en.wikipedia.org/wiki/World_file
class TransportImage implements Serializable {
SerializabelRenderedImage theImage;
Double[] wordlFileLines;
}
That is all you need
Even better, if I could serialize a referenced envelope, which should be
serializable already, that would be a quick workaround.
So in principle I should be able to create a TransportImage as you
mention, with the two elements (Rendered Image, ReferencedEnvelope), and
then to decode it I will
Ciao MArtin,
serializing the envelope would not be generic enough, serializing the
grid world instead would be, at least for georectified raster data.
I'd would check the WorldFileReader class and the GeoTiffReader in
order to understand how to go from raster + world file to a GC2D.
Simone.
Thanks, Michael. Jody wrote back directly. I'll paste his reply here so
that it gets archived on the list for future reference.
G'Day.

Hi Simone,
thanks for that. Indeed, my preferred use would be to pass around a
serialized version of Geotiff - as mentioned.
I know how to go from Geotiff reader to coverage and back. But is it
possible to send a serialized version of a geotiff around? I have only

Hello !
I'm new to GeoTools.
I'd like to create an Geotiff image (and eventually reproject it before
saving) from a set of data composed of (lat, lon, value) values. The problem
is that these data don't represent a regular grid. Therefore, I don't know
whether I have to create a GridCoverage2D
Hello,
I am making an application where the user can retrieve information from a
feature by clicking on it.
To do this, I make a filter to get all features located on the area defined by
the projection on the map
of a 3x3 pixels square centered on the position of the click.
I encouter a
Hello Fred,
It depends on what you want your image and/or coverage to represent.
You probably need to be more specific about this so that people here
can suggest relevant approaches.
For instance, do you want a coverage / image showing values
interpolated from your irregularly distributed data ?
