IF YOU ARE INTERESTED IN GRID COVERAGES OR THINK GRID COVERAGE WORK WILL
AFFECT YOU - PLEASE SPEAK UP NOW.
We didnt have enough time to discuss all the details, so we're having
another meeting next week. Also, we've been discussing merging in the
Grid Coverage renderer to trunk, which could affect the FM folks.

Please see the meeting logs (
http://docs.codehaus.org/display/GEOTOOLS/2006/05/01/Renderer+IRC ).
Folks are interested in merging in the Grid Coverage Branch. The timing
may be in conflict with the FM merge (see other message)
Simone and Alessio can give some detail about what going on in the
branch, and what needs to be done to bring it on to trunk. I,
unfortunately, dont know anything about the branch. I believe they they
will be ready with 2d grids next month and 5D grids "soon" (and is dealt
within the branch's current structure). Their branch is currently
nicely aligned with whats in geotools so there shouldnt be a problem
with merging. The outstanding issues are concerned with the Streaming
Renderer.
Here's a meeting outline (feel free to modify):
a) Simone and Alessio will talk about what needs to be done on the
GridCoverage branch and when it will be ready to merge in to geotools
trunk. There's a lot of functionality there, and they will also talk
about how this will affect current users and developers so there is a
smooth transition.
b) Streaming Renderer Issues:
1. CRS. It appears that if we use a ReferencedEnvelope a bit
differently than we are now, the Streaming Renderer will be functioning
"according to spec" and work with the GridCoverage stuff.
Unfortunately, many people do not make requests to the renderer
"according to spec" so we may need some "hints" that says "renderer
according to spec" or "renderer according to what everyone actually
does". Hopefully Martin (and Frank W) will (hopefully) have something
to say about this. S&A already have it working, so its mostly a case of
seeing how it affect folks and making sure its "properly" done.
2. Interaction with the Grid Coverage Renderer. Simone and Alessio
said this is "easy" and already have something simple.
c) Java GDAL bindings
There are several java folks interested in getting GDAL working well
in JAVA. FrankW said that GDAL is moving more towards having
thread-safe read-only access to rasters. Simone and Alessio also
mentioned that making GDAL working will with JAI/geotools would also be
a big win. Not sure what the timeframe is for this, but I think "3
months" was mentioned. Its not a "needed" component for Grid Coverage
support -- it just open up the possibility of interaction with GDAL. If
you're interested in this, or know someone who is, please let them know
so everyone can work together.
I have a *little* time to donate to this. I dont know anything about the
Grid Coverage branch, but I do know about the Streaming Renderer and
willing to help out there. Who else has some time to help with this?
Even if its just kicking the tires...
I'm looking forward to seeing the Grid Coverage stuff come onto branch,
because its the first step in getting the WCS/WMS-with-raster support in
Geoserver's trunk. I also know there are several other people who want
Coverage support in geotools.
Please send your thoughs, and join us next week at the meeting.
