Hi Pedro,
I'm a Windows user at work. I do have a linux box at home that I use
occasionally. I found JUMP to be kind of buggy on my distro (MEPIS). I
hope to get a chance to work on this.
There is software called GeoExpress from Lizartech.com that converts
other raster formats to MrSID. It uses a by-the-megabyte license for
conversion from non-MrSID formats. My recollection is that it costs about
$1500 US per 100 gigabytes. It will take multiple rasters and create one
MrSID output file. It handles overlapping or non-overlapping rasters at
different resolutions per tile. It will also produce JPEG 2000 as output.
Since MrSID images include a user defined number of resolutions stored in a
pyramid, it is very efficient at all zoom levels.
Ok, sorry for the commercial. I don't own stock in Lizartech. MrSID is
just one of those ideas that I wish I'd thought of. :-]
About your 58MB shape file, I did agree earlier that it was at the edge
of OJ usability, didn't I? Oh, well, sometimes my enthusiasm gets the best
of me. I don't suppose you can reasonably break that shape file up into
areas without losing some usability, can you?
regards,
Larry

Larry,
I appreciate your input. Since I've been 'selling' OJ everywhere I can…
By now even hardened ArcGIS users here find OJ a viable alternative for
some kind of tasks… ;-)
Now, please tell me something: are you running OJ under Linux or Windows?
I mean, were this results obtained under Linux or Windows?
This was already posted earlier… but simply loading that 58MB shapefile
turns OJ into a **turtle**…
(this is a **very** detailed polygon layer for Portugal, mainland)
As far as MrSID goes… it's quite efficient. (btw: is there a
geotiff->mrsid converter?)
Regards,
Pedro.

Pedro,
It depends on your definition of serious work. I have personally used
JUMP with vector and raster datasets on the same order with good results.
Your problem is probably mostly due to the GeoTIFF, since that format is
inherently inefficient. With MrSID, I have used rasters that uncompressed
would be hundreds of gigabytes and it takes up no more memory than one
screen size. Of course, MrSID isn't free.
regards,
Larry

OMG.. I forgot to update this post..
The problem was on my side... with all the rush... I forgot to 'spatially
enable' the db...
Shame on me...
At this time everything is working quite well in OJ. (using nightly build
'openjump-20061203-0014')
Although it's more and more apparent that OJ isn't designed to manage
'serious' work...
For example:
A shapefile with only 58Mb and a GeoTiff ~230Mb simply blow OJ to
smithereens..
It usually disappears from the screen without even an exception caught...
And this in a wks with 4Gb of ram ... Xms1024M Xmx2048M
Now this can be caused either by Java or OJ...
Again my apologies for letting this post slip.

Pedro,
I've been doing a little work with the old PostGIS Driver worked on by
Uwe and Refractions Research. So I might be able to help.
Can you let me know how you are trying to connect to PostgreSQL from
JUMP. It appears that you are using the same plug-in from the stack
trace you pasted in your e-mail.
I remember looking at the PostGISConnection.executeUpdate() method, so
I am familiar with the code you are executing.
Please don't take offense, but when I read
"addgeometrycolumn("unknown", "unknown", "unknown", integer,
"unknown", integer) does not exist" in your error message, I almost
think that PostGIS isn't installed correctly.
This might not be a problem with OpenJUMP, but with the database or
PostgreSQL.
Have you sucessfully connected with the same data, database, and
command sequence using an older version of OpenJUMP?
