[Geoserver-users] Serving hundreds of contiguous image maps

Hi all, I have hundreds of compressed geotiffs that are contiguous, and would
like to serve them in geoserver's wms. How do I do this so that the user
only has to specify the coordinates, and not all the layer names?

I tried imagemosaic but didn't get too far because I don't think it works
with compressed geotiffs...?

Any ideas would be appreciated. Thanks a lot!

I think it does, at least for packbit-compressed images (mine, for instance). Which error messages are you receiving ?

Ciao kevin,
imagemosaic should work with compressed geotiff files. I usually use
jpeg-in-tiff or lzw compression myself.

I'd suggest you to report in more detail what you want to achieve,
what you have done in order to achieve your goals with geoserver, and
what error you experienced, otherwise it won't be possible to help you
out.

Ciao,
Simone.

Thank you both. You're right, it does work. I was doing something wrong the
whole time, and thought that it was imagemosaic's inability to handle
compressed geotiffs. Since you confirmed that it does work, I tried it
again and found my mistake, and it works :slight_smile: Thanks a lot!

Ciao kevin,
good to knoe everything worked out.

It would be probably good to have some more info about what you did so
that people in the future won't do the same error or if they do they
will find the solution in the ml.

Ciao,
Simone.

Ah yeah, I was basically using the tutorial here:

http://docs.codehaus.org/display/GEOSDOC/Using+the+ImageMosaic+plugin

and doing the "dgal" method. But since the images are compressed, the pixel
sizes were really small, like 0.00005004 or something, instead of the
10000.0 in the example, so I thought there was something wrong. Also, I was
using the wrong envelope. I think I put upper right corner first, and then
bottom left.

But after fixing that, it worked just fine :slight_smile:
