[Geoserver-users] Image Order in a Mosaic

Gobstopper · March 17, 2008, 7:37pm

Hello,

I have several geostationary satellite images that cover different parts of
the earth.
https://www2.metnet.navy.mil/TESI0/examples/satimagery.tgz
1) GOES East GeoTIFF. (-110.99, -16.03) (-28.97, 65.99)
2) GOES West GeoTIFF. (-196.75, -16.03) (-85.21, 65.99)
3) Full GeoTIFF. (-179.95, -89.95) (179.95, 89.95)

I have been able to successfully mosaic the east and west images, as well as
successfully mosaic the full and west images.

I've used the MosaicIndexBuilder as well as built the mosaics by hand using
gdaltindex and the tutorial here:
http://docs.codehaus.org/display/GEOSDOC/Using+the+ImageMosaic+plugin.

The issue is, GeoServer (gdaltindex/MosaicIndexBuilder?) always puts the
full image on top of the other images. When mosaicing east and west, east is
always on top. I've done every permutation of different input orders with
gdaltindex/MosaicIndexBuilder, to no avail. The full image is always on top.

I'm looking for a way to choose the order of images to be mosaiced, so I can
lay these GOES images on top of the full image.

Thanks,
-Sam

Hi Sam:

I don't think it was something I did knowingly.
The rasters in the tutorial are generated from satellite passes and
have the date and time appended at the end of the file name. So
earlier passes appear *under* later ones. Just an idea, I am not 100%
certain at the moment if this is true. But it is the explanation I
have for now.

Have you tried placing the entry for the full image at the top of the
table associated with the index shape file?

Hi Alex,

It was a workaround that was considered, but in the end we decided not to go with. We're going to have a large amount of satellite imagery coming in consistently, and would like to integrate each in with a mosaic.

I'm essentially trying to duplicate your tutorial, how did you get to decide the order of the images in the final product i.e. the two satellite swaths and the U.S. map on top?

Thanks,
-Sam

Would it be acceptable to configure the full image as a separate
layer, and then request it before the mosaic layer in your map?

Ciao Samuel,
the imagemosaic does not really provide an easy way to decide the
order in which do overlay the images.
When I wrote it I had in mind simple cases with limited overlap, it
was not really designed to handle more complex cases.

I have given some thoughts on how to be able to control the order of
the images (I'd need it for fully supporting LSD RasterSymbolizer 1.0
btw), but so far I never had the time
to implement something. If you can provide 3 or 4 sample images I can
try (but I can't promise ) to do some experiments to see if I can
find a quick way to allow people to configure the
order of the resulting images.

Hi Alex,

I've tried every permutation of order when it comes to ordering by filename,
to no avail. Also, changing the table order has no effect...

Thanks,

Hum, can't you just configure the "big" one as a separate layer,
and then do a getMap request like layers=bigOne,mosaic?

This would enforce the order you're looking for

Simone, what about sorting tiles by name?
Should be quite easy to do, if the order does not pleases you,
you just rename files as 001_tile.tif, 002_tile.tif and recreate
the index file.

Cheers
Andrea
