[Geoserver-users] GeoServer, NetCDF, PostGIS in 4D?

Samuel_Hiatt · October 9, 2007, 12:21am

Unfortunately I missed Martin and Mickael’s presentation at the FOSS4G, but it looks like they are working on solving the same problem that I am faced with - that of presenting archives of spatio-temporal raster data via GeoServer.

Right now I am specifically interested in learning how to get GeoServer to communicate with PostGIS to get the data that is referenced by a WMS request. I have not been able to find documentation that addresses either of the following issues:

Configuring GeoServer to serve raster data by consulting a “tile index” shapefile that points to the necessary raster (as you would do with Mapserver).
Configuring GeoServer to accept TIME-specific W*S requests.

Can anyone point me somewhere that might help me figure this out?

Thanks!

Sam

Hi Samuel,

Currently we don't support tile indexes for vector data like mapserver
does. However for raster data there is the image mosaik plugin.

As for WMS with time, support is quite limited. You can specify the TIME
parameter in a WMS request but it only works with netcdf, and only
accepts a simple integer timestamp format.

Yep, mosaic is what you're looking for.

Soon to be changed to accept a real ISO time when I'll handle:

Thanks for the reply…

I will take a look at the image mosaik plugin. It might be what I am looking for.

Could you explain the architecture of how one would set up WMS with time reading data from NetCDF? I imagine you’d need the non-standard GeoTools plugin to read the NetCDF?

Are you referring to the work that the IFREMER/Geomatys guys are doing?

Thanks.

Yes, there is no standard netcdf plugin around. The work done by the
Geomatys people should land by the end of the year, not sure how to
handle netcdf in the meantime.

That is what we use at the moment--the integer indexing for TIME is my fault

You would need the netcdf plugin as well as the necessary java netcdf
classes for reading.

Hi all,

NetCDF Reader is in Geotools/Unsuported. I think Martin has comited the ImageReader Framework too on this repository.

About PostGRID datastore, we will start this job ASAP but before, we have to work on the CoverageReader, because currently, when we're zooming on the NetCDF image, it sill load the whole image instead of loading the subset only.

Hi,

We have Geoserver 1.6.0-beta3 running on a PostGIS database.
We have the following problem with Geoserver 1.6.0-beta3:

While doing a WFS update, we get an exception (see xml at the bottom of this
mail).
The xml we're sending to Geoserver is:

The software used to work with Geoserver 1.5.3, but since we've upgraded to
1.6.0-beta3 and WFS1.1 we are unable to update a record in our PostGIS
database.

Does anybody know how we can fix this?

With kind regards,

Lex Tiekink

Hum, strange. Can you try doing the same update without this "boundedBy"
property update? BoundedBy is computed on the fly and it's not really
in the internal type schema we use for data, it's something we make up
during GML generation.

Let me know if this fixes the problem (otherwise we'll need to have
a good look at the other properties, what I gather from the exception
is that there is one of those properties that is recognized by
the xml parser but not by our internal feature model, resulting in
an element of attributetype array which is null, thus the npe).

Cheers

You also might try to use WFS 1.0 on 1.6.0-beta3, as it has more of the same code from 1.5.3.

Only in the encoding part. The incoming request parsing is managed by the new parser.

Lex_Tiekink · October 11, 2007, 8:09am

After some expirimenting, I found that the gml:boundedBy should indeed be
removed from the xml, as was suggested by Andrea.
Also, the <gml:posList> does not work, while the <gml:coordinates> does
work, even in WFS 1.1.
I'm now parsing the xml and replacing the posList tags by coordinates tags,
but of course this is not the optimal solution.

What could be wrong with the <posList> tag?

Hi Lex,

In gml3 "coordinates" has been deprecated and replaced with "posList".
However I thought I recently handled this case but perhaps not, You are
correct in that coordinates should be excepted even though they are
deprecated.

As for the boundedBy element, I believe it is a bug to throw an
exception when this value is present. I am scheduling a bug report for
these issues:

http://jira.codehaus.org/browse/GEOS-1394
http://jira.codehaus.org/browse/GEOS-1395

work, even in WFS 1.1.
I'm now parsing the xml and replacing the posList tags by coordinates tags,
but of course this is not the optimal solution.

What could be wrong with the <posList> tag?

Only in the encoding part. The incoming request parsing is managed by
the new parser.

Sigh, Andrea just pointed out that I read your email wrong. You stated
the opposite. Which confuses me because looking at the code it
definitely is supposed to be handling posList.

Regardless, I have the bug report so I will look into it soon.

Hi Lex,

In gml3 "coordinates" has been deprecated and replaced with "posList".
However I thought I recently handled this case but perhaps not, You are
correct in that coordinates should be excepted even though they are
deprecated.

As for the boundedBy element, I believe it is a bug to throw an
exception when this value is present. I am scheduling a bug report for
these issues:

http://jira.codehaus.org/browse/GEOS-1394
http://jira.codehaus.org/browse/GEOS-1395

After some expirimenting, I found that the gml:boundedBy should indeed be
removed from the xml, as was suggested by Andrea.
Also, the <gml:posList> does not work, while the <gml:coordinates> does
work, even in WFS 1.1.

but of course this is not the optimal solution.
