[Geoserver-users] Downloading underlying coverage data

Hi,

Is there a way to get GeoServer to serve up the image data backing a coverage store? It would really be slick if my users could download just the subset that is displayed in an OpenLayers map (e.g., if they zoomed in, they would be able to get an image containing only the data within the current zoom extents.

Thanks!

Greg

Ciao Greg,
I think that depending on the type of data we are talking about,
either WMS or WCS is your friend. As I said, I would need more info
about your data. If you are serving rgb images, you can go with WMS,
if you are serving raw imagery ans styling it on the fly then you need
to use WCS. However, given that rastersymbolizer is pretty new on the
GeoServer scene, I believe that WMS is what you need.

Simone.

Hi Simone,

The backing data stores will be heterogeneous. Right now, I am using GeoTIFFs and World Image files. In December, I will implement an ImageIO-Ext/GDAL extension to handle Arc/Info binary grid data. Can you point me to some example showing how to format the URLs to retrieve these data (or subsets)?

Thanks!

Ciao Greg,
if you plan to serve heterogeneous sources of data then you need to
resort to WCS.
Btw, FYI, we have already added read support to binary arcgrid inside
imageio-ext and I will add read support for it in the relevant
geotools plugin shortly. We are going to bring imageio-ext in to
supported land quite soon since finally gdal 1.5.3 is being released
8we were waiting on it for a few fixes).

About the samples, you should find some in the smaple requests and/or
in docs and/or in testcases.

Simone.

Hi, Simone,

That’s fantastic news about binary arcgrid support!

I’ll take a look at the examples you suggest.

Thanks!

Ciao Greg,
actually, Daniele was asking me if I could find some test data.
I think I can pass the questio over to you :-).

Simone.

Hi Simone and Daniele,

Yes, definitely. I am developing an application for EROS, and they gave me some test data. It isn’t much, but I can get more if you need it. I’ve staged what I have for you:

Cheers,

Greg

Hi,

Has there been any progress on bringing Arc/Info binary grid format to GeoServer?

Thanks!
