[Geoserver-users] Raster Questions

GeoServer GeoServer User
1

I’ve been evaluating GeoServer for a data warehouse sort of application, and it looks very good. I have a couple of questions, that I couldn’t quite figure out.

We need to be able to serve a large amount (>20TB) of raster data, quickly out to Google Earth, as well as out to WMS clients. GE is the most important, and it looks like GeoWebcache with the GE Super Overlays might do the trick with the least amount of work. However, currently the base imagery is in a variety of formats and projections.

Do you think that we should standardize on a particular format and projection for the base imagery, or will GDAL-ext with GeoWebCache with Super overlays do enough speed up without having to do this?

Or should we put everything into a big tile pyramid?

Thanks,
Roger

Dear Roger,
first of all thanks for the compliments, it is always nice to see your
(well, there is a community behind this anyway..) work appreciated!

Let go back to your enquiry. In principle, I would say that it would
be nice to know a bit more about the formats and projection of the
data you are trying to serve, however I can give a few suggestions.

1> If using GE is your main objective, I would prepare your data
carefully before publishing it. As an instance, GE uses WGS84 hence I
would avoid making GeoServer reproject the data for you, I would
rather prepare them first with overviews and everything (if
applicable) and then let GeoServer and GeoWebCache do their thing
together.

2> For WMS, check first if your projections are supported by
GeoWebCache. If not have really high throughput with such an amunt of
heterogeneous raster data, I would suggest to do a bit of development
and move tha caching mechanism inside the server to work on the native
data, prior to any possible reprojection. This is something that is
not implemented right now but it has been on my radar for a while and
could be summarised as "adapt GeoWebCache backend to work for generic
raster data".

About imageio-ext, since gdal is about to release 1.5.3 (which we were
waiting for) we should move it into supported status quite soon, which
would mean support for formats like bigtiff and erdas imagein (and ecw
and mrsid and jpeg2k, etc...). Which could come handy in serving large
amount of data.

I think I have provided some information to discuss furter, therefore
I will just wait for your feedabck, to dig further.

Simone.

Is reprojecting a lot of processing power Simone? I mean, once everything gets through geowebcache then it shouldn't matter if the backend is in different projections and not prepared, no? The only issue is when building the cache, and I could definitely see it being faster to do one big process of overviews and reprojection. But if GS doing reprojection on its own is decently fast then it might be easier to skip the processing step and just build the cache in GWC iteratively, as people request things, no? Because there could be large areas of the rasters that are not used for awhile, so the cache could build up slowly.

2> For WMS, check first if your projections are supported by
GeoWebCache.

Note that for 1.0 GWC should support all projections. Not sure if the latest release has it in, and if it is it's probably not documented yet. But when Arne returns from vacation 1.0 should get out pretty soon.

If not have really high throughput with such an amunt of
heterogeneous raster data, I would suggest to do a bit of development
and move tha caching mechanism inside the server to work on the native
data, prior to any possible reprojection. This is something that is
not implemented right now but it has been on my radar for a while and

Interesting, I'd like to hear more about this. Maybe send your ideas to GWC list Simone?

Dear Chris (and anyone else with an opinion!),

I need just a bit of sales help here - its going to be an uphill battle to get GeoServer accepted for this project, as the powers that be are not Java friendly. (Lots of Mapserver experience, and seem to like the idea of MapGuide as well) Can you possibly give me some reasons to propose GeoServer vs MapServer and MapGuide OS? Our requirements are:

KML Super Overlays for GE, vector and raster
WMS
WFS-T
WCS
Standard Metadata and Cataloging
Layer level security access permissions

We will be running several Win 2003 server x64 servers with big drives. Performance is important. Professional support available. We also don’t have much time to get the whole thing up.

KML Super Overlays for GE, vector and raster

Check for vector, don't know for raster, but someone could add that
as part of a sponsored work (see commercial support below).

WMS

Check, with full SLD support.

WFS-T

Well, this is the deal breaker I guess. MapServer does not support
WFS-T, don't know about MapGuide. GeoServer is also reference
implementation for WFS.

WCS

Check, and reference implementation here too (for WCS 1.1)

Standard Metadata and Cataloging

None of the above support that, we usually recommend pairing up
with GeoNetwork (which is the reference implementation for OGC
catalog, and coded in Java as well).

Layer level security access permissions

GeoServer has this built in since 1.7.0, MapServer does not, you
have to code it, MapGuide, don't know.

We will be running several Win 2003 server x64 servers with big drives. Performance is important.

Rumor is that MapGuide is slow. Properly configured GeoServer is
faster than MapServer in various cases, see here:
http://files.opengeo.org/presentations/WebMapServerPerformance-FOSS4G2008.pdf

If you have time to build a case, you can also try benchmarking
MapGuide using the same scripts and data I used for that presentation,
they are here:

If I look at your requirements, some of them simply cannot be filled with
Mapserver out of the box. E.g. WFS transactional. Also the KML support is
only possible with another product on top
(http://www.itopen.it/soluzioni/kml-map-server/), and I doubt they support
super overlays. Layer level security is also hard to do with Mapserver
right now (you probably need to write your own OWS Mapscript service).

So basically your requirements make the choice easy.

Bart

This is what drew me to GeoServer in the first place plus the performance charts in

http://files.opengeo.org/presentations/WebMapServerPerformance-FOSS4G2008.pdf

with PostGIS probably will clinch the deal in favor of GeoServer. Now if I can just grok the whole KML Super Overlay - GeoWebCache big raster thing for Google Earth, I may be done.

At this point in time (which is all I have), MapGuide OS doesn’t seem to cut it either, from this thread dated Oct. 17 2008:

http://n2.nabble.com/Supported-WMS-and-WFS-in-MapGuide-td1331826.html

“Server: WMS 1.1.1, WFS 1.0.0 (WFS is unstable ATM)
Client: WMS 1.3.0, WFS 1.0.0
There is no WFS-T support.
OGC certification has not been done since MGE 2007, but the code is largely unchanged.”

I think we’ll be going with GeoServer.

GeoServer already supports raster superoverlays in KML; in fact we have a nice writeup on the wiki about using a tile cache to improve raster performance. http://geoserver.org/display/GEOSDOC/03-Super+Overlays+and+TileCache

Hope this helps!

Raster Super Overlays were actually so easy to implement that I guess few in our community really know that they're there. They're all done through GeoWebCache, which is integrated with GeoServer, and will be more so in the future. See http://geowebcache.org/trac/wiki/google_earth You can reuse the same cached tiles for Openlayers maps in 4326 as well.

I don't believe MapGuide supports vector super overlays. You can see some of our demos of the vector super overlays at http://projects.opengeo.org/geosearch/wiki/layerlist and more are coming soon. We also allow you to publish these to Google Maps, so users can potentially find your data that way, see for example: http://tinyurl.com/5fdbwy

Last I checked MapGuide didn't do WFS-T, and MapServer has no plans to. Note we're also pushing the bounds with WFS-T, adding 'versioning' on top of it to do history, diff, and rollback. A couple demos are at http://demo.opengeo.org/nymap/ (though rollback's not working right now) and http://design.livablestreets.com/maps/ (guest / guest5 if you want to try out transactions).

Not sure if you're going to also do a nice front end, but if you want something to show we've been working on an ArcIMS replacement app, see http://geoext.opengeo.org/alachua/trunk/demo.html the old one is http://maps.alachuacounty.us/geopt/viewer.htm Ours is still under development, but should be pretty nice when done.

This is going to evolve to 'GeoExt', collaborating with Camptocamp, for a bunch of nice Ext.js integrations with OpenLayers. Another nice example of using Ext.js and OpenLayers, backed by GeoServer is http://maps.trimet.org/ It's running in production, TriMet is the main public transit agency of Portland.

We will be running several Win 2003 server x64 servers with big drives. Performance is important.

Rumor is that MapGuide is slow. Properly configured GeoServer is
faster than MapServer in various cases, see here:

If you have time to build a case, you can also try benchmarking

Ah, we _really_ need to change this page. Much, much better ways to do things now with GeoWebCache, which should be the recommended way. The info on that page was basically a proof of concept.

Mike/Ivan, could you prioritize updating this page? It should basically point users to GeoWebCache plug-in installation and the GWC page on Super Overlays, with hints on where that url is if it's part of GeoServer.

Chris,
This all sounds very awesome, I’ll be hunkering down this week and getting some demos out for our team, so I may be pinging the list for help at times.

Of course, there is always “something”. My team leader just asked me:

"has there been any work
in the OS community related to providing ESRI map services (e.g. ESRI
Image / Feature services)? "

What ESRI Image / Feature services are is way beyond me. Perhaps someone could shed some light on this for me - is this even possible in an OS environment?

KML Super Overlays for GE, vector and raster

Check for vector, don’t know for raster, but someone could add that

Raster Super Overlays were actually so easy to implement that I guess
few in our community really know that they’re there. They’re all done
through GeoWebCache, which is integrated with GeoServer, and will be
more so in the future. See
http://geowebcache.org/trac/wiki/google_earth You can reuse the same
cached tiles for Openlayers maps in 4326 as well.

I don’t believe MapGuide supports vector super overlays. You can see
some of our demos of the vector super overlays at
http://projects.opengeo.org/geosearch/wiki/layerlist and more are coming
soon. We also allow you to publish these to Google Maps, so users can
potentially find your data that way, see for example:
http://tinyurl.com/5fdbwy

Last I checked MapGuide didn’t do WFS-T, and MapServer has no plans to.
Note we’re also pushing the bounds with WFS-T, adding ‘versioning’ on
top of it to do history, diff, and rollback. A couple demos are at
http://demo.opengeo.org/nymap/ (though rollback’s not working right now)
and http://design.livablestreets.com/maps/ (guest / guest5 if you want
to try out transactions).

Not sure if you’re going to also do a nice front end, but if you want
something to show we’ve been working on an ArcIMS replacement app, see
http://geoext.opengeo.org/alachua/trunk/demo.html the old one is
http://maps.alachuacounty.us/geopt/viewer.htm Ours is still under
development, but should be pretty nice when done.

This is going to evolve to ‘GeoExt’, collaborating with Camptocamp, for
a bunch of nice Ext.js integrations with OpenLayers. Another nice
example of using Ext.js and OpenLayers, backed by GeoServer is
http://maps.trimet.org/ It’s running in production, TriMet is the main
public transit agency of Portland.

Chris

What ESRI Image / Feature services are is way beyond me. Perhaps someone could shed some light on this for me - is this even possible in an OS environment?

You mean like having it emulate ArcIMS or ArcGIS server and speak their language? Years ago Refractions worked on what I guess is called IMSEMU http://mapserver.refractions.net/mailman/listinfo/imsemu-devel to make MapServer emulate ArcIMS

So it’s possible, at least with ArcIMS. Not sure if anyone’s figured out the protocols for ArcGIS server. But basically, it’s theoretically possible, it’s just a matter of teaching the language to the OS product. It’d need some funding to do it in GeoServer.

Hi,

yeah, the geowebcache.org's Google Earth page is too complicated, and the one you're looking at is the old TileCache page. New documentation has been held up by my vacation, will be fixed as soon as I can get rid of some idiosyncrasies that take longer to explain than to fix.

Try
http://localhost/geoserver/gwc/service/kml/topp:states.png.kml
or
http://localhost/geoserver/gwc/service/kml/topp:states.jpeg.kml
replacing topp:states with the name of your layer.

Both should work out of the box for the plugin, let me know what you find ? (I haven't had a chance to test 1.7.0 myself)

Cheers,

Arne,
Well that was sure easy, works like a charm. I was confused with all the other examples. Now I’m very happy I chose GeoServer with GeoWebCache!

Hope you had a good vacation, and the glow stays with you for a while.

GeoServer already supports raster superoverlays in KML; in fact we have
a nice writeup on the wiki about using a tile cache to improve raster
performance.

Hope this helps!

Dear Chris (and anyone else with an opinion!),

I need just a bit of sales help here - its going to be an uphill
battle
to get GeoServer accepted for this project, as the powers that be are
not Java friendly. (Lots of Mapserver experience, and seem to like the
idea of MapGuide as well) Can you possibly give me some reasons
to propose GeoServer vs MapServer and MapGuide OS? Our
requirements are:

KML Super Overlays for GE, vector and raster

Check for vector, don’t know for raster, but someone could add that
as part of a sponsored work (see commercial support below).

As I already confirmed that is on the radar for us, hence we would be
willing to provide help for this as well as in general for raster
preparation and preprocessing.

WMS

Check, with full SLD support.

I would add also that there exists capabilitie to use vendor
paramters in order to customize and fine tune the rendering,
see http://geoserver.org/display/GEOSDOC/WMS+vendor+parameters.

Regards,
Simone.

WFS-T

Well, this is the deal breaker I guess. MapServer does not support
WFS-T, don’t know about MapGuide. GeoServer is also reference
implementation for WFS.

WCS

Check, and reference implementation here too (for WCS 1.1)

Standard Metadata and Cataloging

None of the above support that, we usually recommend pairing up
with GeoNetwork (which is the reference implementation for OGC
catalog, and coded in Java as well).

Layer level security access permissions

GeoServer has this built in since 1.7.0, MapServer does not, you
have to code it, MapGuide, don’t know.

We will be running several Win 2003 server x64 servers with big
drives.
Performance is important.

Rumor is that MapGuide is slow. Properly configured GeoServer is
faster than MapServer in various cases, see here:

http://files.opengeo.org/presentations/WebMapServerPerformance-FOSS4G2008.pdf

If you have time to build a case, you can also try benchmarking
MapGuide using the same scripts and data I used for that presentation,
they are here:

http://files.opengeo.org/presentations/foss4g-benchmarks-data-scripts.tar.bz2

Professional support available.

Check, see here:
