It is essentially a web list of consultants and service organizations in the open source geospatial realm. We are currently seeking consultants and service organizations to register themselves in the directory. In a few weeks, assuming this goes fairly well, we will start trying to publicize the directory to potential clients, and work it into our presentations, materials at conferences and so forth. There is no cost to participate. You just need someone in your organization to register for an OSGeo Userid, then login into the OSGeo web site, and then go to the form to enter your organization details. There are some directions and discussion at: http://www.osgeo.org/spd_help Feel free to contact me, if you have questions about this service provider directory. We anticipate some fine tuning before we promote it vigorously.

The symposium provides a forum for original research contributions covering all conceptual, design, and implementation aspects of GIS and ranging from applications, user interface considerations, and visualization down to storage management and indexing issues. This year, a novelty is that ACM GIS has separated from its long-time host conference in order to become independent and more visible to the GIS community, further expand the spectrum of research topics covered by the symposium, and grow over the next years. TOPICS OF INTEREST Suggested topics include but are not limited to: Modeling and Querying * Constraint approach for spatial databases * Spatial data quality * Image Databases * Integration and management of raster and vector data * Spatial and spatio-temporal data modeling * Spatial and spatio-temporal data mining and knowledge discovery * Spatial and spatio-temporal predicates * Spatial and spatio-temporal query languages * Spatial and spatio-temporal reasoning * Spatial and spatio-temporal uncertainty, vagueness, and fuzziness * Visual query languages * Spatial and spatio-temporal visualization and analysis * 3D spatial modeling Systems and Implementation * Computational geometry * Geospatial data integration * Geospatial data versioning * Interoperability and standards * Large-scale GIS servers and parallel GIS * Middleware architectures * Multiple representations in spatial databases * Performance metrics and issues * Query processing * Spatial data warehousing and decision support * Spatial query processing and optimization * Spatial, spatio-temporal, and multidimensional access methods * Spatial data mining * Stream processing Applications like * Earth observation * Geosensor networks * Geovisualization * Image databases * Location-based services * Mobile and distributed geographic computing and information services * Novel and challenging applications * Photogrammetry * Real-time applications * Risk prevention * Spatial and spatio-temporal Online Analytical Processing (OLAP) * Traffic telematics * Transportation * Urban and environmental planning * Web applications * Wireless networks PAPER FORMATTING GUIDELINES Authors are invited to submit full, original, unpublished research papers that are not being considered for publication in any other forum. Manuscripts should be submitted in PDF format and formatted using the ACM camera-ready templates available at http://www.acm.org/sigs/pubs/proceed/template.html. Papers cannot exceed 8 pages in length. In addition to the regular full-length papers, the Program Committee may accept some as poster papers which may be requested to be shortened. All submitted papers will be refereed for quality, originality, and relevance by the Program Committee. The acceptance/rejection of the papers will be based on the review results. All questions should be addressed to the Program Committee Chair. One author per paper is required to register and attend the conference to present the paper if accepted for publication. PAPER SUBMISSION GUIDELINES Submissions to the conference will be electronically and online only. Authors are asked to submit an Abstract first, and then to upload the full paper in PDF file format. The online submission system will be available from April 30, 2007.

Maybe other people on this list are interested in this topic as well or even working on it. So, this is to share my ideas and I welcome any feedback. It is not unlikely we (Intevation) will implement something like the laid out concept. So this exercise is not purely theoretical ;-) Naturally, the results will be Free Software. General Introduction -------------------- Driven by practice This concept is driven by practice. The actual needs from the ERP perspective are neither known nor expected to be specified soon. The pricing is vague and subject to change, but not in the near future. Thus, the concept must be flexible. On the one hand it must suffice current needs under current circumstances. One the other hand it must allow to grow/change with more refined specifications about pricing and actual accounting through a ERP system. Request vs. Response It is genereally debatable what facts actually gets logged for accounting. The options are the Request of a user or the Response of the server. This question relates to the structure (i.e. the elements of a request/response), not the actual success (e.g. whether indeed a bimap was delivered or just a error message). It may also relate to quantity (e.g. a WFS request for objects in a certain area vs. the actual number of objects in the response). It appears in genereal more transparent to apply the Request information rather than Response information. Users, various logging etc. do all consider Requests, not Responses. Therefore, this concept focusses Requests. Eventually, consideration of Responses can be added - the concept care for keeping this option open with moderate modifications. Relation to OGC WPOS discussion OGC offers a discussion paper about OWS WPOS ("Web Pricing and Ordering" by Dr. Roland Wagner, http://portal.opengeospatial.org/files/?artifact_id=11500). This concept is regarded as quite complex as it tries to solve various problems at the same time, namely pricing and ordering but also various technical procedures. It is assumed, that a detailed pricing for services has been established already. A method to automatically inform oneself about potential costs if calling a service is described. This proposal is regarded too complex and has assumptions that are currently not met in practice. It does not offer concepts for communication with a ERP system. First point where this concept could touch the concept layed out here is a harmonization of the data model behind the OrderProduct method with the data model described below as configurable. Aims ---- In a secured spatial data infrastructure, identities of the users are known. For various reasons it is of interest for some service providers to know who received which OWS responses when. This would be the base for billing or statistics. By a concrete and immediate need, a simple method to account images sizes of getMap request is required. At the same time it is expected to have more refined needs in the future and the concept should consider this fact already. Aspects and Discussion ---------------------- * Built-into-OWSProxy or Stand-Alone-Module? Integrating the OWS Accounting into a specfic OWS-Proxy (e.g. deegree OWS-Proxy) would have three advantages: - not much overhead in implmentation works - no extra module to handle by the system administration - readily available parser for OWS requests The advantages of a stand-alone module are: - Independent of the actual OWS-Proxy software. - Separat revisioning (this gets very important if many OWS-Proxies should log into the same database, but are installed in different versions) - Independent from specific OWS-Proxy for decisions about programming language and other technologies. E.g. it does not need to be implemented in Java. - process does live on even if OWS-Proxy process dies. Implications for a stand-alone module: - it should run as a background process ('daemon' or 'service') in order to keep open the database connection. Reconnecting e.g. a Oracle database is a expensive operation. * Where to hook in? This must be a place where follwing information are known: - User-ID - Request - WMS-ID Typically this should be the case in a OWS-Proxy such as deegree OWS-Proxy. It seems more desirable to hook into a response processing rather than into a request handling. For deegree OWS-Proxy this could be org/deegree/security/owsrequestvalidator/OWSValidator.java:validateResponse() It must be ensured that the response is a positive one (i.e. no error response). * Which WMS-ID to log? The user may see another WMS name than is internally used (translated by the OWS-Proxy). While for statistics the internal name might also be of interest. The best option would be to log both WMS-IDs. It needs to be clarified where to hook in to the OWS Proxy to get these. * Which requests to log? The module should be flexible to configure the requests that should be logged. It makes sense to leave granularity at the level of the service names (e.g. "getMap", "getLegend") * How to log (data model)? In a first instance logging these information should cover anything needed for billing: - User-ID - Date - Time - external WMS-ID - internal WMS-ID - Request (as is) For actual billing (and statistics) more refined separation of the information inside the request are required. There are basically two options: - create database-side functions to extract certain information from a request, ie. getMapImageSize(req) and apply them when a ERP system collects desired information. - maintain a configuration on which information to log separately for quick and direct access in the database tables. Naturally, the first option depends on the actual database and needs to be implemented anew for any other database. These functions do need the ability to parse OWS requests properly - which means some complexity. In case of a explicit configuration, there are again two options: - have a configuration text file parsed by OWS-Accounting at startup This involves the problem of synchronisation of datamodel as described in text file and as present in database. Next, a generator is needed that creates data model as described in the configuration file in the target DBMS. This may not be integrated into OWS-Accounting but rather imlemented as a stand-alone module (script) because this operation requires higher access grants than OWS-Accounting usually needs. Advantage is, that this likely works with all DBMS the same. - have the configuration inside the database to be retrieved by OWS-Accounting at startup. This solution is more advanced in terms of ensuring data model integrity but at the same time is more complex to implement. Apart from that, different flavours may be needed for differnt DBMS. * Time-Stamps: There are various options which time stamp to log of which some are: - let the database do the time stamp when the INSERT statement is done - send a time stamp from the hooked method. - place a second hook in the request validator to log the time of request not of response. - hook into the web-server for request or for response In normal operation there should be no big difference between the methods around response and around request. There could appear a delay between request and response though. However, the by far easiest method is to apply database time stamps. The requirements of the billing philophy should finally determine the applied method. In case different requirements occur in practice, the method of timestamping should be configurable. * What to do if accounting info can not be written to database? It may occur that the INSERT statement for the accounting fails due to arbitrary reason. It must be defined how to act in such cases. Opportunities are: - Cache the log info and hope for better future and then commit. - Cancel Response - Delay response (and hope for better future _soon_) - Drop the log info (user-luck) Apart from this a alert system could be integrated to inform the system administrator one way or another. Ideally the reaction method should eventually be configurable. * Receipts Even when hooked into Response processing, it is not ensured that the user actually received the response. A receipt mechanism is possible in principle if integrated into InteProxy which sends a additional information (ticket number) of the last response with the next request. InteProxy knows about the response contents because it will parse it anyway. It could send the ticket with the next request to the same OWS as vendor specific parameter. Parsing this the requeuests, whereever hooked in, will find the ticket. This is not a simple implementation, though. It should be carefully decided whether this is needed. However, if implemented it should remain an option to use receipt tickets or not. Iterative development --------------------- The proposed concept is to be implemented in an iterative process where each step leads to a usable application, slowly refining the complexity on the various aspects. Data model ---------- Samples tested with PostgreSQL. The base accounting table: CREATE SEQUENCE owsaccid; CREATE TABLE OWSaccountingBase ( id int, date date, time time, userid character varying(255), wmsidintern character varying(255), wmsidextern character varying(255), request character varying ); Sample insert: i = SELECT NEXTVAL('owsaccid'); INSERT INTO OWSaccountingBase VALUES (i, current_date,localtime,'meier','inteproxy-demo.intevation.org/cgi-bin/frida-wms','localhost/cgi-bin/myfrida','&VERSION=1.1.1&REQUEST=GetMap&FORMAT=image%2Fpng&TRANSPARENT=TRUE&WIDTH=460&HEIGHT=348&EXCEPTIONS=application/vnd.ogc.se_xml&BGCOLOR=0xffffff&BBOX=0.0,0.0,460.0,348.0&LAYERS=gewaesser&STYLES=&SRS=EPSG:4326&SERVICE=WMS'); A sample for an individual table: CREATE TABLE myOWSaccounting ( baseid int, service character varying(10), req character varying(10), bbox character varying(100), width int, height int ); INSERT INTO myOWSaccounting VALUES (i, 'WMS', 'GetMap', '0.0,0.0,460.0,348.0', 460, 348); Configuration ------------- This example corresponds to the above data model examples. Only WMS requests are logged anyway but excluding calls of GetCapabilities. Only for GetMap Requests a special table is filled. -- Dr. Jan-Oliver Wagner Intevation GmbH, Osnabr?ck Amtsgericht Osnabr?ck, HR B 18998 http://www.intevation.de/ Gesch?ftsf?hrer: Frank Koormann, Bernhard Reiter, Dr. Jan-Oliver Wagner From lists at feilner-it.net Tue May 8 16:29:51 2007 From: lists at feilner-it.net (lists@feilner-it.net) Date: Tue, 8 May 2007 16:29:51 +0200 Subject: [Freegis-list] Virtual Reality and Google Message-ID: <200705081629.51850.lists@feilner-it.net> Hello List, As an editor at german linux magazin I am currently writing on an article about virtual reality and google earth.

Message-ID: <200705082024.12530.bernhard@intevation.de> Thuban is back. There was a period of slow development with Thuban, where it just worked. Since the 1.0.0 release of Thuban in 2003 quite a bit of new features got added and released as a development 1.1.0. Our users were never presented a version called stable. Now they are - with Thuban 1.2.0. Beside this long due duty, the new development team has brought Thuban up to be compatible with newer versions of python, wxWidgets, pysqlite and more. There is a new windows installer. This was classic boring maintenance, but now we are in a position to add new features and accelerate Thuban's rate of innovation again. Give Thuban a spin and help us to improve it.

This means those modules need to be robust against a locale where LC_NUMERIC is set in a way that the decimal_point might be a comma or something else. Problems are diagnosed at least with shapelib, proj and gdal. To cope with it we: + Added a new option --setdecimalcommalocale to runtests.py so that all tests can be checked with a comma as decimal_point, if we can find such an LC_NUMERIC. We only try a few in test/localessupport.py. + Fixed behaviour with proj by switching to LC_NUMERIC "C" before initialising the projection and afterward switch back. + Added a workaround to internal shapelib and pyshapelib. (Bernhard Reiter) - Startup improved: We fail right away if the internal encoding could not be determined. In this case, try to set the LANGUAGE variable to one value and use no colon. If we startup you can see the internal encoding in the about dialog now. (Bernhard Reiter) - Support for pysqlite2. (Didrik Pinte) - Added packagin directory, which already has an example how to load all extensions on windows. (Didrik Pinte) - Updated code to support new style wxPython 2.6 imports. So you need at least wyPython 2.6 . (Didrik Pinte) - New Classification "Pattern": Classify text attributes by regexp. (Frank Koormann) - New or Improved Extensions: + Improved svxexport extension 1.0.1 (Bernhard Reiter) * Fixed ARC layer writing: No filling is done. You could actually get polylines with filling in between, when the classification for the lines had a fill color. E.g. this happens when you generate a classification from a ramp. * Fixed label export. + New export_shapefile extension (Jan-Oliver Wagner) Available from the experimental menu. -------------- next part -------------- A non-text attachment was scrubbed...

There is a new windows installer. I just installed Thuban (using Thuban-1.2.0_1.exe from the download area) on mY windows box running XP and it won't start. It mentions it can't find gdal14.dll and wxmsw26uh_vc.dll. I can find gdal14.dll on program files\thuban all right, but I can't find the other on my system. I have a host of wxmsw26*_vc.dll lying around, but not the one DLL Thuban complains for. I've got a few versions installed on my system, so I suspect that's a matter of some environment variable in Thuban reading some system path or registry key. I guess I could change my system PYTHONPATH, but the dlls should be there first (unless I missed something obvious in the installation steps ??).

The reason is that XML parsing capabilities documents, performing additional requests that may result from returned capabilities and doing validations (that can not be done by simply validating the XML) are much to complicated to do it with something like java script. In future an additional reason will be that OGC services will have a SOAP interface. And doing SOAP just using javascript is no fun. best regards ANDREAS -- Dr. Andreas Poth l a t / l o n GmbH Aennchenstrasse 19 53177 Bonn, Germany phone ++49 +228 18496-0 fax ++49 +228 18496-29 http://www.lat-lon.de http://www.deegree.org From bartvde at osgis.nl Thu May 10 10:43:54 2007 From: bartvde at osgis.nl (Bart van den Eijnden (OSGIS)) Date: Thu, 10 May 2007 10:43:54 +0200 Subject: [Freegis-list] Have Geoportal's WMS requests in server or client?

I used to be in favour of the server-side approach, but I've come to like the client-side approach better. Some considerations: 1) on the server you can use Mapscript which gives you advanced projection support for instance (hard but not impossible to do this in javascript) 2) on the server you can integrate all layers into one image which could save bandwidth from the user's browser (third-world countries e.g.) Best regards, Bart -- Bart van den Eijnden OSGIS, Open Source GIS http://www.osgis.nl --------- Oorspronkelijk bericht -------- Van: Stephan Holl Naar: freegis-list at intevation.de Onderwerp: Re: [Freegis-list] Have Geoportal's WMS requests in server or client?

Yves, Ari, thanks for your reports. Indeed the Thuban-1.2.0_1.exe needs a few prerequisites installed and one system path change to run. On https://intevation.de/mailman/listinfo/thuban-devel you will find the discussion about it and links to new windows installers for testing which have several issues fixed.

Thank you in advance! With GRASS 6.3 (not yet officially released but snapshots are available) you can elaborate 3D data and export to KML. For example, you can take a 3D drawing (DXF), import with v.in.dxf, geocode with v.transform and export to KML with v.out.ogr as 3D object. Note that the KML support in OGR is still somewhat limited but I managed to export 3D buildings. Additionally, if needed: - reproject to LatLong with v.proj - extrude 2D building footprints to 3D blocks with v.extrude - drape 2D vectors over DEM with v.drape Not really helpful maybe, but giving an idea, Markus PS: Works on MS-Windows/MacOSX, too :) ------------------ ITC -> dall'1 marzo 2007 Fondazione Bruno Kessler ITC -> since 1 March 2007 Fondazione Bruno Kessler ------------------ From daij at leda.nvc.cs.vt.edu Thu May 10 18:11:39 2007 From: daij at leda.nvc.cs.vt.edu (daij@leda.nvc.cs.vt.edu) Date: Thu, 10 May 2007 12:11:39 -0400 Subject: [Freegis-list] Call For Papers - SSTDM 2007 Message-ID: <20070510161139.GA16809@leda.nvc.cs.vt.edu> ------------------------------------------ Workshop on Spatial and Spatio-Temporal Data Mining INTERNATIONAL CONFERENCE on DATA MINING 2007 (ICDM??07) http://spatial.nvc.cs.vt.edu/sstdm07 Call for Papers ------------------------------------------ October 28, 2007 Omaha, NE, USA Widespread use of sensor networks and location aware devices has resulted in large amounts of spatial and spatio-temporal datasets in a variety of domains. The number and size of these datasets continues to increase rapidly, making their manual processing impossible. It is therefore, imperative that efficient and effective techniques are developed to extract useful information from these datasets. Traditional data mining techniques are ineffective in the spatial domain since they don??t incorporate the special features of the spatial domain, e.g. spatial autocorrelation. The goal of the workshop is to bring together researchers, developers and practitioners in the field of spatial and spatio-temporal data mining together in order to identify current research foci, vital areas of need, and critical points of synergy. Selected papers will appear in the GeoInformatica journal as a special issue. TOPICS OF INTEREST Topics of interest include but are not limited to: o Theoretical foundations of spatial and spatio-temporal data mining o Novel techniques for spatial and spatio-temporal data mining o Role of uncertainty in spatial and spatio-temporal data mining o Visualization techniques for spatial and spatio-temporal data mining results o Languages and primitives for data mining o Web mining techniques for spatial and spatio-temporal data o Spatial and spatio-temporal data mining at multiple resolutions o Scalable techniques for spatial data mining o Applications and case studies in spatial and spatio-temporal data mining o Data mining techniques for dynamic spatial and spatio-temporal data o Role of spatial analysis in spatial and spatio-temporal data mining o Data structures and indexing methods for spatio-temporal data mining o Data mining from unstructured spatial and spatio-temporal data PAPER SUBMISSION This is an open call-for-papers.

Standard GetMap requests are started directly from the client browser using JavaScript. This is faster as it does not involve an intermediary server to formulate the request. The map starts to build up once the first server has answered. If one of the services does not answer it does not block the others (as in a cascading architecture or with an intermediary proxy server). To do this the client needs to have a copy[1] of the Capabilities document to be able to formulate initial GetMap and FeatureInfo requests. Mapbender maintains a repository of Capabilities and ISO 19119 metadata describing them. CS-W 2.0 has been extended to allow loading single layers from a query result instead of having to always take the whole services. The copy of the Capabilites document that served to set this information can be updated manually or by a monitoring service [2]. The OGC WMS spec does not provide for a notification or push method yet (here rss could be used as a workaround). It is possible to preconfigure the initial request, select layers, image and query result format, initial start extent (if it is the first service), etc. In some cases it will be preferred or even required to request all images to one central point and merge / weld them. This is helpful when creating PDF print out files. PDFs regularly fail when different raster image formats with transparencies are overlayed, the result if often a solid black. FeatureInfo requests from different services will usually pop up each in a separate window, with different layout, etc.. To enhancement this one server can collect the results and merge them into one single window or iframe on a web page [3]. Another issue is security. If each request needs to be logged by a component that has authentication information (for example data with privacy relevant data) then the requests should be cascaded through a security proxy[4]. There will be many more application examples and for each an individual combination of server or client side requests can make sense. It will be interesting to implement everything again with WSDL. But this is still in the queue and nobody knows when it will be available as a spec and even less so whether people will actually want to use it. Best regards, Arnulf.

The one site where I could actually figure out what was going on was based on MapGuide 6.3. This is a proprietary technology, which is reliant on an ActiveX control (or old netscape plugin). MapGuide 6.x was actually a pretty decent tool in its day (we use it at the City of Nanaimo) but I sure look forward to moving away from ActiveX and embracing a cross-browser open source tool.

Well, when I started the project, I simply compiled the packages for myself, and while I was doing it, I simply setup the repository, so others can use the packages too. I never did any big improvements of the original debian files. I just change the debian/control and debian/changelog files, so it matches actual versions of all required libraries. Since your are not first, how is asking me this question, I start to think about it. I'll contact the ubuntu/debian-gis people and ask them, if there is something I could do, to get fresh packages for ubuntu (and debian) ready earlier, then they are provided now. > > Those of you who are using Thunban on Ubuntu: > Do use the standard repositories because the new packages will lead to > the uninstallation of Thuban: > > If I try to reinstall Thuban after installing the new packages I get the > following error message by Synaptic: > > H?ngt ab: ?libgdal1-1.3.2?, aber es wird nicht installiert. > Empfiehlt: libgdal1-1.3.1 (>=1.3.1-1) but it is not installable > Empfiehlt: ?python-gdal?, aber es wird nicht installiert. > > => Maybe you (or Intevation) could provide thuban as well...

Message-ID: <662159.29739.qm@web63407.mail.re1.yahoo.com> Hello, I have a question concerning the architecture of WMS/WFS and PostGIS: Is PostGIS just for WFS or could it be used also to store the card material for a WMS? - How typically a WMS stores its card material? Also in sort of a database? - Is it standardized? Or is the card material just stored in a directory/file structure without database functionality? Furthermore, I found the following PDF: http://lists.refractions.net/pipermail/postgis-users/attachments/20020424/20dcffd7/OGC-OSS.pdf On page 2 the WFS on the bottom acesses Rasters and Images. But I thought, WFS is just for vector data (features), stored in e.g. ESRI shapes or PostGIS, like the other two datasources. But is it really true like in this diagram that a WFS also can access raster images? - I thought this is normally done by WMS/WCS? Please could anyone help to clear my confusion? Best regards, Peter.

The number and size of these datasets continues to increase rapidly, making their manual processing impossible. It is therefore, imperative that efficient and effective techniques are developed to extract useful information from these datasets. Traditional data mining techniques are ineffective in the spatial domain since they don??t incorporate the special features of the spatial domain, e.g. spatial autocorrelation. The goal of the workshop is to bring together researchers, developers and practitioners in the field of spatial and spatio-temporal data mining together in order to identify current research foci, vital areas of need, and critical points of synergy. Selected papers will appear in the GeoInformatica journal as a special issue. TOPICS OF INTEREST Topics of interest include but are not limited to: o Theoretical foundations of spatial and spatio-temporal data mining o Novel techniques for spatial and spatio-temporal data mining o Role of uncertainty in spatial and spatio-temporal data mining o Visualization techniques for spatial and spatio-temporal data mining results o Languages and primitives for data mining o Web mining techniques for spatial and spatio-temporal data o Spatial and spatio-temporal data mining at multiple resolutions o Scalable techniques for spatial data mining o Applications and case studies in spatial and spatio-temporal data mining o Data mining techniques for dynamic spatial and spatio-temporal data o Role of spatial analysis in spatial and spatio-temporal data mining o Data structures and indexing methods for spatio-temporal data mining o Data mining from unstructured spatial and spatio-temporal data PAPER SUBMISSION This is an open call-for-papers. Only original, high-quality papers, in-line with the ICDM??07 standard guidelines, will be considered for this workshop. The manuscript should not exceed 6 single-spaced, double-column pages, including figures and tables. The font size should be at least 10 point. The submission paper should be in PDF file format. Prospective authors should submit electronically their contributions at the following website: http://wi-lab.com/cyberchair/icdm07/scripts/ws_submit.php This is an open call-for-papers.

Peter, we use PostgreSQL/PostGIS as datastore for the software GeoServer (Java) as WFS to access geometries (vectors). This is good to query for street address, name gazetteer, zoning data, floor map and if configured as transactional service it is also good for updating (editing) geometries via web. To visualize (render) maps we use the software MapServer (C++) that accesses the very same PostgreSQL/PostGIS database. That way we can use the best tools for the corresponding job that are on the market to produce optimized results. MapServer is fast, stable and has a powerful cartography but lacks WFS transactionality. GeoServer knows how to use transactions on a WFS and can write back but is less powerful on cartography. Late binding of both is done with the application framework Mapbender (PHP and SQL which incidentally can also be stored in a PG/PostGIS box, opening up even more possibilities). > Furthermore, I found the following PDF: > > http://lists.refractions.net/pipermail/postgis-users/attachments/20020424/20dcffd7/OGC-OSS.pdf > > On page 2 the WFS on the bottom acesses Rasters and Images.

My personal take is to leave rasters outside databases, we have several high performing libraries and compressions algorithms so that there is no need to stuff all into a database. Raster output in most cases will either come from a WMS (nice but dumb) or WCS (there aint many but those few are real smart).
