Message-ID: <755714.91168.qm@web62007.mail.re1.yahoo.com> Hello, I have some general questions about what ones can do with free GIS. I am not sure whether there is a viewer available to realize the following funtionality in conjunction with any free GIS and if yes, how difficult that would be: I want to visualize realtime data (moving objects) over a map. Ideally it would be possible to have a perspective view of the map like Google Earth or World Wind. Furthermore, it would be nice to be able to select an object on the map (e.g. a building) and to show it from the side in 3D (using OpenGL or sth. like that) in a separate window. Therefore it should be possible to store such 3D information (e.g. of the buildings) in a way to allow to extract the 3D model (based on the coordinates on the map when it is selected) and to feed it into the 3D viewer. So here are my questions in more detail: Is there a free GIS with which it is possible (and if yes with what efford) to 1. get the current camera view via asynchronous events every time the view changes? Or do I have to solve that with a polling mechanism? - Do you have some sample code doing this, preferably in python? 2. display moving overlays 3. display movements and directions of 3D Objects in realtime, e.g. 10 fps? 4. doing all this using a scripting language like python? 5. doing this using standard protocols like TCP/IP or HTTP? 6. platform independent (OSes Linux, MacOS, Windows)? 7. extend the funtionality via plugins? 8. licensing conditions, GPL or sth. like that and having to disclose my code? 9. support for special input hardware like spacemouse, joystick etc? 10. Is there an API? 11. What is the resolution for regions like Europe (meters/pixel)? - What is the best available and what does it cost? You would greatly help me in answering a part of if not all questions (which would be awesome!) since I try to figure out whether there is a free GIS suitable for a medium sized research project I am working on. So if anyone could answer, many thanks in advance and best greetings. --------------------------------- Never miss an email again! Yahoo! Toolbar alerts you the instant new Mail arrives.

Some options to try: http://www.open3dgis.org http://vtk.org http://www.opendx.org http://vis5d.sourceforge.net http://grass.itc.it/ I've used OpenDX, it may be able to do what you want, VTK is more of a toolkit approach to build your application, so may be more suitable. NVIZ, the 3D module in GRASS GIS may also be useful. I suggest you also look at some Open Source 3D gaming alternatives. For example, the rendering code in FlightGear may be able to be used for your purposes.

INSPIRE mandates that data providers follow 'Implementing Rules'; the first of these, on metadata for geodata, is in public consulation. http://wiki.osgeo.org/index.php/Reading_the_INSPIRE_Metadata_Draft OSGeo's Geodata Committee is putting together a reading guide and formal response to the Metadata Implementing Rules. The rest of this email explains the background to the process. Everyone who Cares A Lot About Metadata is encouraged to participate in the response, which will be written openly on the wiki. INSPIRE will oblige public authorities collecting and holding geodata to comply with a set of Implementing Rules which are still being defined. The implementing rules for metadata were published at the beginning of last month. The draft for public consulation is publically available, but comments and improvements can only be submitted through an SDIC or Spatial Data Interest Community. Thanks to Markus Neteler, the open source geospatial community has an FOSS SDIC available to it. Recently having had the chance to speak with Metadata Drafting Team participants and hear the process outlined by Alessandro Annoni of the Joint Research Council, I am more convinced now that this isn't simply "illusion of participation", but that the JRC really is in search of best practise and sanity checking of what has been produced. All the other Implementing Rules drafts will be built up from, and refer to back, this one. If you are in any way involved in the collection or publication of geodata through any publically funded institution in Europe then what results from these IRs will affect you, and this is our first and last chance to affect the process. If you want to help out, this is what to do: - Read the draft! If you don't have time to read the whole draft but want to know what is going to affect you, quick pointers are at http://wiki.osgeo.org/index.php/Reading_the_INSPIRE_Metadata_Draft#Reading_the_draft - Sign your name up to the wiki page if you want to be included in the loop (this is the last cross-list spam about this you will see from me, and followups/discussion should go on the wiki, not via email) http://wiki.osgeo.org/index.php/Response_to_INSPIRE_Metadata_Draft - By the 20th the useful parts of [Reading] will have moved over to a more formal version at [Response] and there will be a week during which one can edit that page. - Then we will de facto lock it down for final edits - On the 27th or so i hope to have a telecon and after that move the response into the form required by the feedback process for SDICs. Even 5 minutes spent structuring, editing or proofreading would be of great help; Many eyes make better metadata... cheers, jo From pramsey at refractions.net Mon Mar 5 19:59:10 2007 From: pramsey at refractions.net (Paul Ramsey) Date: Mon, 05 Mar 2007 10:59:10 -0800 Subject: [Freegis-list] FOSS4G 2007 Call for Presentations Message-ID: <45EC687E.8010209@refractions.net> We are pleased to announce a Call for Presentations for the 2007 FOSS4G (Free and Open Source Software for Geospatial)conference, being held September 24-27 in beautiful Victoria, British Columbia, Canada. http://www.foss4g2007.org FOSS4G is the premier conference for the open source geospatial community, providing a full-immersion experience in established and leading edge geospatial technologies for developers, users, and people new to open source geospatial. FOSS4G presentations are 25 minute talks, with 5 minute question and answer sessions at the end. Presentations cover the use or development of open source geospatial software. Anyone can can submit a presentation proposal and take part in the conference as a speaker. Some topics of interest for this year are: * Case Studies: Relate the experiences of you and your organization using open source geospatial. Where do things work well? Poorly? What problems did you solve, and at what cost? What do you recommend for others? Why? * Benchmarks: Comparisons between pieces of geospatial software. How do features compare? Speed? Ease of use? What do you recommend for others? * Visualization: Tell about your tips and tricks for effective visualization. How do you present information in a compelling way? 3D? Cartographic tricks? Labelling and naming ideas? Graphs and hybrid map/data combinations? * Development: What are the new developments in your open source geospatial software product? How does it work, how do people use it, what are the technical issues you are running into? * Hacks and Mashing: Have you put together something novel or cool this year? What did you stick together, how did it work, show us your gizmo! * Collaboration: What techniques are you using to improve collaboration between organizations and between individuals. Public geodata, collaborative data collection, data sharing, open standards, de facto standards, and more! If you have an open source geospatial story to tell, we want to hear it! For more information, see the FOSS4G site: http://www.foss4g2007.org/presentations/ The deadline for presentation submissions is June 29, 2007. Submit early, submit often!

One question: the NVIZ component, could I use that isolated from the rest of GRASS GIS, i.e. without all the other components to keep my system small and fast? Yet another question: Do you know whether there is a fast, thin client for accessing Web Map Services (WMS) which does caching when getting raster data (so that e.g. when I shift the current field of view, the client not always has to reload new data from the server)? Whether 3D or only 2D plays no role, optional 3D would be nice, however. And one last question: When I get realtime data from a server, e.g. GPS data of some object, is it possible to overlay that data over a map with a WMS without storing the data in a database (which, I think would slow down the realtime process because of the hard disk access)? Speed is an issue in my scenario. You would greatly help me since I am a newbie in this area, so be thanked in advance for any help. Best regards, Peter. --------------------------------- Expecting?

OpenLayers.org - not 3D but caching - Javascript. http://www.ossim.org/OSSIM/ossimPlanet.html - 3D, caching, but not a web client. > And one last question: When I get realtime data from a server, e.g. > GPS data of > some object, is it possible to overlay that data over a map with a WMS > without storing the data in a database (which, I think would slow > down the > realtime process because of the hard disk access)?

I wouldn't think so, but you might check the GRASS list for advice. NVIZ was originally a separate packages, AFAIK, but whether it is still available that way I don't know. I believe it is likely that the GRASS data management tools etc will still be useful. > Yet another question: Do you know whether there is a fast, thin client for > accessing Web Map Services (WMS) which does caching when getting raster > data (so that e.g. when I shift the current field of view, the client not > always has to reload new data from the server)? Whether 3D or only 2D plays > no role, optional 3D would be nice, however. I know OpenLayers does this (via tiles & using transparent images for each layer), I'm not sure about other WMS/mapserver toolkits like Ka-Map!, MapLab, FIST, etc. > And one last question: When I get realtime data from a server, e.g. GPS data > of > some object, is it possible to overlay that data over a map with a WMS > without storing the data in a database (which, I think would slow down the > realtime process because of the hard disk access)? Speed is an issue in my > scenario. Yes. UMN mapserver scripts can do this pretty easily (I haven't done so, but know others that have). Just choose your language :-) I'd guess other WMS server packages have similar functionality. Of course, unless the users screen is automatically updating, it won't pick up these changes anyway. Such updates will tend to make your maps somewhat behind "real time", probably barely "near real time", but I don't see any way around this when the general internet, with its latencies, etc, is used. > You would greatly help me since I am a newbie in this area, so be thanked in > advance for any help.

One question: the NVIZ component, could I use that isolated from the rest of GRASS GIS, i.e. without all the other components to keep my system small and fast? Yet another question: Do you know whether there is a fast, thin client for accessing Web Map Services (WMS) which does caching when getting raster data (so that e.g. when I shift the current field of view, the client not always has to reload new data from the server)? Whether 3D or only 2D plays no role, optional 3D would be nice, however. And one last question: When I get realtime data from a server, e.g. GPS data of some object, is it possible to overlay that data over a map with a WMS without storing the data in a database (which, I think would slow down the realtime process because of the hard disk access)? Speed is an issue in my scenario. You would greatly help me since I am a newbie in this area, so be thanked in advance for any help.

BSD-4 ("old") is not. 3,4 stand for the number of clauses. The advertisement clause in BSD-4 is causing trouble. If your code is under BSD-3, you are on the save side with your text as above.

With Google's excellent free mapping program Google Earth, you can use this site to visualize a wide variety of data best displayed on a map. Currently, only the US Census 2000's Summary File 1 (displaying population characteristics such as race and age) is available for mapping. I hope to have additional data sets, such as income (Summary File 2) and voting statistics, available soon. # Is gCensus Free Software? * Yes! I haven't gotten around to doing any proper packaging on it (it's a pretty involved application, written in a variety of languages including Perl, PHP, PL/PgSQL, and JavaScript), but my intention is to release it under an OSDL-compliant Free Software license when I can get the time.

GRASS is the opposite of monolithic :-) It's absolutely modular, you just need a few lines of shell script (or batch file) to launch one of many commands: http://grass.gdf-hannover.de/wiki/GRASS_and_Shell http://grass.gdf-hannover.de/wiki/GRASS_and_PHP http://grass.gdf-hannover.de/wiki/GRASS_and_Python Non-distributed GIS: You can run GRASS con clusters if you mean this (I didn't read the entire thread, sorry). mobile GRASS: In 2002, we developed "babyGRASS", a 2MB version by just extracting the modules (commands) we needed for our iPAQ devices: http://grass.itc.it/platforms/grasshandheld.html (my hand in front of the scenic environment around Trento) There was also a GRASS Server 2004 Radim Blazek, Luca Nardelli: The GRASS Server http://gisws.media.osaka-cu.ac.jp/grass04/viewabstract.php?id=30 It came with voice interface - there should be a film somewhere demonstrating how it worked. A modern variant is PyWPS (Python Web Processing Service): http://pywps.wald.intevation.org/ it has been written with native support for GRASS, using this some client-server model could be invented.

Your (and of course of the other guys) tips are gold. That GRASS and WMS get together is really nice. Maybe exactly what I need. Some questions (the last I hope) do I still have: Is it possible with WMS (maybe using Styled Layer Descriptors, SLD) to write back vector data into the layers stored on the server (WFS for vector data I guess)? Or is access read-only? Is it possible that the views interact with each other, e.g. on the tablet shifting the map displayed onto the table (in the other view) or switching to another map/layer? Are there raster layers in WMS/WFS I can switch on and off? Can I define points of interest (POI) so if the user clicks on a point in a map I can reference to a database to display information about the object (POI) he clicked onto? Can I control the contents of the view (shift, zoom etc.) from the outside e.g. by a script/program, or are there only the manipulators in the view?s interface for zooming, shifting the map cutout displayed in the view (e.g. the GRASS viewer or others)? So I hope you would also be so kind to answer those questions, too, thank you again for your great help you already provided.

Some details (especially concerning WMS/WFS/WCS) are still not that clear to me. At best the following could be realized by a GRASS GIS configuration which conforms to a WMS/WFS/WCS architecture: Some questions do I have to your answers: 1. I thought the WMS server puts together the data it gets from the WFS (vector/feature data) and from the WCS (raster data) into a single raster image? 2. Daniel, as far as I have figured out, WFS basic is without write access, and WFS-T (transactional) is with write access. Do UMN MapServer or GRASS GIS (Markus) already support this? It would be important to be able not only to change styles (like with the SLDs) but to do annotations (I tried FIST on their site, its nice, but annotations failed when I tried ? the map wasn?t displayed any more) or even change the vector data already stored in the vector layer database (WFS for example). 3. With GRASS GIS, is it possible that when the user interacts with one view (in the tablet PC ), he also manipulates (shift, zoom, change layer) the other view (in the table)? If not yet, would GRASS GIS be customizable to do so? 4. Does GRASS GIS (even over a WMS/WFS/WCS infrastructure) support POIs so if the user clicks on a point in a map I can reference to a database to display information about the object (POI) he clicked onto? 5. In the same constellation (GRASS GIS with WMS/WFS/WCS), is display of realtime vector data coming in from sensors like GPS signals overlayed over the map possible? ? The architecture would be an additional data source (to WFS and WCS) with the GPS signals and the WMS puts them together to one raster image and sends them to the multiple views? ? By the way, the views are different, not identical. So it would be nice to realize such an architecture, if possible solely with GRASS GIS or, if reasonable, together with UMN MapServer. I can not thank you often enough for your help so far, it would be awesome if you could also answer the questions above. ? Many thanks and till soon, I will let you know my decision and experiences I will get with it. Best regards, Peter.

Sort of, yes, that is a typical basic WMS operation. However some more intelligent WMS client applications (eg, OpenLayers) enhance this, by doing things like downloading layers as separate transparent PNG's & overlaying them locally in the client. Thus a "redraw" with layers turned off is pretty much instantaneous, as the client turns off that PNG. It also downloads the images in tiles covering an area greater than the the actual region shown, & caches them locally, so any panning/scrolling is often managed with no WMS calls, just local images. This does create initial overhead, as each layer/tile is a separate WMS transaction, but provides a much better viewing experience IMHO :-) Note, however, that a WMS does not generally get it's data from a WFS, but from the same underlying vector data repositories that a WFS uses. They usually independently access the same data. As I understand it, the overlay of WFS vector features om WMS maps is done at the client end, to allow client interaction with the features. > 2.

I haven't used FIST for quite a while. Looked at that, MapLab & Ka-map, but have pretty much found OpenLayers suits our needs at the client end. (these are all different clients/client building apps that do quite different things). Mapserver is not a WFS server. I understand the combination of Geoserver as a WFS-T engine and mapserver as a WMS engine is popular. See http://docs.codehaus.org/display/GEOSDOC/WFS geoserver also supports WMS, so you do not actually require mapserver, but there seems to be an overall feeling in the user community that mapserver overall is a better WMS provider. But I guess opinions will vary :-) (I'll leave the GRASS questions to those who know it better :) > 5.

By the way, the views are different, not identical. Yes. via several means. We use GPS data fed straight into a PostGIS database which is re-rendered via a WMS server every few seconds. Not elegant but goos enough for our at-sea needs. Things like Geo-RSS feeds of the data may be possible. A mapserver mapscript application could certainly access an NMEA GPS stream on a serial or UDP port & enable it as a layer, or via a mapserver WMS layer with an SQL selecting just the last n values in a Postgis table where the data is automagically logged to. OpenLayers could be tweaked to refresh just this layer automagically. Ther are many approaches by which this can be (& has been) done. Fleet/vehicle tracking apps for exanple.

If not yet, would GRASS GIS be customizable to do so? A possibility which would necessitate quite some programming manpower is to rewrite GRASS display and editing modules (which are the ones you are trying to distribute over several interlocked displays) using a toolkit such as Ubit over X11 (http://www.infres.enst.fr/~elc/ubit/). You use an X11 server on each of your tablets and the main table display, and the central application deals with distributing display and also (and that is the tricky part, AFAICT) distributes input events from each device. I'd say you would need to rewrite at least xganim, nviz and build some client-server driver for the rest of display capabilities. A very nice project, BTW. Keep in mind that GRASS is not your typical interactive application, but a collection of modules that interact with a central datastore. Display and edit are only some of its capabilities.

Just wanted to say that if you are interested in OGC Web Services and 3D it might be a good idea to have a look at deegree (www.deegree.org). A 3D database and visualisation service (WTS) as well as WMS/WFS/WCS are available there. In April/May the 2.1 demos of these components will be released - these will be very easy to install (WAR-archives, all inclusive). If you are interested before, you would have to access the deegree CVS directly. regards, Markus Peter Fischer schrieb: > Thank you all for your answers, Brent, Markus, Daniel and Paul, > > It looks like GRASS GIS (because of its 3D capabilities) and/or UMN > MapServer > are good choices for me.

I'm a little confused because I thought WMS/WFS/WCS already support 3D data? But that seems not to be the case as far as I have read in the Web (Wikipedia, google). Therefore are the Web Terrain Service (WTS, static data only without time domain) and the Web 3D Service (W3DS, server delivers 3D scene graph and the client can combine the data from various sources). The question is: are there already open source implementations for W3DS? I would need the time domain for my realtime GPS data source. The clients (viewers) would then overlay them over the terrain data. Yes, deegree also seems to be an option when the 3D functions are ready. What viewers are available for that (client side)? Could I combine it with the GRASS viewer? Is W3DS support planned for deegree? (The standard seems to be not yet adopted by the OGC?) When not over a full blown 3D terrain, is it possible to overlay the realtime data over a 2D map in your current implementations (this maybe would also be sufficient for my purposes)? Its interesting to discuss with you, I think I am near to the core of my recherche task. Thank you so far, I hope you like to answer the questions above?

I've done interactive 3D plots, with land & sea terrain models (each in a different vertical scale & with a different color map), a translucent sea surface plane, elevation contours showing daily mid-water fish catches using 3D symbols for catch locations. The user could interact with this to choose the column (dimension) to size & colour the symbols (glyphs), total catch, target species catch, size of vessel, mean length of target species for size & time of day, vessel type, % target species, etc. for colour. While I built this as an animation with each day as a frame, it was also interactive so the user could rotate, zoom, stop, start, rewind, etc. DX is implemented as a data flow model, rather than a traditional programming paradigm, with data moving through user selected & configured modules to generate the required output. OpenDX is not strictly a GIS, but a multi-dimensional visualisation tool. It was used for 3D terrain visualisations long before traditional GIS tools started coping with 3D (& most GIS tools still don't, they manage surfaces, not volumes). See: http://opendx.sdsc.edu/animations/gis/raelakes.mpg http://opendx.sdsc.edu/animations/environmental/calabasas.mpg for examples. In DX there are controls to make such things interactive & very responsive. Vizualisations, Inc is a company which provides commercial support & training for DX if required. IBM's training notes are available, see http://www.research.ibm.com/dx/proceedings/cart/tutorint.htm for an example. I'm not saying that other Open Source GIS tools are not able to do this, just that there are alternatives which are not traditionally regarded as GIS, which may be worth checking out.

I'd describe it as a mature package that does what it needs with few problems. Unlike most OS packages, this used to be a very expensive commercial application, IBM's Data Explorer. Back in '99 IBM released the code to the OS community, along with their adoption of Linux. So it is not an application started & maintained by a team of devoted OS enthusiasts, and I don't think it is not entirely fair to condemn it because of this. I agree that additional functionality is not being added, so development is static from that perspective, but the application already does it's job very reliably & effectively, so I'm not overly concerned about that. In the same genre of 3D visualisation tools as DX, there is also KitWare's VTK & other OS visualisation packages, which are more like toolkit to build your own apps, than an off the shelf application. I guess my overall point is that there are thousands of Open Source visualisation, 3D modelling & 3D rendering packages, several of which are very capable terrain modellers & Earth visualisation tools. For whatever reason, these are often ignored by traditional GIS people. NVIZ is one of the few such packages to be actively integrated into the OS GIS community. Just look at the 3D rendering, earth sciences, 3D modelling & visualisation categories on Sourceforge. While the vast majority of these packages are not appropriate in this case, some time spent searching resources like this could realise some directly useful packages. The ones I mentioned are not even Sourceforge packages.

I can only reply to this in regard to deegree.

So did I understand that correctly, deegree supports hosting of static 3D data in a database and its display via WTS? 2. I would like to efficiently display realtime data (GPS positions) e.g. as moving (vector-) dots over a map, ideally the 3D map, but maybe display over a 2D map would be sufficient. The option for later 3D display would be good, however. The idea is to stream the incoming GPS data directly to the client for fast display, but parallelly branching a copy of it to a server sided database for latter review (to be able to rewind, pause, play,...) by the user (via the client). Could I realize such an application with deegree as the server and maybe NVIZ as a viewer (client)? That was what I had in mind when asking for the combination with GRASS GIS (which uses NVIZ). So if there would be a way (even with 2D maps only) with deegree and the realtime data I would be happy. So I am looking forward to your answer, thank you again for the help so far.

I cannot give a good reply to this, although I can say: I guess you can d so! ;-) You can surely display maps with deegree (WMS and iGeoPortal).

Walter, Note that the problem with mapguide isn't *building* on 64 bit systems, it is running on 64bit systems. If this is your first foray into mapguide I don't think you will want to be running it in such broken configuration. This supplied 3rd party libraries are the versions that mapguide is known to work with, and in at least some cases they have been locally modified with required fixes. So build against other versions with caution. You should visit the http://mapguide.osgeo.org web site, and read up about how to contribute as a developer. Briefly you can file bug reports and attach patches via Trac at: http://trac.osgeo.org/mapguide Best regards, -- ---------------------------------------+-------------------------------------- I set the clouds in motion - turn up | Frank Warmerdam, warmerdam at pobox.com light and sound - activate the windows | http://pobox.com/~warmerdam and watch the world go round - Rush | President OSGeo, http://osgeo.org From pcreso at pcreso.com Mon Mar 26 22:24:02 2007 From: pcreso at pcreso.com (Brent Wood) Date: Mon, 26 Mar 2007 13:24:02 -0700 (PDT) Subject: [Freegis-list] Free spatial data In-Reply-To: <631521763@web.de> Message-ID: <57004.43271.qm@web33201.mail.mud.yahoo.com> --- Katharina Schr??der wrote: > Hello everyone, > > I need your help!

I thought this might be of interest to other open source GIS projects, so I am sending a brief message here. I'd be willing to work with developers from other projects on a format that could be used by other applications. I've put a rough draft of the format here: http://thejumppilotproject.pbwiki.com/OpenJUMP-Binary-Feature-Format Let me know if your interested, or if you have any suggestions. I hope to finalize the format in the next week or two. In the next month or two I hope to have a working parser for the binary format in Java that will be released under the GPL through the SurveyOS SourceForge Project.

Message-ID: <460E1052.3010603@tkk.fi> Hello, Does anybody know of a geospatial graphics library that is built on Cairo? Would anybody be interested in starting a project to build one? I know we have Mapnik, which seems to be very good etc (I haven't tried it), and maybe others but my point here is Cairo. Having a Cairo based library, would open up possibilities for building GTK (Since 2.8, GTK+ does most of its drawing using Cairo.) and Gnome geospatial applications. Cairo (http://cairographics.org/) from it web page: Cairo is a 2D graphics library with support for multiple output devices. Currently supported output targets include the X Window System, Win32, image buffers, and PostScript, PDF, and SVG file output. Experimental backends include OpenGL (through glitz), Quartz, and XCB. I've been wanting to have a library like this for a while now. Basically the library would use the services of Cairo and GDAL (and OGR). It would be written in C. I'm not very sure what would be the best way to feed the style etc. information into the library. OGR has at least some support for styles, but I'm thinking that the usage of this library would be more in "visual geoanalytics" and thus the styling information needs to be very flexible and extendable.
