I'm not using these pacakges myself. But I thought others might like to try instead of building newer versions on their own. Maciek -------------------- W polskim Internecie s? setki milion?w stron.

The range of values that you have in your case is much smaller than 1/64 (0.015625), that's why you get that kind of result. I didn't try myself, but I think you should be able to solve this by editing gdchart2/gdchart.c, look for the ypoints[] array around line 920 and add more smaller range values that suit your needs.

A great page which allowed me to produce some of the maps I am after. But unfortunately not the one I really want. Insted of just plotting the points in 2D, I would like to plot the density of the points in the 3rd dimension. In the 2D map the points are just drawn above each other and it is not possible to see how many there are. What I am after is some thing that partitions the grid into cells and represents the number of point which fall into every cell in the 3rd dimension. Hope this makes sense.

Sounds like Grass should be able to do the job: - import GPS points into points vector layer: v.in.garmin (if using Garmin) / other v.in.* module (depending on how your GPS points are stored) - convert into raster grid layer storing the number of points in given vicinity as each cell value: v.neighbors - visualize the raster: nviz More: http://grass.itc.it/gdp/manuals.php.

Ben, The binary long data type is just a fragment of the same geometry format used in the shapefile format. This fall support for Geodatabase (via ODBC) was added in OGR with no need for ESRI software installed on the system. Just using the normal mdb odbc drivers available on windows.

The meeting was a great success, and the Open Source Geospatial Foundation (OSGeo) was born. http://www.osgeo.org/ The physical attendies are the first members of the foundation. At the founding meeting it was resolved to add a second tranche of members as quickly as practical after the meeting, bringing our membership up to 45, in order to broaden representation and give other interested a chance to be most directly involved. This email is the formal call for nominations. Nominations should be emailed to Chicago at osgeo.org and should include a paragraph describing the qualifications of each nominated candidate. All nominations should be in by 9:00am (Pacific time - GMT+8) on Thursday February 16th. After that they will be collected and the existing membership will vote to select 24 new members from the nominations. Please verify with any nominee that they are willing to stand for membership before nominating them. Nominations already sent to chicago at osgeo.org will also be incorporated. Note that you do not need to be an existing member to nominate someone, and self-nomination is fine. Previously suggested (but unofficial) membership selection criteria include: o The person should have made a contribution to open source geospatial software already. o The person should be willing to put in time and effort on the foundation, perhaps joining committee(s), or volunteering in some other way that gets the foundation going. o Members should believe in the general goals of the foundation.

This release brings a number of improvements to make GeoServer the easiest way to get a powerful open source standards-based web mapping solution up and running quickly. GeoServer has traditionally focused on WFS, which allows access to the raw vector data, serving as the WFS reference implementation. 1.3 brings fully compliant WMS and SLD, which handle the rendering and styling of maps, available as JPEG, PNG, GIF, SVG and KML. Official OGC certifications are in the works for both WMS and WFS, as all compliance tests have been passed. Continuing the focus on ease of use, GeoServer now includes an integrated MapBuilder (http://mapbuilder.sourceforge.net) AJAX-based client to instantly preview any GeoServer layer. Configuration is still a cinch with a web based interface, and all layers are 'standard by default', no need to modify each layer just to have data served correctly. Sharing GeoServer configurations has been made easier with configurable data directories. The documentation has also been greatly improved, transitioning to a wiki-based solution, available at http://docs.codehaus.org/display/GEOSDOC/Documentation Several new data formats are also reaching maturity, adding DB2, Cascading WFS, MySQL, VPF and MapInfo to the already established PostGIS, Oracle, ArcSDE and Shapefile. The WFS will also now produce Shapefiles directly, instead of only GML. Internationalization has been greatly improved, including a new Japanese translation of the web admin tool. For more information about GeoServer please see: http://docs.codehaus.org/display/GEOS/What+is+Geoserver The release can be downloaded at: http://docs.codehaus.org/display/GEOS/Stable The GeoServer Project is completely open source, in license and development process, built by an open community of contributors. Please see: http://docs.codehaus.org/display/GEOS/Contributors for a list of everyone that makes GeoServer possible. If you are interested in helping out, even with just suggestions on how to make it better, don't hesitate to show up on our lists at: http://sourceforge.net/mail/?group_id=25086 All fixed issues for 1.3 can be found at: http://jira.codehaus.org/secure/IssueNavigator.jspa?mode=hide&requestId=11511 -------------- next part -------------- A non-text attachment was scrubbed...

Alternativly there is Mapserver http://mapserver.gis.umn.edu/ which works nicely but is harder to set up. Both of these eaxmples will allow you to publish your data as an image using the OGC web map server protocol and as features using the OGC web feature server protocol. Since these are open standrds you can use a variety of clients to view the data. If you need to put the images on a web page then I'd recomend Mapbuilder (http://mapbuilder.codehaus.org/) or Ka-map ( maptools.org).

Nico, There are WCS servers providing elevation data for the world that you could query. I run an SRTM30 server, but that is pretty coarse data. What degree of spatial precision were you needing? http://maps.gdal.org/ WCS can be queried from from PHP, but the return result (at least of my server) is a raster file which might be hard for you to extract the value from. In theory I could enable "WMS getfeatureinfo" style query from the raster data on the corrsponding WMS service and then you would get a small GML document. But I'm not sure how hard that would be to get working.

Nico, In my case, the SRTM30 data is on 30second postings. I elieve that works out to a roughly 1km grid. So only 100th the data of 100m spacing. It is still a 2GB file uncompressed and with overviews built. > These WCS servers cannot be queried for single points?

This could become the backbone to such a query which is simply the 'r.what' command in GRASS. Wrapping 'r.what' in SWIG, a SWIG-PHP interface could do what you need.

Already available is the first draft of the version gvSIG 0.6-rc1, it can be found under http://www.gvsig.gva.es/ingles/descargasw/descarga_software.htm (Downloading the program). Hereby, we would like to encourage you to participate in this project by informing us about any detected error, simplest way by the means of the e-mail distribution list. Definitely, we appreciate every kind of feedback and suggestion. New features of this version: Web Services (OGC) - The clients of two new web services are integrated: o Catalogue Service: In a Spatial Data Infrastructure, this is a basic service that helps to search and find cartographic data o Nomenclature Service (Gazetteer): Helps to localise positions on the basis of toponymy and geographic names - Several features of the WMS client have been improved: o More user-friendly interface o Complete information about every layer of the WMS server o Style formatting o Support of temporal dimensions o Possibility to configure the intern order of the layer rendering process o Layers of the table of contents are manageable from the context menu Supported data formats: -The feature “Export to raster” supports two new data formats: o jpeg (georeferenced) o jpeg2000 (georeferenced) Raster layers: -The pansharpening tool helps to increase the resolution of satellite images, if they are panchromatic. Type of data sources: -It is possible to create layers on the basis of a table that contains coordinates. The resulting layer will contain a point for every pair of coordinates. Furthermore, any change of the table coordinates will modify automatically the position of the points. We count on your collaboration.

As fas as I can see, there is currently no public Web Service or public server API available, I would have to install GRASS and implement my own web service or extend the SWIG API... What seems strange to me is, that requests which return a raster file are possible but quite more simple requests for just one property of a single point aren't availabe. There has to be some kind of data base in the back bone, where the datas for single points are stored and it cannot be so difficult to query this data base... Anyway, I'm not experienced with geo data at all and so maybe I misunderstand the principals. Since I want to publish the tool as extension for an OpenSource CMS (Typo3) it doesn't make sense to include an application which has to be installed on a web server. I can only include the elevation data if there is some public access to such data, which seems not to be the case...

It seems to be some weeks old, but was new to me (and haven't found any discussions about it). The interesting part is, that they speak about some great improvements (and even competition) of VMAP1 data, but one can't really understand weather or not now all CD's will be available (very weired). But read for yourself: http://www.nga.mil/NGASiteContent/StaticFiles/OCR/nga0602.pdf International Partnership Completes Decade-Long Conversion to Worldwide, Digital Vector Data BETHESDA, Md.?With the recent completion of the decade-long Vector Map Level 1 program, geospatial analysis efforts worldwide received a significant boost. An international effort, led by the National Geospatial-Intelligence Agency, collected vector data?the digitized points, lines and polygons representing features on Earth?to create the best available standardized data of its kind. Analysts use vector data for high-level analysis and cartographic products. Standardized data enables users worldwide to work from a common reference point. VMap1 data separates into thematic layers?or coverages?with all the data topographically?or smartly?structured. Available data includes boundaries, elevation, hydrography, industry, physiography, population, transportation, utilities and vegetation. The Defense Logistics Agency distributes this data to the U.S. military on CDs, while publicly releasable data is available on the Internet and through the Geospatial-Intelligence Feature Database. Cooperation among the international geospatial community, including contract and government employees of Australia, Belgium, Canada, Czech Republic, Denmark, France, Germany, Greece, Italy, Netherlands, New Zealand, Norway, Poland, Portugal, Spain, Sweden, Turkey, United Kingdom and Unites States, made the project possible. New Zealand-produced data aided in tsunami recovery and relief efforts in Southeast Asia. Additional data is assisting relief efforts in Pakistan. Another project data set formed the basis of a Northern Italy Reference graphic instrumental in planning efforts for the upcoming Winter Olympics in Turin. The program?known as VMap1?responded to the needs of the geospatial industry. In the early 1990s, the industry shifted from the production of static paper maps to the direct digital input of dynamic information into geographic information systems. With the delivery of the final CD (of 234 total) in December 2005, NGA and its international co-producers and contractors completed a 12-year project providing near-global coverage. Marzio Dellagnello of NGA?s Global Foundation Office led the Vector Map Co-Production Working Group team responsible for the production and provision of VMap1 data and products. ?Scanned paper maps provided most of the source data for the project,? said Dellagnello, who worked on the project from its inception. His team provided quality control of the data. An off-shoot of the project is the Multinational Geospatial Co-Production Program, a five-year, international effort to further the cooperation and success of the VMap1 project. MGCP will produce a series of higher resolution vector data sets, and has increased the number of participating countries from 19 to 28. (VMap1 data specifications are for a 1:250,000 scale, while MGCP?s goal is 1:50,000 to 1:100,000.) NGA is a Department of Defense combat support agency and a member of the National Intelligence Community. The Agency?s mission is to provide timely, relevant and accurate geospatial intelligence in support of our national security. Headquartered in Bethesda, Md., NGA has major facilities in the Washington, D.C., Northern Virginia and St. Louis, Mo., areas with NGA support teams worldwide.

The Geographic Resources Analysis Support System, commonly referred to as GRASS GIS, is a Geographical Information System (GIS) used for data management, image processing, graphics production, spatial modeling, and visualization of raster, vector and sites data. It is open source Free Software released under the GNU General Public License (GPL). The new features of GRASS 6 cover a new topological 2D/3D vector engine and support for vector network analysis. Attributes are now managed in an SQL-based DBMS. A new display manager has been implemented. The NVIZ visualization tool was enhanced to display 3D vector data and voxel volumes. Messages are partially translated (i18N) with support for FreeType fonts, including multibyte Asian characters. New LOCATIONs can be auto-generated by EPSG code number. GRASS is integrated with GDAL/OGR libraries to support an extensive range of raster and vector formats, including OGC-conformal Simple Features. GRASS is founding member of the new Open Source Geospatial Foundation. Platforms supported by GRASS: GNU/Linux, Sun Solaris (SPARC/Intel), Silicon Graphics Irix, Mac OS X/Darwin, Microsoft Windows with Cygwin, HP-UX, DEC-Alpha, AIX, BSD, iPAQ/Linux and other UNIX compliant platforms (32/64bit). Software download/CDROM: * http://grass.itc.it * http://grass.ibiblio.org * and various mirror sites The new source code is available now, and selected binary distributions for major operating systems will be published shortly.

Where can I get them? Ari, the files are not on this page because they are stored in GRASS-CVS. But I have added related links now (thanks for the suggestion): http://mpa.itc.it/markus/grass61progman/swig/main.html > In fact I think I'd like to continue on this work a bit. I've tried to > think a way to get Grass' capability to my Perl-CLI/GUI, and probably > working on this is the best way. I'd like to create some kind of > translator, which would make Grass command line functions easy to wrap > with Swig. Sounds great. There is one thing which I discussed with Howard Butler at Chicago recently: The GRASS code should not be replicated in the SWIG interface. This will require changes in the GRASS code, in a sense, that main procedures (parameter definitions etc) are separated from the real algorithm. This is unfortunately not the case for the example (r.slope.aspect). I am happy to get suggestions how to change the code in GRASS to be easier/better wrapped with SWIG. > Can Grass use geodata via GDAL? Or is it only the other way around, > i.e., GDAL can open Grass data? Both, I think: - GRASS imports external data via GDAL/OGR (r.in.gdal/v.in.ogr) - GDAL/OGR can read data via GDAL-OGR-GRASS plugin So it may be an idea to wrap r.in.gdal and/or v.in.ogr into GRASS-SWIG. The someone could remotely import data (even create a new "location" which is the GRASS project) and work on these data from outside via SWIG. Results can be read directly via GDAL-OGR-GRASS plugin, e.g. in Mapserver. Like this GRASS operates as GIS analysis backbone.

I'm hoping that it is possible to write a translator, which automates this step, i.e., the example r_slope_aspect.c would be generated with that translator. If it needs a full C parser, then it gets complicated however. It's a bit similar to what Swig itself does when it creates the wrapper C code. > >> Can Grass use geodata via GDAL?

The ultimate tool would also have R spatial capabilities among other things... The problem is how to move the data from one environment to the other. Probably that could be organized through GDAL/OGR, i.e., all tools may have their native formats but should include GDAL/OGR i/o.

I always wanted to look at the R to C interface (embedded R or however that's called to launch R tasks from the GRASS side).
