Hanan Samet Cyrus Shahabi Markus Schneider Co-general Chair Co-general Chair Program Chair ------------------------------------------ 15th International Symposium on Advances in Geographic Information Systems Call for Participation ------------------------------------------ November 7-9, 2007 Seattle, Washington, USA In cooperation with ACM SIGMETRICS Sponsored by Microsoft, ORNL, Google, and ESRI http://www.cise.ufl.edu/dept/acmgis2007/ The ACM International Symposium on Advances in Geographic Information Systems in 2007 (ACM GIS 2007) is the fifteenth event of a series of symposia and workshops that began in 1993 with the aim of bringing together researchers, developers, users, and practitioners carrying out research and development in novel systems based on geo-spatial data and knowledge, and fostering interdisciplinary discussions and research in all aspects of geographic information systems. 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. ACM GIS will have two invited speakers, 37 full papers and 29 poster papers (see below). ================ Invited Speakers ================ Michael T.

Tim, At the risk of self promotion, I would suggest TIFF or GeoTIFF. It is reasonably widely supported in the geospatial world and should be sufficient to represent single or double precision floating point data. Of course there are lots of packages that don't support it too. I'm not sure that OGC speaks very directly to file formats (other than GML!) but certainly GeoTIFF is reasonably widely used in OGC services like WCS.

This is a bug fix release in the 1.4.x stable release series and adds no significant new features. This release replaces the GDAL/OGR 1.4.3 release which has been retracted by the project as it included an unexpected ABI (Application Binary Interface) change from the earlier 1.4.x releases. This ABI change means that applications using the GDAL/OGR C++ interface, and GDAL/OGR driver plugins built against GDAL/OGR 1.4.0, 1.4.1 or 1.4.2 could not be safely used with GDAL/OGR 1.4.3. All applications redistributing binaries are encouraged to discard GDAL/OGR 1.4.3 and use 1.4.4 instead. The GDAL/OGR 1.4.4 release is ABI compatiable with all earlier 1.4.x releases except for the disavowed 1.4.3. GDAL/OGR 1.4.4 is available in source format at: http://download.osgeo.org/gdal/gdal-1.4.4.tar.gz http://download.osgeo.org/gdal/gdal144.zip More detailed NEWS on fixes in the 1.4.4 release can be found at: http://trac.osgeo.org/gdal/wiki/Release/1.4.4-News GDAL 1.5.0, a major "new features" release, will be entering beta during December, and it is hoped a GDAL 1.5.0 release will be available by the end of year.

If you data has a hierarchical > format, hdf5. Lots of 3rd party tools for these. What I thought yesterday when looking at the gdal list of formats at [1] was using either netCDF or GMT netCDF. Buth then I read that "GDAL has limited support for reading general netCDF files. NetCDF support in GDAL is optional, and not compiled in by defaut" That would mean that I still have the data in a format which can't bea read by FOSSGISS programs without additional effort. Well, at least GRASS seems to understand that format: http://grass.gdf-hannover.de/wiki/GRASS_and_GMT But there's no support by gvSIG and other easier to use desktop GIS that I can recommend my collegues for viewing the results of the calculations. I found some more links using google on that: [2], [3]. I seams that netCDF-suppport is not yet well implemented in most GI systems. If anyone knows more I welcom your hint!

TIA, Yves Moisan From neteler at fbk.eu Thu Nov 29 18:31:53 2007 From: neteler at fbk.eu (Markus Neteler) Date: Thu, 29 Nov 2007 18:31:53 +0100 Subject: [Freegis-list] GRASS GIS 6.2.3 released Message-ID: <20071129173153.GA19376@fbk.eu> For Immediate Release GRASS GIS releases version 6.2.3 27 November 2007 http://grass.osgeo.org The development team is happy to announce that a new bugfix version of GRASS GIS has been released today. This release fixes a number of bugs discovered in the 6.2.2 source code. It is primarily for stability purposes and adds minimal new features. Besides bug fixes it also includes a number of new message translations and updates for the help pages and projection database. Highlights include further maturation of the GRASS 6 GUI, vector, and database code. Some improvements have been backported from the GRASS 6.3 development branch where new development continues at a strong pace of approximately one code commit every hour, including major work on an all new cross-platform wxPython GUI and a native MS Windows port. The Geographic Resources Analysis Support System, commonly referred to as GRASS, is a Geographic Information System (GIS) combining powerful raster, vector, and geospatial processing engines into a single integrated software suite. GRASS includes tools for spatial modeling, visualization of raster and vector data, management and analysis of geospatial data, and the processing of satellite and aerial imagery. It also provides the capability to produce sophisticated 4D presentation graphics and hardcopy maps. GRASS is currently used around the world in academic and commercial settings as well as by many governmental agencies and environmental consulting companies. It runs on a variety of popular hardware platforms and is Free open-source software released under the terms of the GNU General Public License. GRASS is a proposed founding project of the new Open Source Geospatial Foundation. In support of the movement towards consolidation in the open source geospatial software world, GRASS is tightly integrated with the latest GDAL/OGR libraries. This enables access to an extensive range of raster and vector formats, including OGC-conformal Simple Features. GRASS also makes use of the highly regarded PROJ.4 software library with support for most known map projections and the easy definition of new and rare map projections via custom parameterization. Strong links are maintained with the QuantumGIS and R Statistics projects with integrated GRASS toolkits available for both.
