GRASS 6.4.0, the new stable release after more than one year of development and testing, brings a number of exciting enhancements to the GIS. Besides the hundreds of new module features, supported data formats, and language translations, GRASS 6.3 brings a number of exciting enhancements to the GIS. A prototype of the new wxPython user interface is debuted, and for the first time since its inception with a port from the VAX 11/780 in 1983, GRASS will run on a non-UNIX based platform: MS-Windows. This is currently still in an experimental state and we hope that widespread testing of 6.3.0 will mean the 6.4 release of WinGRASS will be fully functional and robust. Existing UNIX and Mac users will be happy to know that these new features do not disrupt the base GIS which remains as solid as ever and fully backwards compatible with earlier GRASS 6.0 and GRASS 6.2 releases.

Several infrastructure changes accompany this release with the project becoming a founding member of the Open Source Geospatial Foundation (OSGeo). This includes a new home for the website, the Wiki help system, source code repository, community add-on module repository, integrated bug tracking system, and formal membership for the project in a non-profit legal entity. We hope that these changes will guarantee that the GRASS community will be well supported and vibrant well into the future.

  • Over the past decade free and open source software (FOSS) has moved into mainstreem and its growth includes a wide range of geospatial software tools. The presentation will briefly describe the principles of FOSS and provide an overview of major FOSS projects that support management, processing, analysis, visualization and on-line distribution of georeferenced data. Interoperability between the different tools enabled by the FOSS concept will be highlighted using examples of applications that combine software developed by several projects, such as GRASS, Mapserver, GDAL, PROJ, R-stats, PostGIS, paraview and others. Special focus will be given to the recent new developments in Geographic Resources Analysis Support System (GRASS, ). Since its original design as a land management tool for military installationsthe system has evolved into one of the most comprehensive, general purpose GIS and support for environmental modeling has been an integral part of its development. Overview of the GRASS6 capabilities relevant to environmental modeling will be provided, including tools for working with 2D and 3D raster data, the completely redesigned topological 2D/3D vector engine, vector network analysis and SQL-based attribute management. Various graphical user interfaces, such as QGIS and JAVAGRASS, that are being used with GRASS will be introduced and enhancements to 3D dynamic visualization will be presented. Environmental modeling will be illustrated by examples in the area of coastal management and sediment pollution control using the latest lidar data and new or updated GRASS6 modules. The talk will conclude with discussion of visions for the future of FOSS geospatial modeling.
