Geographic Resources Analysis Support System (GRASS GIS) is a geographic information system used for data management, image processing, spatial modeling, and visualization of many types of data. It is Free Software released under GNU (GNU is Not Unix!) General Public License (GPL). Besides GRASS GIS, there are available many Open Source GIS-based software packages which are widely used, e.g. UMN MapServer, QGIS, GDAL/OGR, JUMP, GeoTools. Many of the tools can be combined to build interoperable high level applications. Some of the listed projects are using GRASS directly as GIS back-end. This presentation illustrates new directions mainly related to GRASS GIS with some extensions to GFOSS (Geographic Free and Open Source Software) in general. We will describe the use of GRASS GIS and other GFOSS packages for the Web Processing Service (WPS) standard as defined by Open Geospatial Consortium (OGC). The WPS standard describes the way how geospatial operations can be served across computer networks. Here geospatial computations (data interpolation, buffering, etc.) are performed by the server. This implies that no client side desktop GIS installation is needed. A second topic is the import and processing of cadastral data in GRASS (referred to the Czech cadastral exchange data format). The abstraction level in these cadastral data makes its processing in GIS more challenging. In any case, GRASS was partially modified to become usable for processing and visualization of cadastral data. We will also discuss new methods for generating 3D vector data for virtual tree/forests and for extruding of 3D buildings in GRASS. Furthermore, using GNU GaMa (the project dedicated to adjustment of geodetic networks) with GRASS GIS (in particular converting GaMa XML output file to a GRASS vector map) is shown. In the conclusions of the presentation, general ideas about GRASS GIS development will be shared, especially in connection with new GUI (Graphical User Interface). New approach of GRASS GUI (digitization, map composer, etc.) will probably be Python based. We introduce the GRASS module v.edit which allows users to edit vector map layer via command line interface. This new module will be used in the future as a back-end for the new GUI-based digitization tool in GRASS.
