GRASS 6.0 features
The improvements of the vector architecture cover the new 3D
multiattribute, multilayer vector library, a modified NVIZ and a few
database management tools. DBMS is now integral part of the system.
- New Vector Engine (geometry):
-
Support for 2D/3D vectors (see screenshot)
(CAD drawings, TINs), visualization supported in NVIZ
multiformat - also virtual map supported from external data
sources (SHAPE-file, PostGIS) without the need of data conversion
(through OGR library with 'v.external');
-
Export/Import to PostGIS;
-
spatial index build on the fly - 'v.build' (was: v.support)
significantly accelerated;
-
category index to accelerate attribute queries;
Database Management Interface (attributes):
-
Attribute storage in DBMS for compatibility with industry standards
(SQL based interface for PostgreSQL, mySQL, ODBC, dBase)
-
multiattribute - attributes saved in dBase files (default) or
saved in external DBMS
-
multilayer - features in one vector may represent one or several
layers and may be linked to one or many external tables
-
forms library implemented for user friendly query dialogs
-
Linear reference systems supported (LRS, yet to integrate)
Applications/Misc:
- SQL queries/selects/extractions supported by vector modules
- interactive attributes updating is supported through the forms library
(d.what.vect lets you modify directly the attached attributes)
-
Vector network analysis:
Shortest path, Traveling salesman (round trip), Allocation of sources
(subnetworks), Minimum Steiner trees (starlike connections),
and isodistances (from centers)
(e.g. shortest path, see
screenshot) - based on
DGLIB (Directed Graph Library), costs may be assigned
both to nodes and arcs (and also different in both directions of a vector
line)
- new v.digit with GUI (screenshot)
- import and export of any OGR supported
vector format (Shapefile, TIGER, MapInfo and GML2, PostGIS and DGN)
- GUI generated on runtime and display
manager (screenshots)
- i18n: support for multiple languages (messages partially indicated and
translated)
- multiple GRASS sessions: a user can start more than one session
at the time
Interoperability
- Raster and vector data interoperability is granted through the GDAL/OGR
libraries which implement interfaces to OGC standards and common GIS data formats
Volume visualization
Large File Support for raster maps
Experimental!
- GRASS 6.0 experimentally supports reading and writing large files (> 2GB, LFS support)
if it is possible in your operating system. If you compile with
-D_FILE_OFFSET_BITS=64, you should be able to have raster maps
which are larger than 2Gb. Note that the support currently only applies
to the core raster I/O code. Individual programs may or may not work
with large files - please report.

GRASS 6.0 development
- Description of new vector engine:
- Compiling own GRASS 6.0 modules or changed modules:
simply run "make" in the appropriate directory
and "make install" in the top source directory (or read INSTALL for a simpler method).
- Further delopment tasks:
- Code cleanup, clones removal, etc.
- GRASS as Web server application (client/server architectures)
- GRASS/QGIS integration.
