The presentation describes the new GRASS 5.1 vector library architecture. This new architecture overcomes the vector limitations of GRASS 4.x-5.0 by extending the vector support with attributes stored in external relational databases and by new 3D capabilities. Besides internal file based storage the geometry may alternatively be stored in PostGIS database. This enables users to maintain large data sets with simultaneous write access. External GIS formats such as SHAPE-files may be used directly without necessity of format conversion

Abstract

The presentation describes the new GRASS 5.1 vector library architecture. This new architecture overcomes the vector limitations of GRASS 4.x-5.0 by extending the vector support with attributes stored in external relational databases and by new 3D capabilities. Besides internal file based storage the geometry may alternatively be stored in PostGIS database. This enables users to maintain large data sets with simultaneous write access. External GIS formats such as SHAPE-files may be used directly without necessity of format conversion
