    v385 v386  
    206206The [http://grass.osgeo.org/grass70/manuals/temporalintro.html new temporal GRASS GIS 7 framework] has been developed to manage, process and analyse large scale, spatio-temporal environmental data. In detail, the framework supports querying and map calculation of spatio-temporal data, aggregation, statistics and gap filling, and data export, import, and conversion. A spatio-temporal topology builder is available to build spatio-temporal topology connections between map objects for 1D, 3D and 4D extents. The topology creation is based on the R*Tree implementation in the vector library which supports even 4D extents.
