= Temporal GIS Algebra for Raster and Vector Data = The idea is to implement a temporal GIS algebra to process space time datasets of type raster and vector,  the new spatio-temporal datatypes in GRASS GIS 7. Space time datasets represent time series of raster, 3D raster and vector maps.  The GRASS GIS temporal framework implements a snapshot approach,  so that time and space are separated from each other.  Hence, space time datasets are not truly 4 dimensional datatypes, time and space can only be processed separately from each other. The spatial capabilities of GRASS GIS are used to perform the spatial  processing of the time stamped maps that are registered in the space time datasets.  We use the modules r.mapcalc for raster processing and v.buffer, v.overlay, v.patch for vector map processing in the algebra.  The temporal processing is provided by the GRASS GIS temporal framework that supports time intervals and time instanc...
