57 Description of the new space time dataset
58
60 t.create is used to create space time datasets of type raster (STRDS),
61 3D raster (STR3DS) and vector (STVDS).
62
63 Space time datasets represent spatio-temporal fields in the temporal
64 GRASS framework. They are designed to collect any amount of time
65 stamped maps with time intervals and time instances. The temporal type
66 of a space time dataset can be absolute (means with a fixed date) or
67 relative (only sequential maps) and must be set during dataset creation
68 along with the name and the description.
69
70 Time stamped maps can registered in and unregistered from space time
71 datasets. The spatio-temporal extent as well as the metadata of a space
72 time dataset is derived from its registered maps. Hence the metadata is
73 dependent from the dataset type (raster, 3D raster, vector).
