## DESCRIPTION

t.info reports informations about any dataset that is registered in the temporal database in human readable or shell script style. Datasets are raster, 3D raster and vector maps as well as their corresponding space time datasets (STRDS, STR3DS and STVDS). This module reports the informations that are stored in the temporal database. These are basic informations (id, name, mapset, creator, creation time, temporal type), the temporal and spatial extent and dataset type specific metadata. The user has to utilize r.info, r3.info, v.info to report detailed informations about raster, 3D raster and vector maps, since not all map specific informations and metadata are stored in the temporal database.

In addition, informations about the chosen temporal database backend can be reported.

## EXAMPLE

In this example we first report temporal database backend information using t.info -s. Then we create a single raster maps using r.mapcalc with random values that will be registered in a single space time raster dataset named precipitation_daily using a daily temporal granularity. We use t.create for the space time raster dataset creation and t.register to register the raster map in the space time raster dataset. At the end we report informations about the raster map and the space time raster dataset to stdout.
