Description
The module t.topology lists temporal relations of the maps in a space time dataset.
Example
In order to obtain information about space time dataset topology, run:
t.topology tempmean_monthly@climate_2009_2012 +-------------------- Basic information -------------------------------------+ | Id: ........................ tempmean_monthly@climate_2009_2012 | Name: ...................... tempmean_monthly | Mapset: .................... climate_2009_2012 | Creator: ................... lucadelu | Temporal type: ............. absolute | Creation time: ............. 2014-11-28 10:40:55.060096 | Modification time:.......... 2014-11-28 16:08:42.166628 | Semantic type:.............. mean +-------------------- Temporal topology -------------------------------------+ | Is subset of dataset: ......
