v.what.strds — Uploads space time raster dataset values at positions of vector points to the table.

Keywords

vector, temporal, sampling, position, querying, attribute table, time

Synopsis

v.what.strds
v.what.strds --help
v.what.strds [-u] input=name strds=name[,name,...] [output=name] [where=sql_query] [t_where=sql_query] [--overwrite] [--help] [--verbose] [--quiet] [--ui]

Flags

-u
Update attribute table of input vector map
Instead of creating a new vector map update the attribute table with value(s)
--overwrite
Allow output files to overwrite existing files
--help
Print usage summary
--verbose
Verbose module output
--quiet
Quiet module output
--ui
Force launching GUI dialog

Parameters

input=name [required]
Name of input vector map
Or data source for direct OGR access
strds=name[,name,...] [required]
Name of the input space time raster datasets
output=name
Name for output vector map
where=sql_query
WHERE conditions of SQL statement without ’where’ keyword
Example: income < 1000 and inhab >= 10000
t_where=sql_query
WHERE conditions of SQL statement without ’where’ keyword used in the temporal GIS framework
Example: start_time > ’2001-01-01 12:30:00’

Description

v.what.strds retrieves raster values from a given space-time raster datasets (STRDS) using a point vector map.

Notes

TBD.
