# v.what.strds(1grass)

Uploads space time raster dataset values at positions of vector points to the table.

## NAME

**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 population \>= 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.

## EXAMPLES

```
v.what.strds input=mypoints strds=mystrds output=newvector
```
