SYNOPSIS
t.rast.out.xyz
t.rast.out.xyz --help
t.rast.out.xyz [-i] strds=name [output=name] [where=sql_query] [separator=character] [--overwrite] [--help] [--verbose] [--quiet] [--ui]
Flags:
- -i
- Include no data values
- --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:
- strds=name [required]
- Name of the input space time raster dataset
- output=name
- Name for the output file or "-" in case stdout should be used
- Default: -
- 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'
- separator=character
- Field separator
- Special characters: pipe, comma, space, tab, newline
- Default: pipe
The t.rast.out.xyz module exports a space time raster dataset as a list
of x,y,z values into an ASCII text file.
By default, this module does not export x,y coordinates for raster cells
containing a NULL value. This includes cells masked by a raster MASK.
However, using the flag
-i also these raster cells will be included in
the exported data.
t.rast.out.xyz is simply a front-end for "
r.out.xyz".
# export strds without NULL cells
t.rast.out.xyz strds=mystrds output=/tmp/mystrds.csv
# export strds including NULL cells and for a certain time period
t.rast.out.xyz -i strds=mystrds output=/tmp/mystrds.csv \
where="start_time > '2010-01-01 00:00:00'"
r.out.xyz,
