NAME
v.sort.points - Sorts a vector point map according to a numeric column
KEYWORDS
SYNOPSIS
v.sort.points
v.sort.points --help
v.sort.points [-r] input=name layer=string output=name column=name [--overwrite] [--help] [--verbose] [--quiet] [--ui]
Flags:
- -r
- do not reverse sort
- --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
- layer=string [required]
- Layer number or name
- Vector features can have category values in different layers. This number determines which layer to use. When used with direct OGR access this is the layer name.
- Default: 1
- output=name [required]
- Name for output vector map
- column=name [required]
- Name of attribute column used for sorting
v.sort.points takes an
input point vector map, sorts
the points by the values in the sort
column and then writes
the result to the
output map.
This is useful to display symbols in sizes proportionate to that same
column without having big symbols hide small symbols.
By setting the r flag, the user can also chose to reverse the
sorting order putting points with the highest value in front.
