NAME
v.in.mapgen - Import Mapgen or Matlab-ASCII vector maps into GRASS.
KEYWORDS
vector, import
SYNOPSIS
v.in.mapgen
v.in.mapgen help
v.in.mapgen [-fz] input=string [output=string] [--overwrite] [--verbose] [--quiet]
Flags:
- -f
- Input map is in Matlab format
- -z
- Create a 3D vector points map from 3 column Matlab data
- --overwrite
- Allow output files to overwrite existing files
- --verbose
- Verbose module output
- --quiet
- Quiet module output
Parameters:
- input=string
- Name of input file in Mapgen/Matlab format
- output=string
- Name for output vector map (omit for display to stdout)
DESCRIPTION
v.in.mapgen allows the user to import Mapgen or Matlab vector maps
into GRASS.
NOTES
This module only imports data into vector lines.
You can get coastline data in Mapgen or Matlab format from NOAA's Coastline
Extractor at http://www.ngdc.noaa.gov/mgg/shorelines/shorelines.html.
Matlab vector line maps are simply a series of "x y" data points. Lines
are separated by a row containing NaN NaN.
Output from Matlab with this command:
save filename.txt arrayname -ASCII
You can import 3D lines from Matlab by exporting a 3 column array and
using the -z flag.
