NAME¶

v.in.mapgen - Imports 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. The user 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 The user can import 3D lines from Matlab by exporting a 3 column array and using the -z flag.
