-
Name of input file in Mapgen/Matlab format - output=name
-
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.
