v.in.mapgen allows the user to import Mapgen or Matlab vector maps into
GRASS.
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.
