DESCRIPTION

47       v.in.mapgen allows the user to import Mapgen or Matlab vector maps into
48       GRASS.
49

NOTES

51       This module only imports data into vector lines.
52
53       The  user can get coastline data in Mapgen or Matlab format from NOAA’s
54       Coastline Extractor  at  http://www.ngdc.noaa.gov/mgg/shorelines/shore
55       lines.html.
56
57       Matlab vector line maps are simply a series of "x y" data points. Lines
58       are separated by a row containing NaN NaN.   Output  from  Matlab  with
59       this command:
60           save filename.txt arrayname -ASCII
61
62       The  user can import 3D lines from Matlab by exporting a 3 column array
63       and using the -z flag.
