v.in.mapgen: allow direct input from stdin
|Reported by:||hamish||Owned by:|
it would be nice if v.in.mapgen could read directly from stdin when 'input=-'.
in "matlab" format mode this module can make a vector line map from a two column "x y" data-stream, with new lines created whenever a "nan nan" is in the stream. this is very useful for creating a line from points without bothering with the grass vector ascii format. it might be worth getting its own wrapper script as the 'v.in.mapgen -f' command is not obvious for this generic task. v.in.points_as_lines or ...?
