Good day, everyone
When I try to export an polygon's coverage
as ARC/INFO generate, Grass exports the
segments of the polygon, but not the
correct secuence of vertexes of the polygon,
neither the correct id of that polygon,
so I can not re-create the coverage out from
Grass.
The generate format for polygons is like:
ID
coord x of the first vertex,coord y of the first vertex
coord x of the second vertex,coord y of the second vertex
coord x of the third vertex,coord y of the third vertex
..
..
coord x of the nth vertex,coord y of the nth vertex
coord x of the first vertex,coord y of the first vertex
END
For example:
1
200.00,150.00
300.25,236.28
254.35,498.25
456.87,548.24
200.00,150.00
END
2
325.25,365.25
365.25,547.56
658.78,659.85
325.25,365.25
END
How could I get that?
Or how can I manipulate the script?
Or how can I manipulate the drawing
in order to write the file
the way I need?
Thank you,
Jaime Mejía.
