[GRASSLIST:4667] from line to polygon

Hi GRASS friends,

I am very new in using GRASS (5.3, 5.7, LINUX). I have two questions:

1) I have a line-Shape-file, in which areas (vegetation types) are digitized. After importing into GRASS, is it possible to convert the lines into polygones?

2) Is it possible to export these polygones in Arc/Info-e00-format?

Thanks with greetings from Tyrol

Hi Helli,

   I guess that in GRASS 5.3 you could use

1) v.line2area
2) v.out.e00

  I'm not sure about how to do it in GRASS 5.7

Use v.type:

Convert lines to area boundaries
v.type input=map_l output=map_b type=line,boundary

To make it polygons, you will have to add centroids.
