| @RyanWhitley To convert polygons to polylines in GRASS: | |
| v.in.ogr dsn=<input>.shp out=chad | |
| v.build.polylines in=chad out=chad2 | |
| v.out.ogr type=boundary in=chad2 dsn=grass_chad_lines.shp | |

| @RyanWhitley Here's how you can do it to lines: | |
| v.in.ogr dsn=AdminLine2.shp out=chad | |
| v.clean tool=rmdupl in=chad out=chad2 <--new step to remove dupe segments | |
| v.build.polylines in=chad2 out=chad3 | |
| v.out.ogr type=line in=chad3 dsn=grass_chad_lines.shp <-- note "type" is "line", not "boundary" |
