I downloaded some shapefiles from the Australian Bureau of Statistics (ABS). It's basically showing a bunch of suburbs when I view the shapefile through a GIS tool. The GIS tool that I am using at present is the GRASS 6.4.2 tool.
So basically the shapefile has the below statistics
Number of points: 0 Number of areas: 15231 Number of lines: 0 Number of islands: 7003 Number of boundaries: 31362 Number of faces: 0 Number of centroids: 15220 Number of kernels: 0I'm trying to extract from this shape file the arcs. That is the polylines of the boundaries. This is because I need to find for each arc its accompanying adjacent boundary.
For example arc1 may have boundary with Cat id - 135 on its left and Cat ID = 125 on its right.
Any clues as to how to do this would be appreciated.
