I can't figure out how to solve a problem with a line feature shapefile I have. It has been wrongly created as 81 single lines touching each other with their vertexes. I need to merge the lines into a unique line. I've tried with v.edit and the merge tool, two times. First time it gave me 32 lines, the second I receive the following result:
1 of 4 features selected from vector map <[EMAIL PROTECTED]> Only 1 lines found, at least two needed -1 lines merged Building topology ... Registering lines: 4 primitives registered Building areas: 0 areas built 0 isles built Attaching islands: Attaching centroids: Topology was built. Number of nodes : 5 Number of primitives: 4 Number of points : 0 Number of lines : 4 Number of boundaries: 0 Number of centroids : 0 Number of areas : 0 Number of isles : 0 v.edit complete. I can't understand what it means: it says it selected 4 lines but then just 1 line has been found. the post build report lists 4 lines... I'm a bit confused. I've manually merged all the categories too with v.digit, but nothing seems to change (neither better nor worst!). What am I doing wrong? What's the best method to achieve my task? Thanks, Giovanni
