1README for merge-ways
2---------------------
3
4merge-ways is intended as a preprocessor for certain rendering or other actions
5performed on OSM files.
6
7It finds adjoining ways and merges them into one way provided they share certain
8characterstics. Which characterstics these are is expressed in a function at the
9top of the script.
10
11It does not yet handle relations (might even break them by removing a way that
12was used by a relation).
13
14Another known bug is that it will happily join the opposing lanes of a dual carriageway
15if they meet at an intersection, often leading to the street name written in a 180
16degree bend around the end of the street.
17
18The primary use is as a preprocessor for Osmarender when streets are split in many
19ways, none of which large enough to contain the street name.
