if the node id is lower than the first node in the data file, then server throughs an error:

Other tests:

If the node id is larger than the largest id in the file, it does not respond (endless loop).

If the way id is lower than the lowest id in the file, server is i.O.

If the way id is larger than the largest id in the file, it does not respond (endless loop).

If the relation id is lower than the lowest id in the file, server is i.O.

If the relation id is larger than the largest id in the file, it does not respond (endless loop).

python -m osm.multipolygon -r 1111111

In order to use python-osm, some documentation, ideally containing lots of useful examples, would be useful.

One example (which I figured out myself):

To export relation with id=62578 as polygon file for osmosis:

multipolygon.py -r 62578 -m boundary.poly

with matplotlib 1.4.2 i got following error:

Traceback (most recent call last):
  File "./places.py", line 9, in 
    from osm import multipolygon
  File "python-osm/src/osm/multipolygon.py", line 6, in 
    import matplotlib.nxutils
ImportError: No module named nxutils

Due to the numpy changes the version id in the osmhistory data is not the latest.
Thus the data can not be used to revert osm changes.

A special setter function is needed in pyosm.py.

Zum Reproduzieren:

python -m osm.multipolygon -r 27027

Bei mir kommt der Fehler

hi,
i've got error
"KeyError: -1426996844"
maybe change "int" into "long" ?

Zum Reproduzieren:

python -m osm.multipolygon -r 450512

Die Relation hat offensichtlich einen Knoten, in dem sich zwei Polygone (und insgesamt 4 ways) berühren. Siehe
