<font face="Verdana">yes, this method takes care of multiple boundary
lines. this method always gets us one way belonging to several relations</font>.<br>
<br>
i'm not sure if we can fix the already imported boundaries with some
kind of script automatically. as i said, i corrected himachal yesterday
(by hand), all the way down to district level, took me around 3h.<br>
<br>
the process is quite easy and quick (supposing you know your way around
josm):<br>
* split the existing border ways (the data is good, as far as i can
see) in the appropriate places<br>
* remove duplicate lines<br>
* tag the remaining border ways correctly<br>
* build the relationes and add the appropriate border ways <br>
<br>
btw, the shimla district looks odd to me, the data on osm suggests that
shimla town is actually an "island" in solan district. is that correct?
can anyone with more local knowledge than me check? and fix, if needed?<br>
<br>
regards, m.<br>

<font face="Verdana">we'll need relations of type=boundary to tag the
borders properly.<br>
<br>
there's always only ONE way to define a border. always use the highest
appropriate admin_level, ie. if a district border is a state border as
well, tag the way as a state border. no names or anything else here,
just boundary=administratve and admin_level.<br>
<br>
then intoduce several type=boundary relations, one for each
administrative unit. for instance: if a district border is a state
border as well but not a national border, then you'll need 4 relations:
2 for the districts and another two for the states. the ONE border way
is a member of all 4 relations.<br>
<br>
hope i meda myself clear, if not see here: <a moz-do-not-send="true"
