[OSM-dev] New planetosm-to-db.pl with bounding box support

[Nick Whitelegg]

I've just added an altered and rather quick-and-dirty version of 
planetosm-to-db.pl which allows the user to specify a bounding box to 
retrieve. 

It appears to "do the job" and took about two hours or so to do all the UK 
between 50N and 58N and west of 1W. However the code needs tidying up/making 
more robust; I've committed it to subversion in case someone else gets round 
to this before I do. Note also that SQL/XML errors are just ignored for the 
moment (this has some advantages e.g. the script doesn't stop if duplicate 
ways are added, which might be the case if you run the script several times 
as a batch job with different bounding boxes)

Example command for the 7W,49N,2E,59N bounding box:

./planetosm-to-db-bbox.pl -bbox -7,49,2,59 planet.osm

There is one real bug. When dealing with ways, the second segment in the way 
is not added. An SQL error relating to duplicate segments is raised when the 
second segment is added. Looking at the code I can't see an obvious reason 
for this but will try and debug.
