It would be ideal if the Wiki could be relied upon as a guide to
everything in OSM so that if you want to know how is X usually done in
OSM you can turn to the Wiki and find

Hi - N00b question here:
What's the role of the wiki as a source of information in the OSM community?
It's a mixed bag, some of the information is very good and of high
quality and some is outdated, and some is of low quality.
i'm looking at a need to do some analysis estimation based on road nets
extracted from OSM; the goal is to be able to estimate things like time to
complete ground surveys (e.g., TIGER review and collection of hydrant
locations.)
are there any libraries or tools kicking around that folks might

Richard,
If the data you're using is in PostGIS ST_Length will give you the length
of all the ways of interest within a bounding box, and, if you reproject to
EPSG:900913 before calling the function you'll get the results in meters.
select ST_length( ST_Transform( linestring, 900913 ) ), id,
It's worth noting that the results will be in Mercator meters, not meters.
I have OSM loaded into a pgsnapshot db and can run queries on request.
Something else is that tags-'highway' in ( 'motorway', 'primary',
'secondary' ) will NOT use indexes on tags.
tags @ hstore('highway',
Interesting, I have been looking for a way to speed up those types of
queries for a while, thanks!
Do you have metrics on this?

These are the sorts of queries that jxapi does all the time.
hstore's @ and ? operators use index, others don't.
As far as metrics... an xapi query like
[highway=*][ref|name=*][bbox=a,b,c,d] on jxapi was taking ~5-10 hours when
it was using exists(tags, 'highway') (which doesn't use the index on
I'll just say that, whether bug or feature, this message perfectly
encapsulates why I am unwilling to spend my time working on OSM. I don't
want to waste my time, and by not having a good place to learn what to do,
I have to do a whole lot of work to figure out whether the additions I'm making

No place to learn what to do? The wiki may be overwhelming, sometimes
outdated and incorrect, or even a vehicle for personal opinions on
tagging and whatnot, but there are definitely resources to help you
get started. All OSM editors have useful presets for common features,
you can't really go
Kathleen,
Yes, the Welcome WG does need a boost after Richard's (cc) initial
great work on the proposal and initial meeting. I wanted to wait until
the semester is over so that my teaching obligations would not keep
interfering, but I guess we're almost there, so I am willing to
organize a next
*Some of these resources may require a

**or interconnected as they should be,* but you have to realize that
OpenStreetMap is eternally a work in progress, run entirely by
volunteers who are working really hard to keep up
For those who already looked at the doodle: I changed the times just
now as I realized the proposed times would be in the middle of the
night for Europe.
