So could you specify a better projection that would be equidistant? The

Would 4326 be equidistant?
FWIW, this is what I'm using on my cycle map:
ST_length_spheroid(transform(way,4326),'SPHEROID[WGS
Thank you for your thoughtful suggestions. I'm a n00b, so I'm not sure if I
have to setup my own instance of the database to run this query or, if not,
where I should go next. Any additional suggestions or direction would be

Hi,
I've been given a project to look at dead-end streets, specifically short
ones under the assumption that these may represent incomplete development.
How can I search OSM for:
- the shortest streets in my city/country/planet
- streets which are long but have many short, discontinuous segments

something like this?
select osm_id, st_length(way) as length from planet_osm_roads order by
length asc limit 10
31970890;0.00747434498740587
32782134;0.01093132

Something, but not exactly that. ST_Length(way) is in projected meters,
which varies with latitude.

That may be too simplistic assumption, recent developments I've been
mapping out basically have
