Hi,
I have a little Python application that populates a posgresql database using
osm2pgsql, renders a map with mapnik and extracts information from the
database to highlight points of interest.
I am having a bit of trouble with working out what units the coordinates of
nodes are in in the postgresq
I think I have found the problem - I was using planet_osm_nodes lat and lon
fields. If I use the planet_osm_point way field, and extract the
coordinates using ST_X() and ST_Y() all of the numbers match up.
You can see the factor of 100 difference if you do:
select id,lat,lon,astext(way) fro

The num_changes data is weird.

Thanks Jon,
I thought it might be an efficiency thing, but wasn't sure when we are using
the postgis extensions anyway. I didn't get that far through the osm2pgsql
source code to spot it!

Here's an interesting pair of nodes:
http://www.openstreetmap.org/api/0.6/node/558001392/2
http://www.openstreetmap.org/api/0.6/node/554816398/2
There's a version 2, but no version 1.
