Design

This new API is based on a PostgreSQL backend that massively uses stored procedures and a mod_python script.

Server API

Requesting the update of a series of tiles

http://www.openstreetmap.fr/tah.py/request_tile_update?x=1&y=2&z=12&p=11&id=user

in which

• x is the tile coordinate in the longitude axis
• y is the tile coordinate in the latitude axis
• z is the first zoom level that should be drawn (valid values are 0, 3, 6, 9 and 12)
• p is the priority
• id is a string that helps finding who requested what

the response to this request is either

OK

or an appropriate HTTP error

Requesting a tile set to work on

http://www.openstreetmap.fr/tah.py/grab_job?user=sxpert&password=testpassword&version=test

the typical response should be:

OK|4|<job id>|<x>|<y>|<z>|HAVE FUN

or some error like

XX|4|||||INVALID SOFTWARE VERSION
XX|4|||||CLIENT VERSION DEPRECATED
XX|4|||||NOTHING TO DO

Requesting an upload ticket for a job

http://www.openstreetmap.fr/tah.py/get_upload_ticket?user=sxpert&password=testpassword&job_id=2
