I have been documenting the data tile format from the Kothic project (including
the details of how map features are cropped, etc.) which is at present what the
data tile format I am working on will be based on. I am also working on
describing other schemes for cropping OSM data, and other JSON representations
of OSM data.
Is this documentation-draft published somewhere? Would really like to
take a view into it.
I will post this work (the documentation and the tile production script and web
testbed) on the wiki and in a GitHub repository in the coming week.
Ahh, forget my question from above ;)
Finally, I have been working on a script for producing augmented diffs (as
suggested a little while ago on the list by my mentor) by querying the Overpass
API, meant to make keeping a replica of the planet up to date with minute diffs
more tenable in the face of data processing speed and the possibility of
missing data and broken geometry. An initial version is here:
Isn't this a totaly unreleated project? Although its more interesting
then a Tiled-Data-Service to me :) Despite that I'd strongly vote for
NOT using Pverpass-API, because of multiple problems that could arise
from this dependency:
- Overpass API is a important tool for Individuums to get specific
data they're interested in. It's no good idea to occupy that api
with another service
- It's no good idea to provide a service that depends on another
service that is not maintained by you.
- Your tool yould be a lot faster when you base it on a specialized
database and not on a generic api
I think it would be far better for an diff-augmentation-server to hold
its own specialized database, optimized for the single job of augmenting
diffs. (remember: preprocessing is everything in the osm universe)
