I just wanted to let you know that the CommonMap initiative is still
alive, as am I.
To recap, CommonMap will be a collaboration and repository of
liberally-licensed geodata (without share-alike) - accessible though an
OpenStreetMap-style interface. We will accept Creative Commons
Attribution, CC0 and public domain geodata contributions, depending on
your jurisdiction. We expect it will find fresh acceptance in the "Gov
2.0" movement, since it allows governments to redistribute contributions
from the community. We also are quite happy to accept OpenStreetMap
contributors who find themselves dissatisfied with its default licence.
We want to focus on a particular country at first, which is Canada. Why?
* It has quite a comprehensive open data catalogue;
* It appears to have a compatible licence;
* It also has a rigorous "foreign key" model, which bodes well for
roundtripping back to government;
* It's the home of Refractions Research, the custodian of PostGIS
which is a good friend of mine;
* Finally, it helps that Sam Vekemans is our enthusiastic man on
the ground over there.
We want to get as much of Natural Resources Canada's GeoBase and Canvec
publications into the CommonMap database as we can, and use Canada as a
showcase country for what CommonMap can uniquely do.
The "proof of concept" API instance is currently at
It is hosting an overlay of:
* Natural Earth Data;
* Some sample Geobase National Road Network, National Hydro
Network and Land Cover datasets.
(Hint: look up Victoria, British Columbia for an example of all 3
Next comes the challenge of ramping up to a public launch. The core of
CommonMap is a web-facing API and its "one true" database, a download
site for XML full copies of that database, and a map tile server with
its optimised database. To run this at public scale will demand about
8-10 CPU cores and associated storage, or about US $10,000 per year.
Let's face it, we will require a higher rate of donations to do this. If
you believe in the idea of CommonMap, a good way to show your support is
to donate to CommonMap Inc. (CommonMap Inc is the non profit body that
operates the CommonMap internet resources.)
Potential donors, please head this way:
Even if you can't spare the cash, perhaps you can spare your skills or
tools, whether they be in geodesy, obtaining or converting geodata
imports, running up database or tile servers, or developing
applications? Let us know.
Please feel free to forward this news to whoever you wish.
