Hello, Here's a quick update on my GSoC project so far:
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. Second, I am working on actually producing data tiles. Currently, I am using a city-sized subset (the extract of San Francisco from http://metro.teczno.com) which is processed with osm2pgsql. I have set up a simple web service which produces tiles on demand and a Leaflet canvas layer which I am using to inspect the results of producing the tiles, so I can see renderings of the tiles in context. 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. 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: https://github.com/mdaines/augment-osc Thanks to everyone who has offered suggestions and advice! -- Michael _______________________________________________ dev mailing list dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/dev
