OpenStreetMap Blockchain Protocol

OpenStreetMap.org (OSM) is a community driven mapping platform that offers completely free & open source mapping data, some would call it the WikiPedia for maps. Anyone is allowed to edit, download & use OpenStreetMap completely for free. Unfortunately, to build DApps using such public mapping database would require an immense amount of work to simply load the data and to keep it updated.

EOS Nation is proposing to develope a protocol which would allow DApps developpers to interact with the OpenStreetMap database directly on the EOS blockchain. In addition an OpenStreetMap monitoring system would be deployed on the EOS blockchain which would continously sync the live OpenStreetMap data to the blockchain.

OSM Statistics Tiles

The goal of this dataset/project would be to generate geospatial statistics based on OpenStreetMap data and stored as JSON and PBF formats. These pre-computed tiles would enable data scientists to perform complex geospatial analysis at a country wide scale with minimal CPU processing.

Geospatial statitics

There could be thousands of different geospatial statitics that could be generated from a simple OSM dataset within a given BBox, here's a list of the most useful geospatial statitic that would be defined:

• highway=* (path, residential, secondary, etc...)
