Peer to peer cartography

Peermaps is a p2p, offline-friendly way to distribute, view, and embed map data. Instead of fetching data from a centralized tile provider, you fetch data from other peers on the network. Right now we have all of OpenStreetMap processed into a 100GB archive in our p2p spatial database and rendering formats and seeded to hyperdrive and ipfs. This data is hooked up to a proof-of-concept web map viewer.

For this grant, we will build on our proof-of-concept to release a user-oriented map viewer as a web application with search functionality on along with a developer-oriented tool to embed web maps in an iframe. In addition to (p2p) web development, this project will involve research on peer queries for offline and online location-based search, optimizations to the spatial database and p2p layer, webgl graphics improvements in addition to web development in order to produce a usable p2p mapping alternative.
