Mapping Aggregation Platform (MAP) is a conceptual decentralized protocol that enables the gathering and sharing of geospatial data through the blockchain. To create this map, the community contributes mapping information that is used to build a digital representation of the world. To enrich the map, the community embeds location-specific information on the world’s digital representation. With this digital representation of the world, anyone can build high-quality and accurate location-based applications and services on top of the MAP blockchain. The MAP blockchain would ultimately allow for an interoperable “write once, use everywhere” model.
