The Astral Protocol provides the bindings between the spatial data domain and the Web3 universe. We intend to make no assumptions about the needs or use cases of developers building on Astral; instead, our effort is directed at creating a simple, versatile way of connecting both raster data and vector geometries, and relevant metadata, to smart contract and dApp front end interfaces. We believe that these spatial data primitives, along with the means to integrate them into smart contracts, will provide the soil from which the Web3 spatial ecosystem will sprout.
