Serverless Data Storage for Scalable Geospatial Applications in the Cloud

Holderness, Tomas; Varley, Mark

This paper presents a web service that combines recent developments in geospatial indexing with serverless cloud storage to provide a scalable architecture for querying geospatial data. The service uses a key-value database, indexed using the H3 spatial index as a cache for multiple geographical data-sets. In instances where cached data is unavailable, secondary raster and vector services provisioned using Cloud Optimised GeoTiffs and a scaleable PostGIS database can be queried with point or polygon geometries. The service is used to provide Addresscloud’s Intelligence API, which is a global service that provides property-scale geographic risk assessments to insurance underwriters.
