Ubiquitous and context-aware sensors are increasing in number and aim at providing comfort and better life quality. They are spatially distributed and their computation capacity is still under-exploited. Spatial Edge Service are a new generation of services exploiting IoT and spatially distributed data. They result from collective and decentralised interactions of multiple computing entities. They rely on a logic and chemical-based coordination model. Spatial edge services provide innovation capabilities for the software industry, connected objects manufacturers and edge computing industry. This paper provides and overview of Spatial Edge Services, their underlying coordination model, a set of development tools, a series of case studies scenarios and future visions.
