  As the number of computing devices embedded into engineered systems continues
to rise, there is a widening gap between the needs of the user to control
aggregates of devices and the complex technology of individual devices. Spatial
computing attempts to bridge this gap for systems with local communication by
exploiting the connection between physical locality and device connectivity. A
large number of spatial computing domain specific languages (DSLs) have emerged
across diverse domains, from biology and reconfigurable computing, to sensor
networks and agent-based systems. In this chapter, we develop a framework for
analyzing and comparing spatial computing DSLs, survey the current state of the
art, and provide a roadmap for future spatial computing DSL investigation.
