Increased support for Sensor Web standards
With the advent of low-cost, low-bandwidth and low-power IoT sensors, new requirements for data handling have arisen. The OGC SensorThings API (STA) was developed to accompany those new requirements and integrate those new sensors into the Sensor Web. It “[…] provides an open, geospatial-enabled and unified way to interconnect the Internet of Things (IoT) devices, data, and applications over the Web” (Preface to the OGC SensorThings API Part 1: Sensing). The main focus of this development is to find a solution for the heavy restraints on available resources. The STA therefore defines a lightweight REST-API, as well as an MQTT binding for easy retrieval and storage of Sensor Data with a minimal overhead. The “SensorThings API Part 1: Sensing” was officially adopted as an OGC Standard in late 2016, the “SensorThings API Part 2: Tasking” is currently under development.
