Dissertation submitted in partial fulfilment of the requirements for the Degree of Master of Science in Geospatial TechnologiesSince its rst appearance the Internet of Things has been subject to constant evolution,
development and change. Now it has stepped out of its infancy with billions of
devices embedded in the world wide web. However, IoT providers mostly de ne their
own data formats and protocols and there is still a lack of a common standard that
connects these devices in an interoperable manner. There are several organisations
dedicated to developing common standards for IoT devices and research is focusing
on de ning an e ective standard to be used by embedded devices. Unsurprisingly,
IoT has also found its way into the spatial web and into environmental monitoring
and sensing platforms connected over the web by wireless sensor networks are now a
common way to monitor natural phenomena. This study compares three open Web
Standards in the use case of SEnviro for Agriculture, a full stack IoT for monitoring
vineyards. The interoperability potential of the OGC's Sensor Observation Service
and SensorThings API are evaluated by integrating Web Standard implementations
for each standard and contrasting their qualitative and quantitative traits.
In a further step the Mozilla Corporation's Web Thing API was implemented and
evaluated in an environmental monitoring and Smart Farming context. The results
of the study show that the SensorThings API proves to be the most adequate Web
Standard for SEnviro and IoT applications for environmental monitoring and Smart
Farming in terms of interoperability. It outperforms the contesting Web Standards
in terms of
exibility and scalability, which strongly impacts on developer and user
experience
