Un Enfoque para la Integración de Dispositivos IoT en el Desarrollo de SIG en la Nube

Cloud computing and Internet of Things (IoT) as technological support to the construction of Geographic Information Systems (GIS) is changing the way these systems are developed and employed. The technological infrastructure provided by cloud providers and used as deployment platform enables GIS to take advantage of its storage and processing capabilities, whereas using IoT devices automate the data collection process. However, current implementations of GIS, whose services are used on cloud environments and interact with IoT devices, are realized in an ad hoc manner, without providing solutions that ease their design and implementation. This work proposes a development approach, which from models that describe at a high abstraction level both the system architecture as well as the interaction among its services and IoT devices, guides the implementation and deployment on cloud environments activities. The feasibility of this approach has been illustrated by the design and implementation of a GIS application that analyzes spatial data collected by air quality sensors, with services deployed in the Google Cloud platform.
