Over the last decade, the Internet of Things (IoT) paradigm has been widely used in a wide variety of scenarios, including smart cities, health, transportation, industry, and agriculture, among others. A study from CompTIA, Inc., points out that the number of devices connected to the Internet will reach 50.1 billion by 2020. By connecting billions of devices to the Internet, IoT has demonstrated its potential to revolutionize society and has attracted significant attention and investment from industry and academia.

IoT devices can observe and act over the environment; large networks of IoT devices are being created and deployed in many application domains, most of which are also relevant for Digital Earth applications. This massive deployment of IoT Devices is generating the so-called electronic skin of the Earth, a layer of interrelated IoT devices capable of monitoring, sensing, knowing and acting accordingly on the environment. New systems, techniques and methods are therefore needed to manage this wealth of devices and analyze the continuous pulse of spatio-temporal data that are ever-increasingly generated, especially in relation to Digital Earth applications.

Our colleagues Carlos Granell and Sergi Trilles are guest editors of a Special issue about Internet of Things as an enabler of Digital Earth that will be published Autumn 2019.

We seek research submissions that include (but are not limited to) the following topics:

• Conceptual/Technological frameworks to manage and analyze IoT devices
• Development of IoT devices
• Spatial decision support system (SDSS) based on IoT devices
• Novel methods for spatial acquisition on IoT devices
• Geospatial IoT standards deployments
• IoT, Big Data and Analytics: Challenges and new trends
• IoT applications in cities, rural areas, disaster manager, health and agriculture

Deadline for paper submission is May 1, 2019
