NODES will mobilize the tools of citizen and data science combined with Earth observations to monitor, analyze, and foster progress towards the UN Sustainable Development Goals (SDGs).

To realize this vision, NODES will exploit novel data ecosystems in which several actors interact via infrastructure, analytics, and applications to produce, analyze, exchange, and consume data.

Three main cross-fertilizing pillars characterize the research focus of NODES: 

  • Advancing the field of citizen science: NODES will remain at the forefront of citizen science from conceptual advancements to innovations in citizen science practice, including the development of new means to acquire, analyze, and openly share citizen science data, as well as how citizen science can contribute to the SDGs and sustainability.
  • Enriching Earth observation: NODES will utilize new types of Earth observation technology (e.g., high-resolution imagery, drones, and the Internet of things (IoT)) and develop applications that focus on the interplay between Earth observation and citizen science using Geo-Wiki tools, various forms of remote sensing, and on-site observation.
  • Exploiting the digital revolution: NODES will harness the opportunities arising from the digital revolution by exploiting advancements in computing capabilities, data science (e.g., machine and deep learning), environmental informatics, and the geospatial sciences, among others, to enhance integrated systems science research and generate new and innovative data sets for further insights.

From farm to space and back: adapting Austrian agriculture to climate change

Juan Carlos Laso Bayas and colleagues reflect on the outcomes of the SATFARM Services project, which set out to create models that demonstrate the potential of satellite data to track climate-smart agricultural practices and visualize indicators to track their success in a prototype web platform for Austrian farmers.

Building trust in science for a sustainable future

Options Magazine, Winter 2022: Science-informed policy is crucial to solving the interconnected and complex global to local problems society faces today. There is, however, one essential element that is critical to the success of such an ambitious endeavor: trust in the scientific information provided.
