Signals and Telecommunication Journal Tomaz Rodi, Ana Urbas 8 1 2019 http://www.dline.info/stj/fulltext/v8n1/stjv8n1_4.pdf Satellite technologies have a huge potential to help design more sustainable cities. Combination of Earth observation imagery and crowdsourced data enables a creation of a series of data analyses and applications to support smart urban planning, climate change mitigation and to enhance the quality of life in smart cities and communities. SPACE-SI with its micro satellite for multispectral Earth observation, ground station, multidisciplinary laboratory, satellite data processing chain and a distribution system based on web and mobile applications ensure the whole chain from the space technologies to the end user friendly data and derived information. Timely geolocated information is crucial for well organized smart cities and communities. Our expertise is near real- time processing of space-borne data and the extraction of the needed information from this ever-growing data source.
