“…Machine-learning methods have been applied across a range of science and engineering applications for more than 2 decades. A number of recent examples have targeted the (retrospective) prediction or retrieval of hydrological states and fluxes from single-and multi-satellite sources, including the estimation of typhoon rainfall over the ocean (Chen et al, 2011), the retrieval of surface soil moisture (Rodríguez-Fernández et al, 2016) and water vapour content (Aires et al, 2001), the estimation of river runoff (Rasouli et al, 2012;Deo andŞahin, 2016), the analysis of global hydro-climatic controls on vegetation (Papagiannopoulou et al, 2017), the training of high-resolution sensors for retrieval of NDVI (Houborg and McCabe, 2016), and the derivation of continental water and carbon fluxes using decision trees (Jung et al, 2009). Still, the application of these techniques to dynamically monitor hydrological events and processes using remote sensing remains an emerging field, with relatively limited existing applications.…”

“…For instance, Landsat-8 (which is around the size of a large car), had an estimated cost of USD 855 million to build and launch, and therefore producing multiple versions (not including associated launch costs) is not a realistic proposition. The 2014-2020 budget for the European Copernicus Earth observation program, which includes the Sentinel missions, is estimated at approximately EUR 4.3 billion, but does not include multi-satellite constellations beyond the Sentinel-2 pair (Denis et al, 2016). Here the key limitation in the replication of multiple sensing platforms relates to the satellites size and the associated price tag.…”

Abstract. In just the past 5 years, the field of Earth observation has progressed beyond the offerings of conventional space-agency-based platforms to include a plethora of sensing opportunities afforded by CubeSats, unmanned aerial vehicles (UAVs), and smartphone technologies that are being embraced by both for-profit companies and individual researchers. Over the previous decades, space agency efforts have brought forth well-known and immensely useful satellites such as the Landsat series and the Gravity Research and Climate Experiment (GRACE) system, with costs typically of the order of 1 billion dollars per satellite and with concept-to-launch timelines of the order of 2 decades (for new missions). More recently, the proliferation of smartphones has helped to miniaturize sensors and energy requirements, facilitating advances in the use of CubeSats that can be launched by the dozens, while providing ultra-high (3-5 m) resolution sensing of the Earth on a daily basis. Startup companies that did not exist a decade ago now operate more satellites in orbit than any space agency, and at costs that are a mere fraction of traditional satellite missions.With these advances come new space-borne measurements, such as real-time high-definition video for tracking air pollution, storm-cell development, flood propagation, precipitation monitoring, or even for constructing digital surfaces using structure-from-motion techniques. Closer to the surface, measurements from small unmanned drones and tethered balloons have mapped snow depths, floods, and estimated evaporation at sub-metre resolutions, pushing back on spatio-temporal constraints and delivering new process insights. At ground level, precipitation has been measured using signal attenuation between antennae mounted on cell phone towers, while the proliferation of mobile devices has enabled citizen scientists to catalogue photos of environmental conditions, estimate daily average temperatures from battery state, and sense other hydrologically important variables such as channel depths using commercially available wireless devices. Global internet access is being pursued via highaltitude balloons, solar planes, and hundreds of planned satellite launches, providing a means to exploit the "internet of things" as an entirely new measurement domain. Such globalPublished by Copernicus Publications on behalf of the European Geosciences Union. The future of Earth observation in hydrology access will enable real-time collection of data from billions of smartphones or from remote research platforms. This future will produce petabytes of data that can only be accessed via cloud storage and will require new analytical approaches to interpret. The extent to which today's hydrologic models can usefully ingest such massive data volumes is unclear. Nor is it clear whether this deluge of data will be usefully exploited, either because the measurements are superfluous, inconsistent, not accurate enough, or simply because we lack the capacity to process and analyse them.

“…Because of the ever-increasing number of satellites, products and number of customers, the system should support custom-made business workflows and execution capabilities. As Earth observation satellites play a significant role in supporting the action of quick responders in case of emergency events (Denis, Boissezon, and Hosford 2016), more and more both professional and non-professional data application users need instant or near real-time services about satellite imaging and "area of interest" imagery. Recently, mobile devices have become very popular, as they provide convenient and shortcut methods to recognize and understand geospatial data products.…”

a 21st century aerospace technology co., ltd., Beijing, china; b 21st century aerospace technology (asia) pte. ltd., singapore ABSTRACTWith the increase of different sensors, applications and customers, the demand from data providers and users is for a new geospatial data service model, which supports low cost, high dexterity, and which would provide a comprehensive service. Based on such requirements and demands, the 21AT TripleSat constellation terminal and data delivery and management system has been developed by a Beijing based high-tech enterprise, Twenty First Century Aerospace Technology Co., Ltd. (21AT). The company is the first commercial Earth observation satellite operator and service provider in China. This new geospatial data service model allows the user to directly access multi-source satellite data, manage the data order, and carry out automatic massive data production and delivery. The solution also implements safe and hierarchical user management, statistical data analysis, and automatic information reports. In addition, a mobile application is also available for users to easily access system functions. This new geospatial solution has already been successfully applied and installed in many customer sites in China, and is now available globally for international clients interested in fast geospatial solutions. It enables the success of customers' operational services. Besides providing TripleSat Constellation images, the multi-source data access system also allows the users to access other satellite data sources, based on customized agreement. This paper describes and discusses this new geospatial data service model.
