<p>The ESA-NASA multi-Mission Algorithm and Analysis Platform (MAAP) is dedicated to the BIOMASS [1], NISAR [2] and GEDI [3] missions. This analysis platform will be a virtual open and collaborative environment. The main goal is to bring together data centres (Earth Observation and non-Earth Observation data), computing resources and hosted processing in order to better address the needs of scientists and federate the scientific community.</p><p>The MAAP will provide functions to access data and metadata from different sources such as Earth observation satellites data from science missions; visualisation functions to display the results of the system processing (trends, graphs, maps ...) and results of statistic and analysis tools; collaborative functions to share data, algorithms, ideas between the MAAP users; processing functions including development environments and an orchestration system allowing to create and run processing chains from official algorithms.</p><p>Currently, the MAAP is in its pilot phase. The architecture for the MAAP pilot foresees two independent elements, one developed by ESA, one developed by NASA, unified by a common user entry point. Both elements will be deployed on Cloud infrastructures. Interoperability between the elements is envisaged for data discovery, data access and identity and access management.</p><p>The ESA element architecture is based on technical solutions including: Microservices, Docker images, Kubernetes; Cloud-based virtual development environments (such as Jupyter or Eclipse CHE) for the MAAP algorithm developers; a framework to create, run and monitor chains of algorithms containerised as docker images. Interoperability between both ESA and NASA elements will be based on CMR (NASA Common Metadata Repository), services bases on OGC standards (such as WMS/WMTS, WCS and WPS) and secured with the OAUTH2 protocol.</p><p>This presentation focuses on the pilot platform and how interoperability between the NASA and ESA elements will be achieved. It also gives insight into the architecture of the ESA element and the technical implementation of this virtual environment. Finally, it will present the very first achievements and return of experience of the pilot platform.</p><p> </p><p><strong>REFERENCES</strong></p><p>[1] T. Le Toan, S. Quegan, M. Davidson, H.

In recent years, Earth observation (EO) satellites have generated big amounts of geospatial data that are freely available for society and researchers. This scenario brings challenges for traditional spatial data infrastructures (SDI) to properly store, process, disseminate and analyze these big data sets. To meet these demands, novel technologies have been proposed and developed, based on cloud computing and distributed systems, such as array database systems, MapReduce systems and web services to access and process big Earth observation data. Currently, these technologies have been integrated into cutting edge platforms in order to support a new generation of SDI for big Earth observation data. This paper presents an overview of seven platforms for big Earth observation data management and analysis—Google Earth Engine (GEE), Sentinel Hub, Open Data Cube (ODC), System for Earth Observation Data Access, Processing and Analysis for Land Monitoring (SEPAL), openEO, JEODPP, and pipsCloud. We also provide a comparison of these platforms according to criteria that represent capabilities of the EO community interest.

The COVID-19 pandemic has infected almost 73 million people and is responsible for over 1.63 million fatalities worldwide since early December 2019, when it was first reported in Wuhan, China. In the early stages of the pandemic, social distancing measures, such as lockdown restrictions, were applied in a non-uniform way across the world to reduce the spread of the virus. While such restrictions contributed to flattening the curve in places like Italy, Germany, and South Korea, it plunged the economy in the United States to a level of recession not seen since WWII, while also improving air quality due to the reduced mobility. Using daily Earth observation data (Day/Night Band (DNB) from the National Oceanic and Atmospheric Administration Suomi-NPP and NO2 measurements from the TROPOspheric Monitoring Instrument TROPOMI) along with monthly averaged cell phone derived mobility data, we examined the economic and environmental impacts of lockdowns in Los Angeles, California; Chicago, Illinois; Washington DC from February to April 2020—encompassing the most profound shutdown measures taken in the U.S. The preliminary analysis revealed that the reduction in mobility involved two major observable impacts: (i) improved air quality (a reduction in NO2 and PM2.5 concentration), but (ii) reduced economic activity (a decrease in energy consumption as measured by the radiance from the DNB data) that impacted on gross domestic product, poverty levels, and the unemployment rate. With the continuing rise of COVID-19 cases and declining economic conditions, such knowledge can be combined with unemployment and demographic data to develop policies and strategies for the safe reopening of the economy while preserving our environment and protecting vulnerable populations susceptible to COVID-19 infection.

Urban forests contribute significantly to the ecological integrity of urban areas and the quality of life of urban dwellers through air quality control, energy conservation, improving urban hydrology, and regulation of land surface temperatures (LST). However, urban forests are under threat due to human activities, natural calamities, and bioinvasion continually decimating forest cover. Few studies have used fine-scaled Earth observation data to understand the dynamics of tree cover loss in urban forests and the sustainability of such forests in the face of increasing urban population. The aim of this work was to quantify the spatial and temporal changes in urban forest characteristics and to assess the potential drivers of such changes. We used data on tree cover, normalized difference vegetation index (NDVI), and land cover change to quantify tree cover loss and changes in vegetation health in urban forests within the Nairobi metropolitan area in Kenya. We also used land cover data to visualize the potential link between tree cover loss and changes in land use characteristics. From approximately 6600 hectares (ha) of forest land, 720 ha have been lost between 2000 and 2019, representing about 11% loss in 20 years. In six of the urban forests, the trend of loss was positive, indicating a continuing disturbance of urban forests around Nairobi. Conversely, there was a negative trend in the annual mean NDVI values for each of the forests, indicating a potential deterioration of the vegetation health in the forests. A preliminary, visual inspection of high-resolution imagery in sample areas of tree cover loss showed that the main drivers of loss are the conversion of forest lands to residential areas and farmlands, implementation of big infrastructure projects that pass through the forests, and extraction of timber and other resources to support urban developments. The outcome of this study reveals the value of Earth observation data in monitoring urban forest resources.
