Pressures on natural resources are increasing and a number of challenges need to be overcome meet the needs growing population in period environmental variability. Some these issues can monitored using remotely sensed Earth Observations (EO) data that increasingly available from freely openly accessible repositories. However, full information potential EO has not been yet realized. They remain still underutilized mainly because their complexity, volume, lack efficient processing...
The concept of Digital Earth (DE) was formalized by Al Gore in 1998. At that time the technologies needed for its implementation were an embryonic stage and quite visionary. Since then digital have progressed significantly their speed pervasiveness generated are still causing transformation our society. This creates new opportunities challenges realization DE. ‘What is DE today?’, could be future?’, to make a reality?’. To answer these questions it necessary examine considering all...
Land degradation is a critical issue globally requiring immediate actions for protecting biodiversity and associated services provided by ecosystems that are supporting human quality of life. The latest Intergovernmental Science-Policy Platform on Biodiversity Ecosystem Services Landmark Assessment Report highlighted activities considerably degrading land threating the well-being approximately 3.2 billion people. In order to reduce ideally reverse this prevailing situation, national...
Data concerning the occurrence of emerging biological contaminants such as antibiotic resistance genes (ARGs) and fecal indicator bacteria (FIB) in aquatic environments Sub-Saharan African countries is limited. On other hand, remains a worldwide problem which may pose serious potential risks to human animal health. Consequently, there growing number reports prevalence dissemination these into various environmental compartments. Sediments provide opportunity reconstruct pollution history...
Avoiding, reducing, and reversing land degradation restoring degraded is an urgent priority to protect the biodiversity ecosystem services that are vital life on Earth. To halt reverse current trends in degradation, there immediate need enhance national capacities undertake quantitative assessments mapping of their lands, as required by Sustainable Development Goals (SDGs), particular, SDG indicator 15.3.1 ("proportion over total area"). Earth Observations (EO) can play important role both...
Since the opening of Earth Observation (EO) archives (USGS/NASA Landsat and EC/ESA Sentinels), large collections EO data are freely available, offering scientists new possibilities to better understand quantify environmental changes. Fully exploiting these satellite will require approaches for their acquisition, management, distribution, analysis. Given rapid changes emergence big data, innovative solutions needed support policy frameworks related actions toward sustainable development. Here...
Abstract Standard and easily accessible cross-thematic spatial databases are key resources in ecological research. In Switzerland, as many other countries, available data scattered across computer servers of research institutions rarely provided standard formats (e.g., different extents or projections systems, inconsistent naming conventions). Consequently, their joint use can require heavy management geomatic operations. Here, we introduce SWECO25 , a Swiss-wide raster database at 25-meter...
Abstract. With growing world population and concentration in urban coastal areas, the exposure to natural hazards is increasing results higher risk of human economic losses. Improving identification assets potentially exposed essential reduce consequences such events. Disaster a function hazard, vulnerability. Modelling at global level requires accessing processing large number data, from numerous collaborating centres. These data need be easily updated, there for centralizing access this...
This study aims at assessing the feasibility of automatically producing analysis-ready radiometrically terrain-corrected (RTC) Synthetic Aperture Radar (SAR) gamma nought backscatter data for ingestion into a cube use in large spatio-temporal environment. As such, this investigates analysis readiness different openly available digital elevation models (DEMs) and capability software solutions SNAP GAMMA terms overall usability as well quality. To achieve this, builds on Python library pyroSAR...
Earth Observation Data Cubes (EODC) have emerged as a promising solution to efficiently and effectively handle Big (EO) generated by satellites made freely openly available from different data repositories. The aim of this Special Issue, “Earth Cube”, in Data, is present the latest advances EODC development implementation, including innovative approaches for exploitation satellite EO using multi-dimensional (e.g., spatial, temporal, spectral) approaches. This Issue contains 14 articles...
In 2015, it was adopted the 2030 Agenda for Sustainable Development to end poverty, protect planet and ensure that all people enjoy peace prosperity. The year after, 17 Goals (SDGs) officially came into force. GEO (Group on Earth Observation) declared support implementation of SDGs. Global Observation System Systems (GEOSS) required a change paradigm, moving from data-centric approach more knowledge-driven one. To this end, System-of-Systems (SoS) framework may refer well-known...
To tackle Big Data challenges such as Volume, Variety, and Velocity, the Earth Observations Cube (EODC) concept has emerged a solution for lowering barriers offering new possibilities to harness information power of satellite EO data. However, installing, configuring, managing an EODC instance is still difficult requiring specific knowledge capabilities. Consequently, facilitating automating generation provision given user's requirements can be beneficial. In response this issue, paper...
Cities are recognised as key enablers for the world’s sustainable future. Urban sprawl and inefficient use of land important issues significantly impacting provision open green spaces. The United Nations Sustainable Development Goal (SDG) indicator 11.7.1 aims at globally monitoring amount that is dedicated by cities public space. In Europe, “Share urban population without areas in their neighbourhood” supposed to correspond SDG11.7.1 but currently on-hold due methodological lack data....
