1. 1. Geospatial data and knowledge on the Web : Knowledge-based geospatial data integration and visualisation with Semantic Web technologies

   Författare :Weiming Huang; Institutionen för naturgeografi och ekosystemvetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geospatial data integration; data visualisation; Semantic Web; Linked Data; ontology;

   Sammanfattning : Geospatial information is indispensable for various types of spatially informed analysis and decision-making, such as traffic analyses, and natural resource management. In addition, geospatial information is one of the most powerful information integrators to bridge diverse sources of information. LÄS MER

5. 4. The use of global data to uncover how humans shape flood and drought risk

   Författare :Sara Lindersson; Giuliano Di Baldassarre; Johanna Mård; Luigia Brandimarte; Brett Sanders; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; natural hazards; hydrological disasters; environmental geography; global geospatial data; international databases; disaster losses; disaster consequences; water management; dams and reservoirs; floodplains; hydrological drought; social vulnerability; economic inequality; Anthropocene; Geovetenskap med inriktning mot miljöanalys; Earth Science with specialization in Environmental Analysis;

   Sammanfattning : The human consequences of flood and drought disasters are widespread and detrimental. Large-scale studies, drawing on global geodata products and international databases, can systematically examine how anthropogenic megatrends shape disaster risk and test the generalisability of findings from other scientific methodologies.

7. 5. Multi-Modal Deep Learning with Sentinel-1 and Sentinel-2 Data for Urban Mapping and Change Detection

   Författare :Sebastian Hafner; Yifang Ban; Paolo Gamba; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Geoinformatics; Geoinformatik;

   Sammanfattning : Driven by the rapid growth in population, urbanization is progressing at an unprecedented rate in many places around the world. Earth observation has become an invaluable tool to monitor urbanization on a global scale by either mapping the extent of cities or detecting newly constructed urban areas within and around cities.
