UN-SPIDER Knowledge Portal
Help Shape the Future of the UN-SPIDER Knowledge Portal
The UN-SPIDER Knowledge Portal is your one-stop platform for resources on space-based disaster risk management. It provides: • Links and guidance on satellite data sources and applications • Recommended practices and step-by-step methodologies • Training materials and tutorials • Case studies and user stories from real-world applications • News and updates on UN-SPIDER activities, events, and global developments
Since its last major review in 2012, the Portal has evolved significantly. Now, we want to hear from you.
We invite you to take part in the 2025 evaluation of the UN-SPIDER Knowledge Portal!
On 3 June 2015, the Open Geospatial Consortium (OGC) GeoSemantics Domain Working Group will host a summit, "GeoSemantics: Standards Intersect Ontologies". This summit will be part of the OGC’s June 2015 Technical Committee meeting in Boulder, Colorado. The Summit’s central topic is the application of ontologies in standards-based geo-information infrastructures.
The idea of the Semantic Web has been around for well over 10 years, and more recently principles of Linked Data have been gaining a lot of momentum. The Semantic Web involves data elements and connections between them being published on the Web in order to provide concrete opportunities for experimentation in semantic applications. Well defined, community agreements on semantics hold considerable promise for solving harmonization and integration of geospatial data sources from different regions, domains, and communities. Due to the universality of location and time geospatial (and temporal) semantics particularly have potential for advancing integration of both geospatial and non-geospatial data. At the same time, ontologies are increasingly a part of formal information specifications and models. This OGC summit is focused on bringing the informal linked data and formal ontology worlds closer together in the geospatial standards development process. This Call is for participants to share knowledge, present examples, and address issues involving geospatial ontologies.
To be considered for participation in the summit, please send a short abstract of your proposed contribution (200 – 400 words) to Linda van den Brink (l.vandenbrink [at] geonovum.nl) so that we can develop a final agenda appropriate to the interests and backgrounds of the participants.
