Welcome to SemanticGIS.ORG. This site presents international and global geospatial datasets organised according to the principles of SemanticGIS — a semantic framework for reasoning about spatial data across sources, scales, and domains.
For Danish national data, see semanticgis.dk.
How to Navigate Data
1. By Sphere (Semantic Domains)
Navigate by thematic interest. Spheres organise the world into domains — Socio-Technical, Atmosphere, Biosphere, Hydrosphere, Lithosphere, Pedosphere, Toposphere — each decomposed into leaves that answer specific spatial questions.
- Best if you are asking a research question (e.g., “Where are buildings?”, “What is the elevation?”, “Where are protected habitats?“)
- Each leaf links to the international datasets that realise it
2. By Collection
Browse by dataset programme or collection — OSM, Copernicus, Natural Earth, Overture Maps, and others.
3. By Data Portal
Understand how to access data from each international source: query patterns, auth, service types.
