Cognised existence: Elevation is the vertical distance of a point on the Earth’s surface above a datum. It determines where water flows, where floods reach, how much sun a slope receives, and what is visible from a point.
Question: What is the elevation at a given location?
Realisations
Instead of hardcoding implementation schemas here, SPHERE separates semantic meaning from dataset implementation. The realisations are listed in priority order:
- Danmarks Højdemodel (DHM) (derived_modelled)
- Dataforsyningen Tile Services (derived_modelled)
Cross-Domain Relevance (Threads)
- Hydrosphere: Elevation drives water flow direction, flood modelling, catchment delineation. DTM is the foundation for hydrological analysis.
