Cognised existence: Orthoimagery is a geometrically corrected aerial or satellite photograph — the surface as seen from above, with positional accuracy. It is the most intuitive spatial data: it shows what the world looks like.
Question: What does the Earth’s surface look like at a location?
Realisations
Instead of hardcoding implementation schemas here, SPHERE separates semantic meaning from dataset implementation. See the following realisations for how to access this data:
Cross-Domain Relevance (Threads)
- Toposphere Imagery & Evidence: Imagery is direct visual evidence of surface state at acquisition time.
- Socio-Technical Perception & Thematics: Thematic classifications derived from imagery belong to human interpretive partitioning layers.
