title: DHMOprindelse draft: false type: register
DHMOprindelse is the provenance register for Danmarks Hojdemodel products and acquisition context. It is a core component of Grunddatamodellen.
This page inherits shared contracts from Grunddatamodellen and only documents elevation-source interpretation:

Agent Start Here
| User need | Start leaf | Primary entities | Spatial path | Time rule |
|---|---|---|---|---|
| Retrieve elevation products and provenance | |Elevation | DHM source and provenance entities | raster/point-cloud access | use acquisition date and campaign metadata |
| Compare contour or terrain derivatives | |Elevation | DHM provenance + derived products | DHM → contour derivatives | match derivative to source campaign |
Minimum Interpretation Rules
- This register describes source lineage and acquisition context rather than being the elevation surface itself.
- Use it to explain quality, origin, and campaign differences across DHM products.
Access Strategy
- Start from Elevation for most terrain questions.
- Use this collection when provenance, acquisition quality, or source differentiation is the analytical requirement.
