Ash Steep Edges in Groningen Province from AHN3 Elevation Data

Steep edges of ash located within the province of Groningen in the Netherlands. The data shows these features on the transition to brook valleys where there is a minimum height difference of 0.5 meters. The dataset is provided by the Dutch Ministry of the Interior and Kingdom Relations and has been updated to the AHN3 elevation model.

Use Cases

• Map terrain discontinuities based on the defined 0.5-meter height threshold.
• Analyze the transition zones between ash features and brook valleys.
• Integrate with other geospatial layers for regional environmental modeling in Groningen.

Strengths

• Features are defined by a specific, measurable criterion (0.5-meter height difference).
• Data is sourced from the authoritative AHN3 (Actueel Hoogtebestand Nederland) elevation model.
• Published under a permissive public domain license (CC-PDM-1.0).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
