Austrian Aerial Map (Ölk): Cadastral Plan Sheets at 1:10,000 Scale

3922 triangulation sheets comprise the Ölk dataset, providing a cadastral plan or aerial map frame for Austria. Each sheet covers a 10,000 m x 10,000 m square, subdivided into four 5,000 m x 5,000 m squares representing 2,500 hectares in nature. The data is provided by Cooperation OGD Österreich and Wikimedia Österreich in ESRI SHAPE format under a CC-BY-4.0 license.

Use Cases

• Cadastral mapping and land parcel analysis based on the described sheet structure and scale.
• Georeferencing other spatial datasets using the consistent 10,000 m x 10,000 m grid framework.
• Creating base maps for regional planning based on the aerial map and cadastral plan data.

Strengths

• Consists of 3922 individual map sheets, indicating broad spatial coverage.
• Provides a defined geometric structure with sheets of 10,000 m x 10,000 m and a scale of 1:10,000.
• Available in the standard ESRI SHAPE format for geospatial analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• Row count is unknown, which may limit suitability assessment for large-scale statistical analysis.
