Solar and Green Roof Potential Cadaster for Linz, Austria

A geospatial dataset from the city of Linz assesses roof suitability for photovoltaic systems, solar thermal systems, and green planting based on solar radiation and roof inclination. The data foundation uses altitude data provided by the State of Upper Austria and incorporates experience values from the city combined with the ÖNORM L1131 standard for building greening. It is published under a CC-BY-4.0 license by the cooperation OGD Österreich and Wikimedia Österreich.

Use Cases

• Identify suitable roofs for photovoltaic panel installation based on solar radiation data.
• Assess roof viability for solar thermal systems based on roof inclination.
• Evaluate potential for green roof planting projects on residential and commercial buildings.
• Perform cost-benefit analysis for solar installations using the integrated cost-effectiveness calculator.

Strengths

• Data is based on authoritative altitude data sourced from the State of Upper Austria.
• Analysis incorporates a recognized building standard (ÖNORM L1131) and local municipal experience.
• Dataset includes an integrated cost-effectiveness calculator for photovoltaic/solar potential.

Limitations

• Row count and dataset size are unknown, limiting suitability assessment for large-scale analysis.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.

Provenance
