GeoBIM Benchmark 2019: CityGML Export Test Results

The GeoBIM benchmark 2019, an international scientific initiative, produced this dataset of CityGML files from Task 3. It contains results from an export test evaluating support for the CityGML standard, a format for 3D city models. The data results from collaboration with multiple participants in the benchmark, coordinated by Delft University of Technology.

Use Cases

• [Benchmarking software interoperability] based on [export test results for CityGML support]
• [Analyzing data conversion quality] based on [standardized 3D building model exports]
• [Researching BIM-GIS integration workflows] based on [the GeoBIM benchmark framework]
• [Developing validation tools] based on [comparative results from multiple participants]

Strengths

• Dataset is the product of a formal, funded scientific initiative by ISPRS and EuroSDR
• Results are derived from a collaborative benchmark involving multiple participants, suggesting comparative value
• Data is associated with a detailed project website providing full context and resources

Limitations

• Key metadata such as row count, file size, and specific column names are unknown
• The last update date is not provided, limiting assessment of freshness
• The dataset's scope is confined to a single task (Task 3) from a specific 2019 benchmark
