Skyline Datasets: 2D Point Coordinates from K2-Tree Query Experiments

Datasets from Skyline query experiments over k2-tree representations. The collection is 10.6 GB in size and was authored by Martita Muñoz, with a last update in April 2026. Files are in plain text format, with each line encoding a 2D point as a pair of coordinates.

Use Cases

• Benchmarking skyline query performance based on the described k2-tree representations.
• Developing or testing spatial indexing algorithms based on the provided 2D point coordinate data.
• Researching computational geometry and multi-criteria optimization using the experimental query results.

Strengths

• Dataset size is 10.6 GB, indicating a substantial volume of data for analysis.
• Data is openly available under a CC-BY-4.0 license, facilitating reuse and sharing.
• The description specifies the data format and structure, with each line encoding a 2D point.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific tasks.
• Description metadata is limited; actual data quality requires manual inspection after download.
