Side-Selective Line Simplification Results for Nautical Charts

Six testbed results for a cartographic line-simplification algorithm designed for nautical charting. The algorithm constrains line displacement, segment length, and bend geometry using scale-driven parameters expressed in millimeters. The work was authored by Christos Kastrisios and uploaded in April 2026.

Use Cases

• Evaluate algorithm performance on line displacement constraints across six different testbeds.
• Analyze the effect of segment length parameters on the visual coherence of simplified contours.
• Validate bend geometry preservation in simplified lines against cartographic practice standards.
• Compare simplified output contours against original data to assess compliance with nautical safety constraints.

Strengths

• Results provided for six distinct testbeds for comparative analysis.
• Algorithm parameters are human-interpretable and expressed in millimeters at the target scale.

Limitations

• The dataset is small at 7.3 MB, limiting the scope of analysis.
• Unknown row count and specific column structure for the result data.
