SamplyCity

Simple samples of CityGML 3.0 in the name of simplicity.

  • Stage 1 (Progress: %95) : SamplyCity aims to reflect regularly used geometry representations in CityGML 3.0 files.
  • Stage 2 (Progress: % 60): SamplyCity aims to consist at least one sample per module.
  • Stage 3 (Progress: 30%): SamplyCity aims to reflect all possible data structure scenarios within itself.

SamplyCity Manifest

  • No decimal coordinates.
  • Less vertices as much as possible.
  • Hierarchical (GML)ID assignment for all the features.
  • Document the results of the experiments with different software/tools for every file individually.

A visualization of the most used geometry representations in CityGML 2.0/3.0

This visual is designed to represent the hierarchical data structure of GML geometries reversly (from sub to superb).
