Worked on the NavigaTUM repository to enhance the accuracy of indoor map-view features by addressing floor-level misalignments for Points of Interest (POIs), specifically Validierungsautomaten. Focused on data configuration using YAML, the developer updated the 21_pois.yaml file to introduce more precise parent identifiers, which improved the reliability of floor matching within the application. This data-driven approach established a more robust POI hierarchy, reducing mapping errors and laying the groundwork for easier future updates to the POI data pipeline. The work emphasized careful modeling and configuration, contributing to a more dependable user experience in indoor navigation scenarios.
