Master tracks in different resolutions during POLAR 2 campaign EPICA_III

This dataset was created via processing of raw position data acquired by the GPS sensor for scientific equipment on Polar 6/Polar 5 to receive a validated master track which is used as reference of further expedition data.

本数据集通过处理搭载于Polar 6/Polar 5的科学仪器配套的GPS传感器采集的原始位置数据，生成经验证的主航迹，该主航迹将作为后续科考航次数据的参考基准。
