  Greenland, the world’s largest island, has one of the most challenging environments for geodetic measurements. Maintaining GNSS (Global Navigation Satellite Systems) stations here isn’t just about precision – it’s about ensuring data continuity in an area that’s constantly moving. This is the behind-the-scenes story of a 15,000 km journey around Greenland: five weeks of helicopter-bas ...[Read More]

Effective scientific communication of geodetic research often relies on clear visualizations, and colours are needed to make complex data much easier to understand. However, traditional colormaps don’t always provide the needed clarity and can be especially challenging for people with colour-vision deficiencies (CVD). In this post, we will first describe what CVD is and how it is present in academ ...[Read More]
