Mapbox has enhanced its global terrain layer to create a more realistic 3D experience, known as Mapbox 3D Terrain, which serves as a foundational canvas for applications requiring engaging or informative 3D elevation visuals. This update significantly improves the consistency and accuracy of terrain data, especially in areas with previously lower quality data, allowing for smoother and more realistic representations of geographic features. The enhancements include adding new data in regions like Greenland and Antarctica, improving detail in Canada and Western Europe, and refining coarse data in high latitudes. The improved terrain layer benefits applications where elevation is critical, such as outdoor maps and navigation in mountainous areas, and can be utilized by customers building 3D styles using Mapbox Studio.
