How tall the world's mangrove forests are, from Germany's TanDEM-X radar satellites (2015)
What it measures. How tall mangrove forests stand around the world in 2015, including the height of the tallest trees, mapped at 12 m detail.
How it's made. Calculated from the German Space Agency's TanDEM-X radar (which builds 3D surface models), with NASA's GEDI space laser measurements used to train and check the heights.
How & where you'd use it. Helps researchers study mangrove forest structure, the local conditions that shape it, and how much carbon these coastal forests store and cycle.

Official description
This dataset characterizes canopy heights of mangrove-forested wetlands globally for 2015 at 12-m resolution. Estimates of maximum canopy height (height of the tallest tree) were derived from the German Space Agency's TanDEM-X data that produced global digital surface models. Also provided are Lidar estimates of canopy height based on the GEDI instrument, which were used for training and validation of the TanDEM-X estimates of forest height. The coverage of these data follows Global Mangrove Watch's mangrove extent maps. These spatially explicit maps of mangrove canopy height can be used to assess local-scale geophysical and environmental conditions that may regulate forest structure and carbon cycle dynamics. Maps revealed a wide range of canopy heights, including maximum values (>60 m) that surpass maximum heights of other forest types. Maps are provided in cloud optimized GeoTIFF format, and mangrove heights for individual GEDI tiles are compiled in a comma separated values (CSV) files.
