TanDEM-X Forest/Non-Forest Map - Global

The TanDEM-X Forest/Non-Forest Map is a project developed by the Microwaves and Radar Institute at the German Aerospace Center (DLR), within the activities of the TanDEM-X mission. The goal is the derivation of a global forest/non-forest classification mosaic from TanDEM-X bistatic interferometric synthetic aperture radar (InSAR) data, acquired for the generation of the global digital elevation model (DEM) in Stripmap single polarization (HH) mode.


The TanDEM-X Forest/Non-Forest Map (FNF) has been generated by processing and mosaicking more than 500,000 TanDEM-X bistatic images acquired from 2011 until 2015. The map has a spatial resolution of 50 x 50m. Forested and non-forested areas are depicted in green and white, respectively. Water bodies are depicted in blue and black is used for identifying urban areas and invalid pixels.

Statement

The TanDEM-X global Forest/Non-Forest map dataset is based on the TanDEM-X bistatic interferometric synthetic aperture radar (InSAR) data. Using a fully automated InSAR processing and mosaicking system, more than 500,000 quicklook SAR images (50 m ground resolution), acquired between 2011 and 2015 and covering twice the Earth’s land surface, have been analyzed. Thereby, the volume correlation factor of the InSAR data have been used in combination with several TanDEM-X observables such as the bistatic coherence, the calibrated amplitude, and the digital elevation model (DEM) height information to distinguish between forested and non-forested areas on the Earth in a completely automated, complex decision-making process.
