Abstract

Two semi-empirical approaches suitable for forest tree height retrieval from interferometric SAR images were developed in this study. Methods developed are mainly meant for cases when reference elevation model is missing. Spaceborne interferometric SAR data from TanDEM-X mission was used in the study. The study site was located in the south-eastern part of the state of Chiapas, Mexico. The TanDEM-X images were acquired during spring and summer 2012. The height estimates obtained in the study varied between 15 and 35 meters in the area of interest covered by the TanDEM-X images. The Pearson's correlation coefficient between estimated tree heights and reference ground plots form National Forest Inventory were 0.25 and 0.32 for maximum and average tree height measures, respectively. This work on tropical forest tree height retrieval from interferometric TanDEM-X images was performed within the EU FP7 project ReCover
