Forest height estimation from X-band SAR

IEEE International IEEE International IEEE International Geoscience and Remote Sensing Symposium, 2004. IGARSS '04. Proceedings. 2004, 2004
Forest stand height is an important indicator of standing biomass for management purposes as well as for the assessment of carbon storage. In this paper we assess Intermap Star-3i X-band SAR interferometry products for forest height estimation. DEM data sets are initially assessed for accuracy, and are then used to estimate forest height.

Forest Height Estimation in Tropical Rain Forest using Pol-InSAR Techniques

2006 IEEE International Symposium on Geoscience and Remote Sensing, 2006
Tropical rain forest environments are highly complex and heterogeneous in terms of species composition and structure and is often difficult to access. Radar remote sensing is for large tropical regions the only available information source for monitoring.

SAR radargrammetry and scanning LiDAR in predicting forest canopy height

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
Our objective was to evaluate the accuracy of estimating forest canopy height when using scanning LiDAR and TerraSAR-X stereo radargrammetry. The study area was located in southern Finland. We used SAR radargrammetry and LiDAR to extract 3D point clouds to derive predictors used in the non-parametric prediction of forest canopy height.

A forest canopy height surface model for scene simulation

SIMULATION, 1987
A model of forest canopy heights can support realistic remote sensing scene simulation. The final pixel (x, y) array of canopy heights results from merging structural and statistical sub-models. The structural model considers tree crowns to be structural primitives and permits explicit specification of forest structural characteristics (crown forms and
