Abstract:
The motivations
for this study are two twofold: (a) the need for spatially resolved
accurate estimates of forest woody biomass to improve our understanding
of the dynamics of source/sink relations in the terrestrial carbon
cycle, (b) characterizing changes in the three-dimensional structure of
forests in relation to natural and anthropogenic disturbances and
subsequent recovery within the context of habitat preservation,
biodiversity and resource management. The objective of this study is to
develop the research basis for remote sensing of variables descriptive
of 3D forest structure (tree height, crown height and diameter, ground
cover and tree density). The methodology is based on the novel idea of
retrieving the pair correlation function that uniquely characterizes
the horizontal structure of a forest stand by synergistically
exploiting the information content of lidar, multispectral and
hyperspectral remote sensing data. We propose to develop the
theoretical basis of this methodology and test it with experimental
data using existing ground and aircraft-based remote sensing data from
various sites in the USA. This proof-of-concept study is expected to
contribute to the development of operational algorithms for retrieval
of forest 3D structure as part of the proposed NASA DESDnyI mission.
