Mapping forest canopy height globally with spaceborne lidar

Marc Simard, Naiara Pinto, Joshua B. Fisher, Alessandro Baccini
2011 Journal of Geophysical Research  
We present a wall-to-wall, global map of canopy height at 1-km spatial resolution, using 2005 data from the Geoscience Laser Altimeter System (GLAS) aboard ICESat (Ice, Cloud, and land Elevation Satellite  ...  A challenge in the use of GLAS data for global vegetation studies is the sparse coverage of lidar shots (mean = 121 data points/degree 2 for the L3C campaign).  ...  The research was carried out at the Jet Propulsion Laboratory, California Institute of Technology, under a contract with the National Aeronautics and Space Administration.  ...

Development and Evaluation of Predictive Models for Measuring the Biological Integrity of Streams

Charles P. Hawkins, Richard H. Norris, James N. Hogue, Jack W. Feminella
2000 Ecological Applications  
The ratio of the number of observed taxa to that expected to occur in the absence of human-caused stress (O/E ) is an intuitive and ecologically meaningful measure of biological integrity.  ...  O/E values derived from both species models were related to land use variables, but only assessments based on the P c Ն 0.5 model were insensitive to naturally occurring differences among streams, ecoregions  ...  We thank Mike Barbour for reading an early draft of the manuscript, Mark Vinson for reading later drafts, and two referees whose comments allowed us to clarify a few potentially confusing issues.  ...
