This is an interesting site dealing with the fusion of lidar and IFSAR data. It is hosted by the USGS, the Forest Service and others.

A major component of this project was the development of specialized remote sensing software systems that could efficiently process, analyze, and display the extremely large LIDAR and IFSAR datasets that were acquired over the study sites.  For instance, there are 40 million data points in the LIDAR dataset covering the 2 square mile Blue Ridge study site and approximately 10 times this amount of data covering the Mission Creek site.  Commercial remote sensing packages did not have the capacity to handle such large datasets.

Thanks to Brent Gelhar for the heads up.
