In support of the DESDynI mission, we have been performing ground validation work at the Harvard Forest in Western Massachusetts, and collaborating with Aberystwyth University on securing similar ground validation data for the Injune region, located in Queensland, Australia. These forest types reflect mature, transitional hardwood forests and savanna woodlands, two stable landcover types that serve as an ideal targets for the development of algorithms for relating spaceborne observations from Lidar and SAR/InSAR to vegetation structural characteristics. For both of these biomes, commensurate lidar and SAR/InSAR data are available for correlating with the ground validation measures of structure. These data sources consist of terrestrial scanning lidar, airborne lidar, and spaceborne L-band SAR (both locations are cal/val sites for JAXA's ALOS-PALSAR). Additionally, the Harvard Site was recently images by NASA's UAVSAR and LVIS sensors, for the purpose of generating a superset of data that is currently being processed.
In this poster, we i.) summarize the variety of ground validation data available at these sites, ii.) summarize the variety of remote sensing data that will be used for developing DESDynI-related products, and iii.) present recent results from analysis and observation of the Harvard and Injune forests using both lidars and spaceborne SAR/INSAR.
