Luquillo CZO Rio Blanco and Rio Mameyes Lidar Survey 2010-2011

Welcome Guest   ( Sign In )

Overview

High-resolution Lidar data were obtained by NCALM for 253 km2 of the Luquillo Critical Zone Observaotry (LCZO) in the Rio Mameyes, Rio Blanco watersheds and coastal zones, Puerto Rico. Due to weather, the data were collected over two campaigns in July 2010 and May 2011, covering the entire survey area. Data acquisition, ground-truthing, vegetation surveys and processing were founded and coordinated by NSF Award EAR-0922307 (PI. Qinghua Guo) to collect similar data at all six CZOs for a variety of cross-site analyses, including calibration of algorithms to extract vegetation characteristics from the Lidar point cloud data.
