Data Set Overview
|Data set||CMS: LiDAR-derived Tree Canopy Cover for Pennsylvania, USA, 2008|
|Project||Carbon Monitoring System (CMS)|
|Time Period||2006-01-01 to 2010-12-31|
This data set provides estimated high-resolution (1-m) tree canopy cover for the state of Pennsylvania, USA, in 2008. The data were derived from 2006-2008 county-level Light Detection and Ranging (LiDAR) data, 2010 leaf-on agricultural imagery, and county building polygon data. The data were processed with a rules-based expert system which facilitated integration of imagery and LiDAR into a single classification workflow, utilizing the spectral, height, and spatial information contained in the data sets to estimate tree canopy cover. A 1 x 1-m pixel was identified as having tree canopy present (value=1) when it (1) contained an object 2-m or higher, (2) was not a known building and/or (3) had a complex LiDAR return structure (typically trees) as compared to those with a simple return structure (typically buildings).

Carbon Monitoring System (CMS): The NASA Carbon Monitoring System (CMS) is designed to make significant contributions in characterizing, quantifying, understanding, and predicting the evolution of global carbon sources and sinks through improved monitoring of carbon stocks and fluxes. The System will use the full range of NASA satellite observations and modeling/analysis capabilities to establish the accuracy, quantitative uncertainties, and utility of products for supporting national and international policy, regulatory, and management activities. CMS will maintain a global emphasis while providing finer scale regional information, utilizing space-based and surface-based data and will rapidly initiate generation and distribution of products both for user evaluation and to inform near-term policy development and planning.
