VEGETATION DISTURBANCE AND RECOVERY FOLLOWING A RARE WINDTHROW EVENT IN THE GREAT SMOKY MOUNTAINS NATIONAL PARK
tornado Landsat Enhanced Vegetation Index EVI time-series Southeastern United States
2016/11/30
The tornado outbreak of April 2011 in the Southeastern United States caused major damage to property and natural ecosystems. During the outbreak, the Great Smoky Mountains National Park (GRSM) was hit...
RESPONSE OF RIPARIAN VEGETATION IN AUSTRALIA"S LARGEST RIVER BASIN TO INTER AND INTRA-ANNUAL CLIMATE VARIABILITY AND FLOODING AS QUANTIFIED WITH LANDSAT AND MODIS
riparian vegetation flooding river basin climate variability
2016/11/30
Australia is a continent subject to high rainfall variability, which has major influences on runoff and vegetation dynamics. However, the resulting spatial-temporal pattern of flooding and its influen...
LIGHT DIFFUSION IN THE TROPICAL DRY FOREST OF COSTA RICA
Leaf area index spectral vegetation indices MODIS
2016/11/30
Leaf Area Index (LAI) has been defined as the total leaf area (one-sided) in relation to the ground. LAI has an impact on tree growth and recruitment through the interception of light, which in turn a...
ACCURACY ASSESSMENT OF CROWN DELINEATION METHODS FOR THE INDIVIDUAL TREES USING LIDAR DATA
Forest Canopy LiDAR Pit-free Stand-level
2016/11/30
Forest canopy density and height are used as variables in a number of environmental applications, including the estimation of biomass, forest extent and condition, and biodiversity. The airborne Light...
EVALUATION OF FOREST CANOPY AND UNDERSTORY GAP FRACTION DERIVED FROM TERRESTRIAL LASER SCANNING
Forest structure Understory Gap fraction Terrestrial laser scanner
2016/11/30
The quantification of forest carbon sequestration is helpful to understand the carbon storage on the Earth. The estimation of forest carbon sequestration can be achieved by the use of leaf area index ...
FOREST TREE SPECIES DISTRIBUTION MAPPING USING LANDSAT SATELLITE IMAGERY AND TOPOGRAPHIC VARIABLES WITH THE MAXIMUM ENTROPY METHOD IN MONGOLIA
Tree species mapping Landsat imagery Maximum Entropy Terrain variable Mongolia
2016/11/30
Forest is a very important ecosystem and natural resource for living things. Based on forest inventories, government is able to make decisions to converse, improve and manage forests in a sustainable ...
DEFORESTATION ALONG THE MAYA MOUNTAIN MASSIF BELIZE-GUATEMALA BORDER
Deforestation Transboundry Maya Mountain Massif Protected Areas Biodiversity Belize
2016/11/30
In recent years trans-boundary incursions from Petén, Guatemala into Belize’s Maya Mountain Massif (MMM) have increased. The incursions are rapidly degrading cultural and natural resources in Belize’s...
ANALYSIS OF THE SIDE-LAP EFFECT ON FULL-WAVEFORM LIDAR DATA ACQUISITION FOR THE ESTIMATION OF FOREST STRUCTURE VARIABLES
LiDAR full-waveform overlap stripe differences density changes forest structure canopy fuel comparison of paired samples
2016/11/30
LiDAR full-waveform provides a better description of the physical and forest vertical structure properties than discrete LiDAR since it registers the full wave that interacts with the canopy. In this ...

Mangroves Rhizophoraceae Plantation Point Cloud LiDAR
2016/11/30
Estimating the structural and functional attributes of forests is integral in performing management strategies and for understanding forest ecosystem functions. Field sampling methods through plot lev...
IMPACTS OF TREE HEIGHT-DBH ALLOMETRY ON LIDAR-BASED TREE ABOVEGROUND BIOMASS MODELING
tree aboveground biomass lidar allometric equations simulation regression
2016/11/30
Lidar has been widely used in tree aboveground biomass (AGB) estimation at plot or stand levels. Lidar-based AGB models are usually constructed with the ground AGB reference as the response variable a...
