An Improved Generalized Hierarchical Estimation Framework with Geostatistics for Mapping Forest Parameters and Its Uncertainty: A Case Study of Forest Canopy Height
forest up-scaling regression kriging uncertainty LiDAR
2023/12/1
Forest canopy height is an essential parameter in estimating forest aboveground biomass (AGB), growing stock volume (GSV), and carbon storage, and it can provide necessary information in forest manage...
Application of Model-based Geostatistics for Natural Hazards Identification
Model-based geostatistics Ordinary kriging Kriging with external drift Natural hazard
2015/12/1
Annually much agricultural productions are lost by natural hazards such as flooding, extreme temperature, and drought. In this research we present a procedure to identify such hazards for rice croppin...

2015/9/28
This paper is continuation work of a research started in 2005. In the previous research, variety of fuzzy digital elevation models was constructed and the best fit model was selected in order to prese...
MAPPING LAND COVER CHANGES WITH LANDSAT IMAGERY AND SPATIO-TEMPORAL GEOSTATISTICS;AN APPLICATION TO THE PEARL RIVER DELTA,CHINA
Kriging Variogram Edges Context Transitions probability Combining priors
2015/8/3
The use of remote sensing to monitor rapidly growing cities is challenging due to the dynamics of the landscape. Mapping of these land cover changes calls for an integrated algorithm that can detect b...
USE OF GEOSTATISTICS TO INTEGRATE INTERFEROMETRIC SAR DATA WITH LEVELING MEASUREMENTS OF LAND SUBSIDENCE
GEOSTATISTICS INTERFEROMETRIC SAR DATA LEVELING MEASUREMENTS LAND SUBSIDENCE
2015/6/1
D-InSAR data of ground surface deformation have uncertainty caused by several sources associated with image acquisitions and data processing. In this study, these data are modeled as the sum of a tren...

Top-kriging - geostatistics on stream networks
Top-kriging - geostatistics stream networks streamflow-related variables
2009/5/13
We present Top-kriging, or topological kriging, as a method for estimating streamflow-related variables in ungauged catchments. It takes both the area and the nested nature of catchments into account....
