Toward a spatialized index of the “benthic ecological state” using a new Coral Reef Rapid Assessment Method (CORRAM): case study at Reunion Island

Environmental and Sustainability Indicators
The development of a spatial index that can be used to represent the benthic ecological state of coral reefs is essential for guiding public conservation policies. We propose the spatialization of a new index of “benthic ecological state” using the Coral

Estimation of Spatial Coherency Functions for Kriging of Spatial Data

Journal of the Korean Society of Surveying, Geodesy, Photogrammetry and Cartography, 2016
In order to apply Kriging methods for geostatistics of spatial data, an estimation of spatial coherency functions is required priorly based on the spatial distance between measurement points. In the study, the typical coherency functions, such as semi-variogram, homeogram, and covariance function, were estimated using the national geoid model. The test

GAMs and functional kriging for air quality data

, 2016
Data having spatio-temporal structure are often observed in environmental sciences. They may be considered as discrete observations from curves along time and/or space and treated as functional. Generalized Additive Models (GAMs) represent a useful tool for modelling, for example, as pollutant concentrations describing their spatial and/or temporal ...

Mechanical Characteristics Analysis and Structural Optimization of Wheeled Multifunctional Motorized Crossing Frame

Applied Sciences
Wheeled multifunctional motorized crossing frames represent a new type of crossing equipment for high-voltage transmission line construction. The initial design is too conservative, having a large safety margin and high material redundancy. Therefore, it

Geostatistics for functional data: an ordinary kriging approach

, 2007
We present a methodology to perform spatial prediction when measured data are curves. In particular, we propose both an estimator of the spatial correlation and a functional kriging predictor. We adapt an optimization criterium used in multi- variable spatial prediction in order to estimate the kriging parameters.

Application of Moving Kriging Shape Functions on Plate Problems

NUST Journal of Engineering Sciences, 2008
The Moving Kriging (MK) interpolation was recently proposed as a superior substitution of the Moving Least Square (MLS) approximation in the construction of shape functions for the Element-Free Galerkin Method (EFGM). Although Kriging is already a very well­ known geo-statistical technique for spatial interpolation in geology and mining, it has only ...
