Regional Geotechnical Mapping Employing Kriging on Electronic Geodatabase

Regional Ionosphere Mapping with Kriging and B-spline Methods

The distribution of electrons in the ionosphere is of interest to scientists and also to engineers working on applications such as earth–space communication systems, which must transmit through the ionosphere, and skywave systems, which make use of ionospheric refraction. Electron content is commonly examined using total electron content (TEC) mapping. This mapping finds use in other applicatio...

Exploratory disease mapping: kriging the spatial risk function from regional count data

BACKGROUND: There is considerable interest in the literature on disease mapping to interpolate estimates of disease occurrence or risk of disease from a regional database onto a continuous surface. In addition to many interpolation techniques available the geostatistical method of kriging has been used but also criticised. RESULTS: To circumvent these critics one may use kriging along with alre...

Mapping Spatial Thematic Accuracy Using Indicator Kriging

Mapping geogenic radon potential by regression kriging.

Radon ((222)Rn) gas is produced in the radioactive decay chain of uranium ((238)U) which is an element that is naturally present in soils. Radon is transported mainly by diffusion and convection mechanisms through the soil depending mainly on the physical and meteorological parameters of the soil and can enter and accumulate in buildings. Health risks originating from indoor radon concentration...

Regional Seismic Event Characterization Using a Bayesian Kriging Approach

This effort focuses on collecting and analyzing regional seismic data for earthquakes and underground explosions to improve seismic event characterization capabilities with regard to monitoring the Comprehensive Nuclear-Test-Ban Treaty (CTBT). Digital data have now been acquired and processed for 267 regional recordings of 160 underground nuclear (UNE) and chemical (UCE) explosions. The explosi...
