A comparison of spatial interpolation techniques in temperature estimation
Spatially distributed estimates of meteorological data are becoming increasingly important as inputs to spatially explicit landscape, regional, and global models. Accurate estimates of meteorological values such as temperature, precipitation, and evapotranspiration are required for a number of …

A Comparison of Spatial Interpolation Techniques for Determining Shoaling Rates of the Atlantic Ocean Channel
… cross section of a survey. Using a variety of spatial interpolation methods, depths of these unmapped areas were produced. The choice of spatial interpolator varied upon which method adequately produced surfaces from large hydrographic survey data sets with the lowest amount of prediction …

Evaluation of Spatial Interpolation Techniques Built in the Geostatistical Analyst Using Indoor Radon Data for Ohio,USA
… six geographical information system (GIS) based interpolation techniques to estimate the radon concentration in the unmeasured zip codes in the State of Ohio. The radon concentration in homes has been obtained by The University of Toledo researchers from various commercial testing services, …

A New Analog for Numerical Flow Simulations Application to Direct Assessment of Reservoir Flow Performance Uncertainties
… to manytraditional, computationally expensive techniques such as Monte Carlo simulations. This is achieved via a single stochastic flow simulation that combineslocal geologic uncertainty with a new simple flow transfer model to estimate a joint uncertainty distribution that characterizes flow …

Fractal relationships and spatial distribution of ore body modelling
The nature of spatial distributions of geological variables such as ore grades is of primary concern when modelling ore bodies and mineral resources. The aim of any mineral resource evaluation process is to determine the location, extent, volume and average grade of that resource by a trade off …

Part I: Geostatistical Interpolation of Rain Fields Using Radar Estimates and Gauge Observations: Algorithm Design and Automation; Part II: Energy Dissipation in Fluid Flows and Wave Transformation by Porous Barriers and Submerged Cavities
… part aims to improve the accuracy of rain field interpolation with the utilization of radar rainfall during extreme storm events for a study watershed. The second part studies the head loss induced by fluids passing through porous screens and the wave transformation caused by porous barriers as …

Modeling Stormwater Pollutant Transport in a Karst Region--Bowling Green, Kentucky
… in karst regions using GIS technologies and spatial analysis techniques – including identifying which data and techniques are essential to analyze surface and subsurface processes - to improve stormwater monitoring effectiveness. The premise of this study is broken down into a conceptual …

The legacy of arsenic: Identification of arsenic exposure potential and negative health outcomes
… to historic arsenic usage to investigate the spatial distribution of arsenic at the county level. Eight variables were summarized and categorized into two different types of arsenic indices that represent the arsenic distribution from natural occurrence and anthropogenic practices in Florida. …

Modeling forest stand structure using geostatistics, geographic information systems, and remote sensing
… phenomena, however, change gradually over space. Spatial interpolation techniques like geostatistical methods, can be applied to represent forest stand structure as a continuous surface. While traditional statistics assume independent data, geostatistics take a different approach by quantifying …

GEOGRAPHIC DATA MINING AND GEOVISUALIZATION FOR UNDERSTANDING ENVIRONMENTAL AND PUBLIC HEALTH DATA
… a very large amount of real-world facts and geospatial data are collected and stored. Decision makers cannot consider all the available disparate raw facts and data. Problem-specific variables, including complex geographic identifiers have to be selected from this data and be validated. The …
