Geostatistics Assignment Help

Geostatistics can be defined as a specialized branch of statistics dealing with the analysis and interpretation of spatial or spatiotemporal data. It plays an immense role in earth sciences and many other environmental studies. Get specialized advice from a Geostatistics assignment expert to enhance your understanding and performance.

Key Concepts

The core of geostatistics is the idea of spatial dependence, on which the dependence between values assigned at different locations should be. This spatial autocorrelation is modeled by random functions where each location in space is considered as a random variable. One main assumption, stationarity, involves that the statistical properties of spatial data are not changing over the space; it eases the modeling process.

Types Of Geostatistical Methods

• Kriging is the most versatile interpolation method, providing linear unbiased predictions of the best data spatial.
• Variogram Analysis is a quantification of spatial correlation among sample points; thus, it is the basis of geostatistics.
• Simulation Techniques are those that generate any number of realizations of spatial phenomena and, therefore, the possibility of examining uncertainty or variability.

The Variogram: Basic Tool

Geostatistics is based on the concept of the variogram, which is the summary characterization of the features of the spatial correlation structure within the data. The basic parameters of the variogram include the range, nugget, and sill. These parameters respectively refer to the distance at which one measurement is conditionally correlated to another, the maximum variance and the micro-scale variation, or measurement error. A variogram captures the general shape of the data cloud and is hence important for the modeling of the spatial pattern in geostatistics.

Kriging Techniques

Simple Kriging is the basic form of kriging and provides a form of spatial interpolation with the underlying assumption of stationarity. Ordinary Kriging is a standard form of kriging in which, unlike simple kriging, the empirical variogram is not directly modeled—a general or theoretical variogram stack is used instead. Universal Kriging is more sophisticated and allows for trend apparent in the data. Indicator Kriging is used with data observed at a categorical level and can provide more flexibility for the analysis of more diverse types of spatial data. Too busy to complete your assignment?

Geostatistical Simulations

• Sequential Gaussian Simulation:  It allows one to draw realizations of continuous spatially distributed variables.
• Indicator Simulation:  This is used in the modeling of categorical.
• Direct Simulation:  It allows a direct generation of the spatial patterns based on the specified statistical properties. Stuck on your homework? Our Geostatistics homework help is here to clarify tricky concepts.

Geostatistics Applications

• Resource Estimation: The geostatistical techniques are mainly dependent on the mining and petroleum industries for resource estimation both in terms of quantity and quality.
• Environmental Monitoring: This includes pollution monitoring, the risk assessment of one strategy over another and planning for cleaning of contaminated sites.
• Agricultural Planning: Geostatistical soil mapping benefits agricultural planning by using precision farming for optimized resource uses, like nutrients for specific crop areas and lowers the socio-environmental negative externalities cost.
