Chapter 2 - Merits and Demerits of GIS and Geostatistical Techniques

Abstract

The spatial reference of GIS data has special characteristics but with advantages and disadvantages of geostatistical methods. The geostatistical techniques relies on assumptions made as well as observation and provides optional methods to be chosen based on the end user requirements. This chapter gives a glimpse of the fundamentals of geostatistical methods and elaborates the merits and demerits of the spatial representation that uses GIS techniques. GIS technique in the geospatial operations is merely a collection of tools to capture, store, analyze, and manage and to present with respect to graphical locations of the domain. Though the geostatistical referenced data has its own limitations, errors could be minimized provided assumptions made are to be remembered. The output of GIS analysis reflects on the uncertainties that are related to input data quality. Better understanding of the spatial data and the review of dimensions in the input spatial data can overcome the errors.
