Abstract
Assessment of Kriging Accuracy in GIS EnvironmentTrack: Modeling
Author(s): Peter Paul Siska, I-K Hung
The demand for spatial data is on the rise. However, even the latest technology cannot guarantee an error free GIS database. In natural resources the point field sampling is often used for spatially oriented projects. Spatial interpolation methods are used to predict the values in unsampled locations and for generating maps. In this project, the errors from GIS kriging interpolation were studied, analyzed, and modeled. The sensitivity of GIS kriging to a predicted grid was evaluated and compared with a geostatistical program. The findings of this study will be useful for a variety of GIS practicioners who are using kriging interpolation in a GIS environment.
