Kriging Interpolation on Major Canadian City Temperature Data using System for Automated Geoscientific Analysis (SAGA GIS)

Kriging Interpolation on Major Canadian City Temperature Data using System for Automated Geoscientific Analysis (SAGA GIS)

Purpose

The purpose of this tutorial is to provide a step-by-step guide to using the Kriging interpolation technique in SAGA GIS, a software that many users may not have encountered before. The tutorial will introduce the various types of Kriging and the key variables to consider during the process. By comparing results from a dataset with dense data points to one with sparse data, the tutorial aims to highlight the critical role that data quality and quantity play in achieving accurate interpolation results.
