Purpose
The purpose of this tutorial is to introduce users to land use change assessment in SAGA GIS. This will be done two ways, in order to help users to choose which is best for their applications. There will be step-by-step instructions on how to use SAGA GIS to do this assessment.
Introduction
Land use change assessment
Land use change assessments can be useful to detect the extent of human influence on natural environment. This is often done by taking two satellite images from different time periods and classifying them, and then calculating the difference between both classified images. ADD MORE INFO.
SAGA GIS
SAGA GIS is a free open source software that can be run under Windows and Linux operating systems. SAGA stands for System for Automated Geoscientific Analysis. According to SAGA's website, it is a GIS that has been designed for an easy and effective implementation of spatial algorithms. It offers a comprehensive, growing set of geoscientifc methods and provides easily approachable user interface with many visualisation options.
