Module 2. Getting Started with QGIS
Welcome to our tutorial on "Getting Started with QGIS". In this module, we explore the definition and functions of the Geographic Information System (GIS) as well as installation, default settings and layout, key technical functions, and basic operation of the QGIS software.
GIS is an information system designed to efficiently utilize geographic information necessary for human life by converting it into computer data. And an information system refers to a system that collects, observes, measures, inputs, stores, manages, and analyzes information to generate information necessary for decision-making. GIS integrates and manages spatial data and attribute data to provide various forms of information such as maps, charts, and diagrams. Since GIS handles all kinds of data closely related to human real life, it has a wide range of applications. The applications of GIS are rapidly expanding across various industries including land, resources, cities, environment, transportation, agriculture, marine, and defense.
Through the process of spatial analysis, GIS is utilized for analyzing scenarios for various plans or policy-making, operating decision-making models, and detecting & analyzing changes. The core function of GIS is to provide an environment where diverse geometric and attribute data can be extracted and combined from numerous data files, enabling comprehensive information analysis and processing.
Then, how can GIS support the Impact-based forecasting warning services? GIS can be of help in forecasting the impacts of a seasonal climate conditions or a natural hazard event on population, energy powerplant, airport, and any other types of assets. And the maps shown on the screen, as examples, illustrate the likely impacts of seasonal forecasts and natural hazard analyzed and visualized by the GIS software.
Join us as we delve into basic operation of QGIS, which will make you capable of creating and exporting a basic map with legend, north sign, scale bar, and disclaimer notes, after completing the module.
