HPI, Geomatics Applied Learning Program Description
Have you wondered how Google is able to create the 3D models that you use everyday when searching for a place in Google Earth? Now you can do it yourself using QGIS. This program will teach you how to process LiDAR and orthophotos to create 3D scenes of Mount St. Helens and Glasgow, Scotland.
You will learn how to install Quantum GIS (QGIS) with plugins, perform vector and raster analysis using the MacOS Operating System. I will walk you through each stage using step-by-step lectures and imagery. This program uses datasets based on real-life circumstances using open-source QGIS software. You will learn the history behind Geographic Information Systems and how open-source (free) GIS software can be leveraged to help solve real world issues.
Students will learn how to start a GIS project and change the coordinate system of vector feature datasets.
Students will learn how to georeference a scanned paper map of Alberta, Canada, using the QGIS Georeferencer Tool.
Students will learn how to create a new Layout and Publish their maps to industry standard formats (e.g., Print, Image, and Geo-PDF) using the QGIS Layout Manager.
Students will learn how to enhance, process, and analyze Sentinel 2 datasets of Tonga–Hunga Haʻapai Volcano Island and Tonga Island to determine vegetation changes between 2021 and 2022.
Students will learn how to use the Orfeo Toolbox, supervised classification machine learning algorithms to detect vegetation changes of Walnut Trees in and around Vinay, France.
Students will learn how to perform a Terrain Analysis of Mt. St. Helens, creating a Digital Surface Model (DSM) and displaying it as a high-resolution 3D scene.
Students will learn how to process LiDAR point file datasets into Digital Surface Model (DSM) and Digital Terrain Models (DTM) to create, 2, 4, 6, 8 and 10m Sea Level Rise maps of Glasgow, Scotland.
There are many possible applications of GIS in other areas. For example, in view of the increasing frequency and severity of extreme weather events, it would be possible to determine the vulnerability of towns and cities to risks such as flooding, wind damage and wildfires.
