The classes will be held on-line as Zoom sessions from 4:30 to 6 PM EDT.

Introduction to QGIS, September 8: https://libcal.princeton.edu/event/7010778

QGIS is an open-source GIS desktop software package. It has many features found in other desktop GIS software, runs on Linux/Unix, MacOS and Windows operating systems, and is available at no cost. Intended for anyone new to GIS technology, students will need to install QGIS on their own computers prior to the session.  QGIS may be downloaded from www.qgis.org.  Students should install the Long Term Release (LTR) version 3.10.x.  The session will show how to load geospatial data, add on-line map services, extract selected data, and make simple maps. The training may also be useful to users of other desktop GIS software. 

How to Create and Collect Geographic Data using QGIS, September 9: https://libcal.princeton.edu/event/7010813

In this class students will learn how to collect geographic data from Google maps and Google Earth, how to add GPS data to GIS software, and how to georeference a scanned map.  Students will need to install Google Earth and QGIS on their own computers prior to the session.  QGIS may be downloaded from www.qgis.org.  Students should install the Long Term Release (LTR) version 3.10.x. 

Select and Analyze Geographic Features and Data with QGIS, September 10: https://libcal.princeton.edu/event/7010815

QGIS has an excellent interface for exploring and analyzing spatial information. Point, line and area features (vector data) are both geographic objects on a map and records in a table. Such features can be selected by location or by the values stored in a feature’s record. These simple capabilities allow the GIS user to conduct complex analyses.  The session uses data for central New Jersey to calculate the area of land use types near streams, the extent of paved surfaces and other measures.  Students will need to install QGIS on their own computers prior to the session.  QGIS may be downloaded from www.qgis.org.  Students should install the Long Term Release (LTR) version 3.10.x. 

Finding the Best Location using QGIS, September 14: https://libcal.princeton.edu/event/7010834

GIS software allows the user to treat the Earth’s surface as a continuous array of numbers.  Images and raster datasets can be used to rank suitable locations, estimate change and display phenomena such as elevation, precipitation or temperature. The session uses land use, distance from streams and elevation to rank the relative suitability of different areas.  This ‘weighted overlay’ method is useful in a variety of contexts.  Students will need to install QGIS on their own computers prior to the session.  QGIS may be downloaded from www.qgis.org.  Students should install the Long Term Release (LTR) version 3.10.x. 

Using Tables and Maps together in QGIS, September 15: https://libcal.princeton.edu/event/7010869

US Census data can be integrated with GIS boundary files to analyze the spatial relationships of poverty, ethnicity, environmental risk, and other parameters. Hands-on examples will show how to find and download demographic data, how to combine the data with GIS files, and how to view the data in QGIS. The session will assist any GIS user who wants to include tabular data in a spatial analysis.  Students will need to install QGIS on their own computers prior to the session.  QGIS may be downloaded from www.qgis.org.  Students should install the Long Term Release (LTR) version 3.10.x. 

Making Maps and Presentations using QGIS, September 16: https://libcal.princeton.edu/event/7010872

Maps can be extremely effective in communicating knowledge about an area. QGIS has many tools and techniques to design maps. Hands-on exercises will show how to use map-making tools within the software, and introduce common cartographic techniques. The session will discuss how to design maps for a variety of presentation formats.  Students will need to install QGIS on their own computers prior to the session.  QGIS may be downloaded from www.qgis.org.  Students should install the Long Term Release (LTR) version 3.10.x. 

Supervised Image Classification using QGIS, September 17: https://libcal.princeton.edu/event/7010874

The Semi-Automatic Classification Plugin for QGIS has many tools to download satellite images, and to classify satellite images and air photos into land use and land cover categories.  This session will work with Landsat images of New Jersey to conduct a supervised land use/land cover classification.  Students will need to install QGIS on their own computers prior to the session.  QGIS may be downloaded from www.qgis.org.  Students should install the Long Term Release (LTR) version 3.10.x. 

Using Tools to Create Models in QGIS, September 21: https://libcal.princeton.edu/event/7010876

GIS users often want to run a process multiple times, changing the inputs, parameters or summaries generated. QGIS has many ways to help users automate processes. The exercises show users how to use graphic tools in the Processing window, how to run models iteratively, and how to extract commands for use in Python scripts.  Students will need to install QGIS on their own computers prior to the session.  QGIS may be downloaded from www.qgis.org.  Students should install the Long Term Release (LTR) version 3.10.x. 

Essential QGIS Tools for Research, September 22: https://libcal.princeton.edu/event/7010879

In this class students will learn how to use GIS tools to calculate distances between two features, road and river lengths within administrative units, the percentage of shared boundaries between two areas, extract information on polygon neighbors between two areas, and will explore many other analysis tools.  Students will need to install QGIS on their own computers prior to the session.  QGIS may be downloaded from www.qgis.org.  Students should install the Long Term Release (LTR) version 3.10.x. 

Introduction to ArcGIS Pro, September 23: https://libcal.princeton.edu/event/7010880

A Geographic Information System (GIS) combines software and digital geographic data to generate maps, tables and interactive analyses of spatial information. Princeton faculty, students and staff use GIS technology to manage resources, explore spatial relationships, and visualize change. The class, intended for those with no previous GIS experience, describes the technology and includes simple exercises to introduce its capabilities.
