Mapping Climate Change with GIS Analysis

Mapping Climate Change with GIS Analysis is a short course by Geograf.io Learn that provides an overview of performing sea level change analysis using the free and open source QGIS software platform. Participants will use GIS research methods to identify coastal areas that will potentially be inundated as a result of sea level change associated with anthropogenic climate change. More specifically, participants will learn to (1) obtain high-resolution digital elevation models (DEMs), (2) use raster analysis and map algebra techniques to estimate sea level change scenarios, and (3) create user-friendly maps of these scenarios with the mapping features provided by QGIS.

Interrogating GIS Data: Selections and SQL Queries

Interrogating GIS Data: Selections and SQL Queries is a short course by Geograf.io Learn that provides an overview of performing manual, spatial, and attribute queries and selections using the free and open source QGIS desktop GIS software platform. Participants will use Specifically, participants will learn to (1) manually select features using interactive selection tools, (2) save selected features as separate vector data files, (3) use structured query language (SQL) expressions to select features on the basis of attribute values, and (3) select features on the basis of spatial relationships with features in other layers.

Thematic Mapping with QGIS: Mapping Election Data

Thematic Mapping with QGIS is a short course by Geograf.io Learn that provides an overview of creating many forms of thematic maps with QGIS. In contrast to reference maps, which are primarily created to display the locations of geographic features, thematic maps are any maps that are designed to display specific themes, topics, or phenomena that occur spatially. Several thematic mapping techniques are introduced, including (1) choropleth mapping of qualitative and quantitative data, (2) graduated symbol mapping, (3) diagram mapping, and (4) dot density mapping.
