The objective of this course introduces students to the fundamental skills required to create and interpret thematic maps—maps that focus on specific topics or types of information, such as population, rainfall, or land use. The emphasis is on clear and effective map design, enabling students to present geographic data visually in a meaningful and accurate way.Students will learn to use various types of diagrams—such as line, bar, and circle graphs—to represent data, along with mapping techniques like choropleth maps, dot maps, and proportional symbols to display spatial patterns based on area or point data. They will also explore the use of isolines to represent continuous phenomena such as temperature or elevation.The course further provides training in the use of overlays, combining different types of map data (points, lines, and areas) to better understand spatial relationships. Practical demonstrations are incorporated to familiarize students with open-source GIS platforms such as QGIS for preparing simple thematic maps. These hands-on sessions will equip students with the technical skills needed to apply thematic mapping techniques in their research projects and other academic or professional work.By the end of the course, students will be able to design and produce clear, effective thematic maps and will have a solid understanding of how geographic data can be visually communicated to reveal spatial patterns and relationships.
