Introduction to Mapping, Spatial Data and GIS

Overview

Investigate the power of maps and spatial data to document and illustrate local and global issues. Learn how to use Geographic Information Systems (GIS) to explore the world around you and share ideas. This IRES course will help participants apply GIS principles and tools to create your own maps from freely available online spatial data.

Discover the diverse uses of mapping, Geographic Information Systems (GIS) and spatial data, and how they underpin decision-making in every aspect of our lives. Explore and critically appraise maps to gain a better appreciation of the world around you. Learn how to use free open-source software (Quantum GIS) to import, display and analyze spatial data. Collect and integrate spatial data from a variety of sources. Experience realistic tasks in the context of international case studies, which range from resource management, wildlife conservation and leisure hiking to archaeology and disaster relief. Apply your learning to create maps, which illustrate your own interests or hobbies, based on sound cartographic principles.

Module 1: What are spatial data and Geographic Information Systems?

In this module, you will explore how maps and spatial analysis pervade our world and consider the use of maps in the media. Install the GIS software and take your first steps in displaying spatial data.

Module 2: Who uses spatial data, maps, and GIS, and what for?

Consider how GIS is used in different industries and leisure activities. Encounter the power and versatility of maps and GIS to illustrate patterns e.g. exploring osprey migration routes in a wildlife case study.

Module 3. Understanding spatial reference systems

In this module, you will learn how to refer to the spatial location of objects on the earth’s surface and understand how this translates to locations on a flat map. View and overlay data from a range of spatial reference systems, based on a case study.

Module 4. Representing spatial features

Grasp the difference between discrete spatial objects and continuous surfaces, and learn the characteristics of the two primary data formats (vector and raster) which represent them. Practice working with both data types in a case study.

Module 5. Interpreting Maps

Interpret the symbols, contours, and scale on a topographic map, and learn how to navigate using a compass.

Module 6. Working with Raster Layers

Experience the power of remotely sensed imagery to visualize environmental patterns. Manipulate raster layers e.g. in a disaster relief case study.

Module 7. Working with vector layers

Generate and edit your own vector data by hand- digitizing, and add non-geographic information to your new layers.

Module 8. Introduction to Symbology and Cartography

Explore the art of cartography, and discuss how to communicate your message to a specific audience. Change the way map features are displayed to identify spatial patterns.

Module 9. Making Maps

Learn how the key elements of a map (scale bar, legend, graticule) allow viewers to interpret your map and understand your message. Apply cartographic principles in a case study to create and export your own map.

Module 10. Introduction to spatial analysis

Discover how the utility of GIS extends far beyond map-making. Explore concepts in spatial analysis that will allow you to create new data, identify patterns, and support future decision-making.
