Geographic Information Systems (GIS) is the combination of geospatial software (e.g., ArcGIS), tools (e.g., a GPS receiver), and geospatial data. While GIS is a form of data visualization, it also falls under the category of mapping. In the examples below, you can see how GIS can be used for visualizing all kinds of data including statistics and geographic areas. GIS is used for creating both static maps, such as the kind one sees in presentations and books, and interactive maps that can be shared online.

Traditional GIS Maps

This presentation poster created for the 2019 BC Libraries GIS contest has maps created in ArcGIS (see more information about the project in BC's eScholarship).

Interactive GIS Maps

This interactive map was created in Leaflet using curated spatial data of Gabii, an archaeological site outside of Rome.
Created by Matt Naglak, BC Digital Scholarship Librarian
The map's interactive nature allows users to click on individual features to find out more about them as well as perform actions such as take measurements, search by feature number, and turn on and off different years of aerial imagery to see how the excavation evolved.
