Mapping, GIS, and Remote Sensing

A guide to mapping resources, including GIS (geographic information systems), at the UNT Libraries and on the Internet. The guide also provides links to geospatial and other data that can be downloaded and mapped.

What is GIS?

GIS = Geographic Information Systems
GIS is a collection of software, data, and people that supports mapping, analysis and decision making. GIS enables you to interact with data spatially in ways that tables, charts and static maps cannot achieve. For further reading, check out Penn State's open GIS textbook: The Nature of Geographic Information.

Here are some examples of what GIS can do:

  • Determine trends in desertification of an area based on rainfall data, soil samples and infrared signatures captured by satellites/aerial imagery. An additional step would be to predict relative health of plants or crops.
  • Determine from flood and traffic density data the best routes for hurricane evacuation from a coastal town.
  • Discover book publishing patterns in the British Isles during the Middle Ages using publisher data from catalogs and archives.
  • Model how an epidemic might spread through a population.
  • Predict the best location for a business based upon demographic data and trends in related businesses for the area of interest (image below shows a proposed gym location overlaid with distance/drive times and patrons (the color-coded points) that attend the two existing gym locations).

Introduction to GIS (webinar)

This webinar, hosted by Dr. Pinliang Dong from UNT's Department of Geography & the Environment, offers an introduction to GIS.
