What is GIS, and why is it important?

GIS, or Geographical Information Systems, refers to tools we use to map, view, and analyze spatial data. By combining real-life data and the technology to visualize and organize this data, we are able to better understand the world around us. GIS allows us to:

  • Identify, prioritize, and address problems
  • Understand and forecast trends
  • Analyze relationships between populations and the environment

GIS is especially important when it comes to issues such as housing insecurity and homelessness - with maps we can better understand the impacts of redlining, redistricting, gerrymandering, and other practices that disproportionately affect communities with lesser access and privilege. Historically, the ability to create and dictate the geography of our communities through maps is held by those with power and means. However, with today's GIS - which is both user-friendly and accessible - it is easier than ever for communities to rebuild, replan, and change their environment to what most equitably serves them.
