Geographic Information Systems

Mapping the environment

Every aspect of the Environmental Protection Agency’s (EPA) work is concerned with a location, whether it is an overall environmental assessment at a national scale for national reports or a smaller scale study of the local environment. Digital maps play a very important role in helping the EPA to assess the environment and monitor changes over time.

Geographic Information Systems (GIS) is the term used to describe the collection of the EPA's digital map data and the specialised software used to view these maps. The EPA has a small team of GIS experts who develop and enhance GIS datasets, and develop and support web mapping services.

Web Mapping Systems

To make GIS data accessible to the general public, the EPA has developed a number of public online mapping viewers. These can be accessed by going directly to the EPA Geoportal and selecting the Browse a Map link. National level data across the following themes can be mapped using public online mapping viewers:

  • Land and soil
  • Waste
  • Environment and Well-Being
  • Water
  • Nature
  • Sustainable Economy
