  • We can make maps to advocate for issues we care about in our communities, like environmental justice. But to do this, we also need to become good readers of maps.

# Looking ahead to Session 2

In the next session, we will

  • Dive deeper into different types of data,
  • Introduce projections,
  • Go over the concept of joining spatial and non-spatial data,
  • Review the different file types you might encounter when making a map, and
  • Have a closer look at the LMEC Public Data Portal.
