Map Making in the Good Old Days

If you have been making maps for a long time, then you remember ink on mylar, Leroy lettering sets, and adhesive-backed screentones like Zip-A-Tone and Letraset.

Mapping Indigenous LA

The Mapping Indigenous Los Angeles project from the University of California Los Angeles is creating a series of story maps that bring together a variety of stakeholders to help highlight “multiple layers” of diversity and identity.  At the heart of the site are the story maps themselves, which unfold to reveal the complex history of place and the Indigenous peoples who have helped shape and been shaped by them.  The story maps vary in length and depth, but all feature a variety of text, photos, podcasts, and other materials that help viewers immerse themselves in the subject matter and deepen their understanding.  Check it out!
