Maps & research
Seeing the ground clearly
Space is evidence. We use ArcGIS to map displacement, food access, and change over time — and pair every map with the research that explains it.
The overlay
One ground, three layers
A map is built in layers registered to one ground. Here there are three: the story layer, where the work is read; the data layer, where it is counted; and the source layer beneath them both, where every line is footnoted. Select a layer to lift it from the stack.
Registration
Every layer lines up with the same ground
In a map, layers only mean something because they register: a story about a block sits over the parcels of that block, which sit over the record of who held them and how it changed hands. The three layers here register the same way. The StoryMaps quote the studies; the live map draws from the same records; the library is where both are footnoted, so a claim made in one can be checked in another.
Built on ArcGIS — StoryMaps, the Maps SDK for JavaScript, Dashboards, Experience Builder, Survey123 — each takes its place here as it is published. Where a layer is still in production, this page says so.
