MAKE THE LAYER
MEAN SOMETHING.

4 field guides for a clearer view of city data.

A city layer needs more than coordinates. It needs stable identifiers, clear attributes, source notes, and a definition of what an unknown value means. The guides here explore those foundations alongside source-aware map reading, historical labels, and reviewable AI interpretation. Together they help turn a collection of features into information another person can inspect.

Begin with the city mapping workflow for a structured neighborhood example. Use the map-reading guide to test the visual explanation and the vintage article when older sources enter the project. The AI guide adds a way to preserve original material while reviewing suggestions. Keep the collection’s purpose and coverage visible: a cluster of recorded points may reflect the way the data was gathered rather than a complete picture of the city or a verified absence elsewhere.
