What this tracks
This dataset maps the boundaries and metadata of USGS topographic quadrangles (quads) covering Kansas.
Why it matters to you
These quads are the building blocks for land surveys, property boundaries, and historical land use records across Kansas. If you’re researching property history (like a farm’s past ownership) or planning outdoor activities (like hunting on public land), knowing which quad covers your area helps locate original survey maps. The QUADDATE field reveals whether your area’s map reflects recent changes or decades-old landscapes.
How to read this data
QUADNAME — The official name of the quadrangle (e.g., “Guymon”), often matching a prominent local feature or town.
QUADDATE — The year the quad’s map was published (e.g., 1979), indicating how current the geographic features are.
BOTTOM/TOP_/LEFT_/RIGHT_ — The latitude and longitude boundaries (e.g., 36.5 to 37°N, -102 to -101°W) showing the quad’s exact coverage area.
