HOW TO USE

1. Find the spot. Type an address, coordinates, State Plane X/Y or a parcel PIN — or press P and click a lot.
2. Pick years. Click a year for A, shift-click (or right-click) for B. Switch to Swipe or Fade to compare, or hit Space to flip through every year.
3. Set the area. D to drag a box, "Use view", a square around the center, or "Use parcel" from a parcel popup.
4. Download. Choose years, format and resolution. "Max" pulls each year at its native sharpness; large areas are fetched as tiles and stitched automatically. GeoTIFFs and world files drop straight into QGIS / ArcGIS.

Historic sets (1926–1968) are black-and-white scans; some years and the Parks / Sandy sets only cover part of the state — the timeline dims years with no imagery at your spot.
