"Flea Market Mapping"
summary
Buys old city maps at flea markets, scans them, and georectifies them so they align with modern slippy maps; tools are a flatbed scanner, Photoshop, getlon.com for picking coordinates and a geodata library dubbed jll or Gall to warp images via rubber sheeting. Shows 1877, 1912, 1936 and 1967 Oakland maps, plus LA, Berlin and Olympic-site aerials, produces tiled georectified maps that let users pan/zoom and page back through time — the workflow works and yields a browsable historical layer.
