Captured by Landsat 1, the first satellite of the US’s Landsat program, in the early 1970s at a scale of 1:500,000 (1 cm equals 5 km), these satellite images of Florida were superimposed with a Mercator grid, printed onto oversized poster panels, and then—likely decades later—scanned and digitized in ultra high-resolution. The resulting images, showing map keys, data, poster edges, creases and tears, paper textures, and grid lines, are accidentally psychedelic and purposefully very cool.
From 570 miles above the peninsula, these images were recorded in “discrete spectral bands” with a “Multispectral Scanner” which creates a wild, surreal, and otherworldly effect.

As seen in the detail above, a particular iteration of these archival images features four large posters, each measuring 57 by 42 inches, a kind of quadriptych by something called EXPERIMENTAL PRINTING (their words not ours).

Another iteration of these archival satellite images focuses exclusively on the Florida Keys.
The detail of the Florida Bay and the actual key islands, with psychedelic false-color reds vibrating against neon blue waves and wizard-white speckled clouds, seems to dance around the ancient paper as well as in our minds. I bet these posters smell like old books, too.
Imagery controlled to photoidentified ground positions. The root-mean-square error in position of well-defined features in relation to the grid is estimated to be 200 meters
