Definition: Black and white photos
Land Use/Land Cover
The film emulsion of black and white photos is adjusted slightly from regular film.
The first reliable black and white film was developed at the beginning of the century. With the aeronautical development the age of aerial photography was initiated. Due to a long tradition, national mapping agencies dispose of huge historic archives of aerial photographs, which reveal details in the changes of the landscape.
