Some Definitions
• Photography: The art or process of producing images on a sensitized surface by the action of light or other radiant energy
• Image: A reproduction or imitation of the form of a view of objects
• Photo interpretation: The act of examining aerial photographs/images for the purpose of identifying objects and judging their significance
• Photogrammetry: The science or art of obtaining reliable measurements by means of photography

1858 Photography takes to the air
• 1858 - Gasper Felix Tournachon "Nadar" takes the first aerial photograph from a captive balloon from an altitude of 1,200 feet over Paris

Origins of Photogrammetry
• 1887 - Germans began experiments with aerial photographs and photogrammetric techniques for measuring features and areas in forests
• 1889 - Arthur Batut take the first aerial photograph from using a kite of Labruguiere France

Photo Interpretation Tasks• Detection and identification of features, phenomena, or
processes– Detection and interpretation– Labeling– Confidence assessment
• Measurement and estimation• Use in topographic and special purpose mapping• Map update• Problem solving
– Object complexes– Object relations– Assessments/causes
• Rating of evidence– Assembly of information– Ranking and assessment
