2. Outlines  Remote Sensing  Early Aerial Photography  Bavarian Pigeon Corps  Baloon Observations  Kites Observations  Advancement in Photography  Fill Roll  Mounting Camera on Aircraft  Aerial Image Analysis  Satellite Remote Sensing

3. Remote Sensing  Acquiring information about an object without being in physical contact with that object.  Remote Sensing is the science and art of obtaining information about an object, area or phenomena through the analysis of data acquired by a devise that is not in contact with the object. (Lillisand, 2007)

4. Remote Sensing  Remote sensing is defined as the science of  Acquiring  Processing  Interpreting  Images and related data, obtained from aircraft and satellite that record the interaction between metter and electromagnetic radiations. (Floyd, 1999)

5. 5  To gain overview of an area  To gather information on large areas in short time  To gather information cost-effectively  To gather information on inaccessible places  To replace conventional sources of information (topo-sheets, census data etc.) Why Remote Sensing?

11. Early aerial photographs  Gaspard Tournachon (aka Nadar) 1859 – Balloon photos for land surveys  These early photos mainly served as novelties and curiosities;  Inability to control altitude and flight path presented obstacles. NARA

12. Bavarian Pigeon Corps (1903)

13. San Francisco, 1906 NARA LIBRARY OF CONGRESS CHICACO HISTORICAL SOCETY George Lawrence developed a system to use multiple kites to fly a panoramic camera

14. Roll Film  George Eastman (1854-1932), transformed photography from an expensive hobby to an inexpensive and immensely popular pastime.  1884: Eastman patented the first practical roll film.  1888: He perfected the Kodak camera, designed specifically for roll film.  1892: He established the Eastman Kodak Company, one of the first firms to mass- produce standardized photography equipment.

15. Early Airplane Photography (1909) The camera and the airplane were not designed to be used with each other– an uneasy partnership for a long time.

16. First conflict to focus upon mechanized weaponry; Fixed lines across the western front- conventional reconnaissance blinded; Artillery became the principal combat arm; Aviation in its infancy; Photography still in its youth; Aviation and photography not integrated. World War I Incubator of aerial photography

17. Balloon Observation

18. 1. Infantry liaison; 2. Artillery rélage; 3. Aerial observation and photography. Aerial observation and photography soon became the primary foci, with increasing significance assigned to the photographic mission. Aerial Observation Missions

19. Aerial observers were trained to report against a detailed checklist; photography was ancillary to the observation mission.
