Understanding The Need For Usgs Aerial Photography

USGS stands for United States Geological Survey. This organization keeps different photos and images taken from the air. They have archives of information in the Earth Science Information Center. These USGS aerial photography and images are taken by satellite. The availability of data pertaining to the images can be obtained from different state and government establishments. Also, one can go on the internet to www.usgs.gov.SatelliteImagery.

Different agencies have been trying to take pictures of the earth from aerial views since way back in the 1800’s. In those days cameras were mounted on kites or balloons—this method did not produce very clean pictures but it was all they had over time. Modern technology has allowed more precise and detailed photography and satellite images. It is of extreme importance and benefit for these pictures and also maps to be taken from an aerial view because of the multiple uses—for scientists, environmental experts, surveyors, planners, people looking for boundaries, and even people attempting to use them for historical reasons.

USGS aerial photography can show the outline of hiking trails, roads and their destinations, and can pinpoint areas in which to hunt and explore a land filled with the overgrowth of the mountains and forests. It can keep a person from losing themselves in this wide open terrain called earth—this clear topography can direct the engineers and surveyors of the land and help them to see places that they never even knew existed.

Another resource of USGS aerial photography products and information is the National Land Remote

Sensing Data Archive. Here there are almost 50 million images taken by satellite and about 8 million photographs of the country (USA) taken from the air.

Aerial pictures are taken every few years in order to keep an update on geographical changes in the surface of the land and growth on the land. Historians and geographical experts can take different USGS aerial photography and match it against photographs from another time era. It is interesting and informative to see the changes that time and technology force on the landscape and the way people live.

These aerial images can be purchased as gifts for friends, they can be ordered in map form and framed for your own use. You can have information mailed to you by contacting the National Archives and Records Administration in College Park, MD.
