Development
The use of geophysical survey is well established in European archaeology, especially in Great Britain, where it was pioneered in the 1940s and 1950s. It is increasingly employed in other parts of the world, and with increasing success as techniques are adapted to unique regional conditions.
In early surveys, measurements were recorded individually and plotted by hand. Although useful results were sometimes obtained, practical applications were limited by the enormous amount of labor required. Data processing was minimal and sample densities were necessarily low.
Although the sensitivity of sensors has improved, and new methods have been developed, the most important developments have been automated data logging and computers to handle and process large amounts of data. Continuing improvements in survey equipment performance and automation have made it possible to rapidly survey large areas. Rapid data collection has also made it practical to achieve the high sample densities necessary to resolve small or subtle features. Advances in processing and imaging software have made it possible to detect, display, and interpret subtle archaeological patterning within the geophysical data.

Famous quotes containing the word development:
“The development of civilization and industry in general has always shown itself so active in the destruction of forests that everything that has been done for their conservation and production is completely insignificant in comparison.”
—Karl Marx (1818–1883)
“Creativity seems to emerge from multiple experiences, coupled with a well-supported development of personal resources, including a sense of freedom to venture beyond the known.”
—Loris Malaguzzi (20th century)
“... work is only part of a man’s life; play, family, church, individual and group contacts, educational opportunities, the intelligent exercise of citizenship, all play a part in a well-rounded life. Workers are men and women with potentialities for mental and spiritual development as well as for physical health. We are paying the price today of having too long sidestepped all that this means to the mental, moral, and spiritual health of our nation.”
—Mary Barnett Gilson (1877–?)
