for the development of remote sensing techniques from aircraft and
spacecraft for numerous government agencies and universities. The
project is conducted in cooperation with the Departments of Agriculture,
Interior and Navy.
The major objective of the overall program is to derive benefits
from the utilization of both aeronautical and space activities in the

agriculture and forestry.
A total of 26 cities v_ll _e overflown for the Geographic
A_plications Program_ USGS. Purposes of the census flights_ which

time of the day_ is to gather standardized data on urban areas and
correlating land usage with data gathered during the census.
Wray of USGS_ _ho describes the aircraft census flights as
"census contemporaneous" said T'We plan to relate data gathered from
these flights with statistical data to determine to what extend we
can detect urban changes from the air or space."
The census flight experiment will provide interurban comparisons
of area_ functional and environmental characteristics of selected cities_
Wray said. This information will be used in evaluating the real ti_
television imagery which will be transmitted from the earth resources
technology satellite (ERTS) _hich is now scheduled to be launched
during
