—Lancaster Farming, Saturday, August 12, 1972 18 Penn Staters Use Satellite for Flood Study The “high-water mark” of the Great Flood of ‘72 may be known sooner than expected, if the NASA Earth Resources Technology Satellite (ERTS) launched recently from Van denberg Air Force Base does its job. Obtaining data on the flood was not programmed into the NASA package, but a group of Penn State scientists and engineers have been planning for two years to use the sensor satellite to get information on a particular portion of Penn sylvania. That portion happens to coincide with the heart of the flood-ravaged region: the SUBSCRIBE NOW We know many of our readers regularly read a friend’s or relative’s copy of our publication. We don’t mind. We ap preciate all our re Jers. But we wonder if everyone realizes how easy it is to receive our publication. On a yearly subscription in Lancaster County, the cost is less than four cents a week. Only $2.00 per year. On a two-year subscription in Lancaster County, it’s less than three cents a week. Only $3.00 for-two years. Because mailing rates are higher for out-of-county subscriptions, we have to charge more But out-of county readers can get the paper delivered every week for a yearly subscriptions which costs less than six cents a week and a two year sub scription for less than five cents a week. Only $3.00 for one year and $5.00 for two years. Think about it. In these times of high and rising costs, we’re sure you can’t find a better bargain anywhere Call us at 394-3047 or 626- 2191 Or write to Lancaster Farming,? 0 Box266,Lititz, Pa 17543 Contract with leading herds in the area, or Co-operate with universities and allied industires, Test equipment and facilities, or Build your own p'-ocedures, Test suppliers products to find the best, or Employ computers to digest a host of information?

The polar orbit of the satel lite will bring the payload optical and eletronic sensing cameras—over the Basin once every eighteen days. “If we’re lucky with the weather,” says Dr. George McMurtry, associate professor of electrical engineering, “we should be able to map the extent of the flood-plain from data ob tained on one pass of ERTS. This knowledge, along with data on ruined crops, sediment deposits, etc., should be extremely valuable to Pennsylvania and other affected states as they begin to plan for recovery.” McMurtry and Dr. Gary Petersen head a group of more than twenty Penn State scientists and engineers ready to begin interpreting data transmitted by the satellite, which is the first to be flown with the exclusive mission of collecting data on earth resources. The Penn State project is funded by a grant from NASA. “The areas that were flooded,” says Petersen, associate professor of soils, “are expected to be visibly in terms of altered reflectance; sediments left by flood waters will yield a different response than unaffected soils. Also, vegetation killed by the flood will likely reflect at dif ferent levels than living, healthy plants ” The intent of the NASA ex periment, in which several other universities and government agencies are participating, is to obtain a resource survey of the United States. Flights by photographic planes, some of which have already taken place, are included in the massive project Its purpose is to identify resources—and resource deterioration —by remote sen sing Lakes and rivers, strip mine terrain, acid-mine drainage, soil types, forests, oil slicks, fish migration, and ocean current behavior are some of the features to be studied. In effect, the project represents feed mill to test Trading as Good’s Feed Mill Specializing in DAIRY & HOG FEEDS New Providence, Pa. Phone 786-2500 manufacturing the first stage in the compilation of a “whole-earth catalogue,” a basic reference manual showing the pattern each known resource yields when viewed from space. Information obtained from the remotely sensed data will be made available to state agencies such as the Department of En vironmental Resources and the Department of Transportation, and to Federal agencies such as the U.S. Army Corps of Engineers and U.S. Department of the Interior. This information can then be used for resource inventory, land use analysis, and planning purposes. The Penn State team awaiting data from ERTS is one of the largest and most diverse groups ever assembled at the University for a single research project; it includes geophysicists, hydrologists, foresters, meteorologists, agricultural economists, planning experts, geologists, civil and electrical engineers, plant pathologists and several experts in photo interpretation. This group is called the Office for Remote Sensing of Earth Resources (ORSER) a division of the University’s Space Science and Engineering Laboratory, headed by Paul Ebaugh, associate dean of engineering. The Penn State group will be sent data from NASA receiving stations in the form of both op tical and digital read-out. The data will be processed at the Penn State Computation Center and the scientists will then begin earth’s resources, and one of its studying it in an effort to extend greatest disasters, look when their understanding of how the remotely sensed.
