Traditionally, these photoâ€" graphs were used for weather forecasts, but they also reveal information about the land itself, show, for example, water areas of lakes, the spread of pollution and deforestation of land. Thus, they significantly imâ€" prove our capability of taking an inventory of natural resources. Huge, complex and very exâ€" pensive computers are required to receive, interpret and analyze the information provided by the satellites. This equipment (inâ€" cluding significant computer hardware) is beyond the means of many small, thirdâ€"world counâ€" tries . . . though they are the ones that could benefit most by being able to tell what‘s happening to their natural resources. The problem is, therefore, to develop methods that will enable satellite data to be handled by lowâ€"cost miniâ€"computers, which virtually every country in the world can afford. Prof. Shully Solomon, a civil engineer at the University of Waterloo, together with B. J. Swain, Shawinigan Engineering Co., Quebec, have done exactly that. Solomon became interested in this work when he himself was doing extensive research on renâ€" ewable resources of various types (including water and solar energy), for which he was using digital data (information transâ€" mitted in the form of numbers) obtained from Landsat and GOES satellites. He and Swain developed two sets of computer software proâ€" grams to display and interpret satellite data. Extensive tests have proved inexpensive equipâ€" ment can readily handle the inâ€" formation. Landsat satellites circle the earth at a height of about 900 kilometers. Every habitable reâ€" gion of the earth‘s surface is crossed by these satellites at least once every 18 days. Landsat forwards both digital data and pictures to receiving stations such as those of the Canadian Center for Remote Sensing or the EROS Data Center of Geological Survey in the United States. SATELLITE PHOTOGRAPHY Landsat data will show quite accurately how much water there is in a reservoir, or the extent of a flood after a storm. It will be particularly helpful in finding practical solutions to reâ€" gional planning problems â€" esâ€" pecially for mapping landâ€"use, landâ€"cover of areas. Solomon has made extensive use of Landsat in Columbia, South America, where he has produced such maps for a large part of the country. _ Solomon is especially pleased with the results of the GOES satellite applications.

These can be printed GOES data are used primarily for meteorological purposes, speâ€" cifically to determine the amount of cloud cover and sunshine received in a given area. But GOES can also be used for regional planning by determining rough landâ€"use and landâ€"cover. out in the form of computer plotted maps, and comparisons with cartographic maps demonâ€" strate how exact the GOES maps Solomon has a number of students involved in studying and testing various GOES related projects. For instance, one has investigated the possibility of mapping landâ€"use, landâ€"cover and deforestation using GOES data. Another is using GOES to investigate the hydrology (moveâ€" ment of water on, above and under land) of southern British Columbia. According to Solomon, the most important use of these new software programs could be made by thirdâ€"world countries with neither the funding nor the technology for large computer systems. He cites, as an example, a study of one of his students in Pakistan. This student used Landsat pictures to predict floodâ€" ing in Pakistan at the start of the rainy season. He was able to determine the amount of water that could be expected to enter the large reservoirs recently constructed in the Hindus River. This information enables the levels to be reduced in advance of flooding and prevent their rising beyond danger limits. Solomon says it is particularly advantagepus for Pakistan to be able to do this because in that country, at one time very dry, irrigation has been overdone. Thus, in some areas the land cannot absorb the large amounts of precipitation received during rainy seasons, and flooding creates many additional probâ€" lems such as waterlogging and salinization (the land becomes impregnated with salt). India has shown great interest in Solomon‘s research and he has been asked to go there and lecture on his new techniques. His work has received a good deal of attention in Canada as well. Recently it merited an award from the Association of Consulting Engineers of Canada. His research also receives fundâ€" ing and assistance from the World Meteorological Organizaâ€" tion (WMO). Future applications of GOES and Landsat software programs are probably unlimited â€" they need only to be conceived and deâ€" veloped .
