The advantage of digital over photographic imaging is evident: the resulting numerical data are precisely known, and digital data are not subject to the vagaries of difficult-to-control chemical processing with digital processing, it is possible to combine a large number of spectral images. The acquisition of the first multispectral digital data set from, the multispectral scanner (MSS) aboard the satellite Landsat in 1972 consequently attracted the attention of the entire geologic community. Landsat MSS data are now being applied to a variety of geologic problems that are difficult to solve by conventional methods alone. These include specific problems in mineral and energy resource exploration and the charting of glaciers and shallow seas. A more fundamental application of remote sensing is to augment conventional methods for geologic mapping of large areas. Regional maps present compositional structural and chronological information for reconstructing geologic revolution. Such reconstructions have important practical applications because the conditions under which rock units and other structural features are formed influence the occurrence of ore and petroleum deposits and affect the thickness and integrity of the geologic media in which the deposits are found. Geologic maps incorporate a large, varied body of specific field and laboratory measurements, but the maps must be interpretative because field measurements are always limited by rock exposure, accessibility and labor resources. With remote-sensing techniques, it is possible to obtain much geologic information more efficiently than it can be obtained on the ground. These techniques also facilitate overall interpretation. Since detailed geologic mapping is generally conducted in small areas, the continuity of regional features that had intermittent and variable expressions is often not recognized, but in the comprehensive views of Landsat images these continuities are apparent. However, some critical information cannot be obtained through remote sensing, and several characteristics of the Landsat MSS impose limitations on the acquisition of diagnostic data. Some of these limitations can be overcome by designing satellite systems especially for geologic purposes; but to be most effective, remote sensing data must still be combined with data from field surveys, laboratory tests, and the techniques of the earlier twentieth century.

The term "remote sensing" refers to the techniques of measurement and interpretation of phenomena from a distance. Prior to the mid-1960s the interpretation of film images was the primary means for remote sensing of the earth's geologic features. With the development of the optomechanical scanner, scientists began to construct digital multispectral images using data beyond the sensitivity range of visible light photography. These images are constructed by mechanically aligning pictorial representations of such phenomena as the reflection of light waves outside th

Just how tough the lobbying job on Capitol Hill will be become clear on Apr. 20, when Rubin lectured 19chief executives on the need to discipline their Republican allies. With business and the White House still trading charges over who is responsible for the defeat of fast-track trade negotiating legislation in 1997, working together won't be easy. And Republicans-with a wink-say that they'll eventually embrace China's entry into the WTO as a favor to Corporate Amenity. Though not long before they torture Clinton. But Zhu is out on a limb, and if Congress overdoes the criticism, he may be forced by domestic critics to renege. Business must make this much dear to both its GOP allies and the White House: This historic deal is too important to risk losing to any more partisan squabbling. 1.The main idea of this passage is( ) .2.It can be inferred from the passage that ( ).3.What does the sentence "Also left in the lurch: Wall Street, Hollywood, Detroit" convey?4.Who plays the leading part in the deal in America?5.What was the attitude of the Republican Party toward China's entry into the WTO?
A. Contradictory B. Appreciative C. Disapproving. D. Detestful.'>

President Clinton’s decision on Apr. 8 to send Chinese Premier Zhu Rongji packing without an agreement on China’s entry into the World Trade Organization seemed to be a massive miscalculation. The President took a drubbing from much of the press, which had breathlessly reported that a deal was in the bag. The Cabinet and White House still appeared divided, and business leaders were characterized as furious over the lost opportunity. Zhu charged that Clinton lacked ‘the courage” to reach an accord. And when Clinton later telephoned the angry Zhu to pledge a renewed effort at negotiations, the gesture was widely portrayed as a flip-flop.In fact, Clinton made the right decision in holding out for a better WTO deal. A lot more horse trading is needed before a final agreement can be reached. And without the Administration’s goal of a “bullet-proof agreement” that business lobbyists can enthusiastically sell to a Republican Congress, the whole process will end up in partisan acrimony that could harm relations with China for years.THE HARD PART. Many business lobbyists, while disappointed that the deal was not closed, agree that better terms can still be had. And Treasury, Secretary Robert E. Rubin, National Economic Council Director Gene B. Spelling, Commerce Secretary William M. Daley, and top trade negotiator Charlene Barshefsky all advised Clinton that while the Chinese had made a remarkable number of concessions, “we’re not there yet,’’ according to senior officials.Negotiating with Zhu over the remaining issues may be the easy part. Although Clinton can signal U.S. approval for China’s entry into the WTO himself, he needs Congress to grant Beijing permanent most-favored-nation status as part of a broad trade accord. And the temptation for meddling on Capital Hill may prove over-whelming. Zhu had barely landed before Senate Majority Leader Trent Lott (R-Miss) declared himself skeptical that China deserved entry into the WTO. And Senator Jesse
A. Helms (R-N C) and Ernest F. Hollings (D-S. C ) promised to introduce a bill requiring congressional approval of any deal.The hidden message from these three textile-state Southerners: Get more protection for the U S. c
