技术上相当复杂的新型土地卫星４号（Ｌａｎｄｓａｔ４）／主题绘图仪（ＴＭ—Ｔｈｅ－ｍａｔｉｃＭａｐｐｅｒ）土地观测卫星遥感系统，已经在提供簇新的而且很重要的红外线短波数据，这些数据与土地卫星多光谱扫描仪（ＭＳＳ）的可见光（ＶＩＳ）数据、甚远红外（ＶＮＩＲ）数据及热红外（ＴＩ）数据结合，将使全球规模的区域地质填图大为改善。主题绘图仪将明显改善世界上大面积分布的，粘土、氧化铁、铝土矿和镍红土的勘查填图能力。它还将改善对于与红土环境有关的重点植物的识别能力及确定其分布的能力。本文举例说明遥感技术在镍红土和铝红土方面的实际应用。印度尼西亚加格岛上的镍红土是通过多光谱扫描仪相片确定的，澳大利亚的韦帕、布干维尔角和达令地区铝土矿的卫星象图均显示出多光谱扫描仪数据用于铝土矿勘探和开采方面的潜力。牙买加和印度尼西亚西加里曼丹应用卫星和航空合成孔径雷达（ＳＡＲ）的实例也证实该方法在勘查铝土矿方面的用途。主题绘图仪的数据将与法国的定位与跟踪卫星高度的空间分辨能力、体视数字化数据以及美国、日本、欧洲、加拿大的综合孔径雷达的数据相结合，以支援世界上与铝土矿及其它红土型矿床有关的后勤供应、矿山开发和环境事务。
The technically quite complex Landsat 4 / TM-The-matic Mapper land-based observing satellite remote sensing system is already providing new and important sets of infrared short-wave data, which are closely related to Landsat Multi-Spectra The combination of Visible (VIS) data, Far Infrared (VNIR) data and Thermal Infrared (TI) data from a Scanner (MSS) will greatly improve regional geological mapping on a global scale. Thematic plotters will significantly improve survey mapping capabilities of the world’s large area of clay, iron oxide, bauxite and nickel laterites. It will also improve the ability to recognize and determine the distribution of key plants in the lateritic environment. This article exemplifies the practical application of remote sensing technology in nickel laterite and laterite. Nickel laterites on the island of Gager, Indonesia, were identified by multispectral scanner photographs, and satellite images of Bauxite deposits in the islands of Weipa, Bougainville and Darling in Australia all showed multispectral scanner data for bauxite Potential for exploration and mining. Examples of applications of satellites and aerosynthetic aperture radars (SARs) in Jamaica and Indonesia and Kalimantan in Indonesia also confirm the use of this method in prospecting for bauxites. Thematic plotter data will be combined with data from France’s positioning and tracking satellite’s high spatial resolution, stereovision data and synthetic aperture radar data in the United States, Japan, Europe and Canada to support the world’s efforts to bauxite and other Laterite deposits related to logistical supplies, mine development and environmental matters.
