摘要
随着GIS技术引进地质领域,数字地质图全面取代了传统地质图。它克服了模拟地质图的缺欠,可快捷地实现投影变换、随意确定比例尺、任意选择显示范围、选取内容及内容的表达方式等,是今后地质成果的重要表现形式。
With GIS technique is introduced into geologic realm, the traditional geologic map is completely the digital geologic map. It overcomes all shortages of the simulated geologic map, and can quickly realize projection transformation, that can freely determine scale, freely choose displaying range, contents and its expression. It can be used as an important expression for the geologic results from now on.
