基于等高线地形图的地形特征的计算机自动识别技术在国内外都处于初步发展阶段。

The computer discovery technology of terrain features in topographic map is a new research project at home and abroad .

要实现从原有二维的仅仅只带等高线的地形图到三维模型的转换还需要将CAD文件数字化，最后通过多次转换实现。

To achieve just only from the original two-dimensional topographic map with contour lines into three-dimensional model of the conversion will also need to digital CAD files , and finally achieved through several conversion .

以上数据在计算机上都以二维平面图的方式体现，尽管拥有标注等高线的地形图，给专业人员描绘出抽象的地形三维形态，但一般人员普遍感觉直观性差、难以判读。

The data mentioned above is reflected as two-dimensional floor plan on the computer . Although the topographic maps with marking contour depict the abstract three-dimensional ( 3-D ) shape of the terrain to the professional , the general staff normally feel the visual differences and difficulties to read .
