The shape of the world pops out easily from laser data because they represent a direct contour map of the surrounding area.

这些雷达资料，能够轻轻松松地产出环境世界的形貌，是因为他们直接将周遭环境用等高线地图呈现出来；一台相机先间接捕捉了环境型态的几何资讯。

And then, the contour plot will be the topographical map for this graph.

等高线就像是这幅图的地形图。

In this paper, the methods of drawing contour line from terrain map, the vector of contour line and generating elevation data from vector data are discussed.

论述了从地形图中提取等高线、对等高线矢量化以及通过矢量数据生成高程数据的实现方法。

Each missile comes with a terrain contour matching radar, which compares a stored map reference with the actual terrain to fix the missile's position.

BaseCamp displays topographic map data in 2-D or 3-D on their computer screen, including contour lines and elevation profiles.
