用等高线表示地面起伏和高度状况的地图。在同一幅等高线地形图上,地面越高,等高线条数越多。等高线密集的地方,地面坡度陡峻。凡等高线重合处,必为峭壁。若等高线成较小的封闭曲线时,这一地区便是山峰、洼地或小岛。等高线的形状是从山顶起逐渐向外凸出的为山脊,山脊的连线称为分水线。等高线形状逐渐向山顶或鞍部方向凹八的为山谷,谷地的连线私:为集水线。两条等高线凸侧互相对称处,称为山的鞍部。
我有等高线地形图,但是我想删除其中白色背景并且把等高线变白,代替以前的黑色。
I have topography line work but I want to remove the white background and I also want the line work to be white, not black.
给出了平面等高线地形图,带地物符号的工程地形图,立体等高线图及逼真地形图等多种造型方法。
And various methods of modelling, that is, contour maps, engineering maps with surface feature symbols, 3 D contours and realistic maps are given.
等高线就像是这幅图的地形图。
And then, the contour plot will be the topographical map for this graph.
