在ArcGIS 10中计算折线的高程轮廓？

我的海拔数据是浮点tif。我有一条需要计算高程剖面的道路，但看不到用于执行此操作的工具。

我可以使用带有空间分析器/ 3D分析器的ArcGIS来执行此操作吗？

如何从曲面的数字化特征创建轮廓图

1.In ArcMap, click the Layer drop-down arrow on the 3D Analyst toolbar and click the 
surface that you want to profile.

2.Click the Interpolate Line button Interpolate Line button.

3.Click the surface and digitize a line you want to profile. When you are finished added
vertices to the line, double-click to stop digitizing.

4.Click the Create Profile Graph button profile graph button.

5.Optionally, you can change the layout of the profile graph, right-click the title bar
of the profile graph and click Properties. Change the basic layout options and click
OK, or click Advanced Options to make more complex changes to the layout. 

如何从3D线特征创建轮廓图

1.In ArcMap, ensure that the layer containing the 3D line feautes you wish to profile
are checked as visible in the table of contents.

2.Click the Select Features tool from the Tools toolbar.

3.Click the 3D line feature or features you wish to profile.

NOTE: Use the shift key to select more than one graphic.

4.Click the Create Profile Graph button profile graph button from the 3D interactive 
toolbar. The profile graph appears as a floating window on your map.

下图所示的分析描述了沿道路的高程变化。

这也将帮助您在ArcGIS中创建地形轮廓。
