Contour lines are a familiar way of representing surfaces on maps. A contour is a line through all contiguous points with equal height (or other) values.
You can create contour lines for a raster, triangulated irregular network (TIN), or terrain dataset surface. You can use the following geoprocessing tools to create contours from a surface.
Creating contour lines from a raster surface
- To create contours or isolines from a raster surface, use the Contour tool.
- To create contours or isolines based on a list of contour values, use the Contour List tool.
- To create contours from a raster surface and independently generate contours on either side of a barrier, use the Contour With Barriers tool.
Creating contour lines from a TIN or terrain dataset surface
- To create contours or isolines from a TIN or terrain dataset surface, use the Surface Contour tool.
