The WMS Digitize Toolbar provides a quick way to create TIN vertices if there are known elevations and there is no source of accurate elevation data other than a digital map.
For example, if there is an image of a contour map with known contour elevations, turn on the Digitize Toolbar and then turn on Digitize Mode. Define an elevation value and then click on points along the contour to define vertices on a TIN, as shown below.
Once all the vertices have been defined on the TIN, turn off the digitize mode and triangulate the TIN to use the TIN in the hydrologic or hydraulic model.
