So I am trying to create a workbench that will take a 3D Polyline and drape the vertices based on the USGS 10m NED data. I would like for the data to be queried based on the 3D Polyline which will be projected into a UTM Zone based on US Survey Feet. The thought of using an HTTPCaller has been suggested, however I am not quite sure on the steps to take to ensure the query is accurate.
Has anyone achieved this?
