Profile graphs allow the visualization of elevation changes across 3D transects. With an elevation layer such as a digital elevation model (DEM), it is possible to create profile graphs from line features that initially do not possess z-values. Studying elevation changes across line features is helpful in assessing the topography of a desired area before seeking to build dams, roads, or railways.
The image below shows 11 major fault zones across Los Angeles that constitute potential sites for earthquakes. The fault zones are represented as line features with no z-values. The major fault layer is underlain by a DEM layer containing elevation data. In this example, a profile graph of the major fault lines is created.
A profile graph is created from line features without z-values in ArcGIS Pro using the Interpolate Shape tool and the Profile Graph function. Follow the steps below:
A new line feature layer containing line features with interpolated z-values is created.
Note: This function requires the 3D Analyst license.
The following image shows a profile graph of the 11 major fault lines.
Note: • A maximum of 20 lines are graphed at a time. • To analyze a single line, select the desired line, and click Selection.
