Here’s a description of the steps involved in creating a topographic profile. This is not at all difficult in ArcGIS, though it can take a little hunting to find the necessary tools. Topographic profile created from ArcMap's 3D Analyst Often we are asked how to use a digital elevation model (DEM), or other raster image, to create a topographic profile graph, showing elevation as a function of distance along the profile route. Works with ArcGIS 10, not tested with Service Pack 1. The documents were created for an older version of the tool and have not been updated. The output layers are automatically symbolized and labeled in a new data frame. The user can choose which outputs he or she wants. A button control launches a form that obtains the required inputs. The program will convert between feet and meters, depending on the units of the input data. The user defines a sampling interval and vertical exaggeration.
The user provides input data: lines of cross section, an elevation raster, geology polygons, well points, and a table with subsurface data. Visual Basic for Applications (VBA) was used to develop the program. You can download this free tool in ZIP file contains an.mxd, user guide, tutorial instructions (tutorial data not included).
