- Zoom in closer to the Blue Dot.
- Click on the Elev. Profile button, and then the Draw Polyline button. This will allow you to
visualize the elevation profile of a potential road segment so you can adequately plan for BMPs
and erosion control.
- Click on the road segment NW of the blue dot to add a vertex and proceed by dragging the line
along the road, adding vertices when you need to change directions. Double click to end the
road segment. Type a Project Name in the Elevation Profile window and click Report.
The elevation profile is automatically calculated for the delineated road segment. The interactive graph shows the altitude, distance from start, and percent slope along points in the profile. The Elevation Profile Report is generated and summarizes results of the analysis. This
information can be used as inputs for the waterbar and wing ditch spacing charts in the Texas Forestry BMP Handbook.
Use the Elevation Profile Report to answer the following question:
