can can add contour lines to a raster-based surface in your map
to create a contour or topographic map. You add contour lines to
surface layers in Display Manager.
With contour lines, each
line connects points of equal elevation on the surface. The lines
can help you determine the elevation at a specific location on the
surface, help clarify and analyze the 3D surface terrain, and help
with things like navigation.
Contour lines added
to a DEM surface
Contour lines are stored
as new polyline or polygon features in an SDF file, and as a new
layer in Display Manager.
You can edit and style
the contour lines as you do any other feature layer. You can also
delete contour lines and recreate them.
When you add contour
lines, you specify the following:
- Name of the new contour layer
- Contour elevation interval
- Units (meters or feet) used to measure
- Major contour interval
- Contour labels
- Whether to create contours as polylines
- File name of the SDF that will store
the contour features
