| Interpolates contours from a
raster. The contours can be created as PolylineZs with constant Z values
representing the elevation.
Inputs:
- A raster dataset.
- Base value - the contour from which to
begin generation of contours.
- Contour interval - Z value difference
between adjacent contours in map units.
- Option for interpolating 3D contours.
- Option for smoothing the contours.
Outputs:
- New polyline feature class. If the
option for creating 3D contours is used the output will be PolylineZ
feature class.
- A new field ET_Height is added to the
attribute table. The values of this field contain the Z value for each
contour.
Notes:
- The smooth polylines option might be time
consuming.
- The input raster must have a projected
coordinate system.
