The HSLNTYPE attribute contains a one-digit code attribute value to
identify the specific type of the contour line. These lines supplement
those in the HYAREA.AFT but do not form complete polygons.
ONC Codes
1 = Partial intermediate or
auxiliary contour
403.1
2
=
Partial depression contour
403.4
3
=
Partial approximate intermediate
403.2
or auxiliary contour
403.3
4
=
"Carrying contour"
5
=
Cut within one contour interval
411.1
Fill within one contour interval
411.3
6
=
Unreliable - JNC data only
7
=
Transition contour (FIGURE 5)
8
=
Partial approximate depression contour
HSLNVAL
The HSLNVAL attribute contains the elevation value in feet above MSL of
the supplemental contour line. The code 99999 is used to indicate
elevation values that cannot be determined.
