Intermediate Contour – An imaginary line on the ground joining points of equal elevation above the Australian Height Datum, showing increasing and decreasing elevation values at 1 metre intervals.
Index Contour – Being every fifth “Intermediate Contour” - classified as Feature Type “Index Contour”. The elevation values are divisible by 5.
Upper_scale:
1:10 000 – all Intermediate Contours
1:25 000 – all Index Contours
INTERMEDIATE CONTOUR
Definition: An imaginary line on the ground joining points of equal elevation above the Australian Height Datum, showing increasing and decreasing elevation values at 1 metre intervals.
Alternate Terms: Basic Contour
Capture as a 2D polyline
Capture with a contour interval of 1 metre
Auto-generate from a digital terrain model captured using LiDAR technology.
