A derived aerial image looking down over a section of land with contour lines representing the contour of the landscape.

- ALS-derived DEM with 50 cm contours.

A LiDAR colourised image looking diagonally down at a cross-section of terrain. The image shows a section of cliffs along the Victorian coast, with blue water and waves. A circular road cuts through the landscape above the cliffs, and different textures of shrub and grass cover the terrain.

- RGB colourised ALS LiDAR.

A computer screen shows two windows. The main window shows a derived image centred on a rural road at night, with tall trees flanking the road. The second tall and window to the left of the screen shows an aerial view of the same section of road, with the area in view from the main window colourised to show heights. Shades of deep blue depict the lowest heights towards the bottom end of the image, through to shades of red for the highest points of the trees at the top end of the image.

- MLS from road view showing derived road centre and edge lines.

In 2019-20, the entire Great Ocean Road was mapped using both aerial and mobile LiDAR (ALS/MLS), as well as high-resolution aerial imagery.

This project enabled Surveyor-General Victoria (SGV) to improve the mapping of properties and parcels along the road and deliver a major priority of the Great Ocean Road Action Plan. It helped establish the Great Ocean Road Coast and Parks Authority (GORCAPA) and to protect and manage coastal Crown land along the Great Ocean Road.
