At Budj Bim
Laser mapping technology used at the Budj Bim World Heritage site near Portland is revealing eel and fishtraps, and stone huts that have never been recorded before.
The technology, known as Light Detection and Ranging scans through thick scrub and bush to identify and map the terrain, revealing features not seen by the naked eye.
Denis Rose, from the Gunditj Mirring Traditional Owners Aboriginal Corporation, says recent data obtained has helped identify hidden groups of stone hut bases under vegetation and a 115-metre extension of a fish trap complex in the aquaculture system. The technology has helped expand the knowledge about one of the oldest and most extensive aquaculture systems in the world.“The laser mapping technology comes from aerial flyover, the plan flies over the Budj Bim cultural landscape, takes images. One vertically, one horizontally and one diagonally. And then those images are all put together in the computer and then we interpret the data from that.”
