WIMMERA Catchment Management Authority began its drone trial to improve flood planning on Tuesday.
Australian Unmanned Aerial Vehicle director James Rennie started flying a drone and taking photos of Horsham about 7am.
The authority hopes the drone technology can provide more detailed data than traditional survey methods.
The drones have the ability to record floor levels, record altitude measurements and topography data.
Mr Rennie said he was confident the trial would work.
“Just like with all new things it’s a little bit tricky,” he said.
Mr Rennie said the drone photos would help create a three-dimensional flood model of a specific area.
“We will use the data collected by the drone to simulate where water might flow through the flood model,” he said.
Mr Rennie said the cloudy conditions on Tuesday were perfect for the trial.
“Cloud means we don’t have shadows, shadows can sometimes cause a few issues and also reflection off buildings,” he said.
