Capturing our changing coastline from above

Since 1974, the Coastal Oblique Photography Monitoring Program has provided vital insights into South Australia's changing coastline.

By capturing aerial images every 5 to 7 years, the Department for Environment and Water (DEW) helps track the effects of human activities and natural processes on our shores. These images guide decisions on coastal management, ensuring the protection of our coastline for future generations.

A bird’s-eye view of coastal management

Aerial surveys conducted over the Easter long weekend and April school holidays, saw DEW’s Coast Unit soar across the state’s coastline, covering areas from the Victorian border to Port Augusta and even out to the WA border.

The team captured incredible images with a handheld DSLR camera from a Cessna 210 aircraft. These images provide valuable insights into how our coast is being used, especially during peak periods like holidays.

Why this matters

The photos highlight key management issues along the coast—think motorbike and four-wheel-drive access, camping, fishing, and even unauthorised development. The images also reveal natural challenges like coastal erosion, sand dune movement, and the effects of shoreline retreat.

By comparing the latest shots with historical photos dating back to the 70s and 80s, we can see how much our coastline has changed over time, and it helps local councils, government agencies, and community groups make informed decisions about coastal management.

These aerial photos also complement other long-term monitoring programs carried out by the DEW’s Coast Unit, such as beach and saltmarsh profile monitoring. Together, these programs provide a comprehensive view of the coastline and enhance our ability to protect it for the future.

The oblique aerial photos, with their unique bird’s-eye view, work alongside vertical imagery resources to give us a deeper understanding of South Australia’s ever-changing coastline.

So next time you're at the beach, just remember - there’s a lot happening behind the scenes to keep our coastline thriving. With the help of advanced technology and years of expertise, we're ensuring these beautiful shores stay protected for future generations to enjoy!
