Landgate now has a complete, current, and seamless DEM covering the South West region of Western Australia. Improved technologies and processing techniques have resulted in significant differences when compared to the previous DEM produced over the area, including:

• 4x more data at 5m grid intervals
• greatly improved accuracy with 97 percent of points falling within ± 1m
• seamless data between capture projects; and
• continual updates through the Capture WA program .
