Northey Island 070815 3D Model
Topographic salt marsh survey. MOLA’s SUA was used to survey an area of salt marsh, to assess its morphology and quantify its size. In particular we needed to quantify the proportion of the marsh which had been colonized by plant species.
Approximately 90% of the marsh was inaccessible by foot. Heavily dissected by creeks and drainage ditches, the site could not easily or quickly be recorded using land survey techniques. Owing to the tides, the survey had to be conducted rapidly, so the SUA was the ideal solution.
