Mapping wetland vegetation from Sentinel-2 satellite imagery

Mapping wetland vegetation from Sentinel-2 satellite imagery

Sentinel-2 satellite imagery was used to map freshwater wetland vegetation and saltmarsh across the Gippsland Lakes Ramsar Site in Victoria, Australia.

Supervised maximum likelihood classification models were trained in ArcGIS to identify different land cover types in the imagery.

The mapping was an efficient and cost-effective way to quantify the extent of aquatic habitats that have been identified as critical to the ecological character of the Gippsland Lakes Ramsar site. We were then able to evaluate the current status of ecological character by comparing the mapped extent to the extents defined in the Limits of Acceptable Change (LAC) for the Ramsar Site.

Fun fact:  we call Macleod Morass (pictured) "the Sea Horse" 😀

Riparian LiDAR change assessment and river mapping

Riparian LiDAR change assessment and river mapping

This project is mapping river banks, the channel and riparian vegetation in GIS from aerial LiDAR data collected by Victoria's Department of Land, Water and Planning (DELWP).

LiDAR stands for Light Detection and Ranging. An aircraft mounted laser scans the landscape measuring the distance to the ground. Vegetation cover and structure is captured in the laser reflections that are above the ground.
