Kakadu LIDAR Project 2011 Modelkeypoints
Model key points are statistically thinned data points that represent the main changes in a sampled surface. The Key Points are classified with code 8 in the LiDAR point classification scheme. Advantages in their use are significant reductions in data volume and reductions in data noise. There are disadvantages in using this data as has been a los... mores small features which may be potentially significant for certain applications. eg hydrology less

Climate and Weather: Ecology
Fugro Spatial Solutions (FSS) were awarded a contract by Geoscience Australia to carry out an Aerial LiDAR Survey over the Kakadu National Park. The data will be used to examine the potential impacts of climate change and sea level rise on the West Alligator, South Alligator, East Alligator River systems and other minor areas.
The project area was flight planned using parameters as specified. A FSS aircraft and aircrew were mobilised to site and the project area was captured using a Leica ALS60 system positioned using a DGPS base-station at Darwin airport. The Darwin base-station was positioned by DGPS observations from local control stations. A ground control survey was carried out by FSS surveyors to determine ground positions and heights for control and check points throughout the area. All data was returned to FSS office in Perth and processed. The deliverable datasets were generated and supplied to Geoscience Australia with this metadata information.

1177.2 Northern NERP - Remote Sensing
There is limited biological data from across the remote and inaccessible northern Australian coastline that can be used to inform bioregional planning processes, development approvals and, ultimately, biodiversity conservation.
Habitat availability and biophysical factors such as water depth, light availability and turbidity are important determina... morents of coastal and marine biodiversity.
Managing the natural resources of the Alligator Rivers Region in Kakadu National Park relies on long-term monitoring of key biophysical parameters in the wetlands and adjacent seas where little is known about biodiversity and ecosystem processes. Remote sensing provides a cost-effective monitoring and assessment tool in this data-sparse region, allowing the detection of changes across habitats, and trends in coastal water quality. less
