Lake Macquarie City Council Asset and Sustainability Monitoring

The Challenge

The Lake Macquarie City Council were looking to obtain accurate data utilising remote sensing for the Lake Macquarie Local Government area.

This data was to be used for Council Asset Management, Environmental Sustainability Tracking and Vegetation Canopy Cover Analysis.

For this they required the following products:

• City-Wide digital elevation model (0.5m)
• City-Wide drainage lines locations and overland flow path
• City-wide tree canopy height model
• City-wide individual tree heights and canopy perimeters
• City-wide drainage pit, bridge and culvert locations
• Retaining Walls on Council owned and controlled lands
• Carbon Sequestration for Rehabilitation Projects

The Solution

Anditi provides a complete solution for Councils that wish to engage the services of a remote sensing specialist. We have expertise in aerial and remote data collection, analysis and interpretation. From LiDAR and aerial Imagery data we are able to extract useful information and generate the custom products.

Using Anditi’s proprietary analytics Engine to run our specialised classification algorithms, we generated a high quality Ground Elevation Model for the entirety of the Lake Macquarie LGA. Through further analysis of the Digital Elevation Model we were able to generate overland flow paths and identify the locations of drainage lines, drainage pits, bridges and culverts.

The Anditi vegetation classification algorithms allowed us to identify all vegetation above 3m to create a canopy tree height and stratification model which defined individual tree canopies, grouped tree canopies and subsequently individual tree heights as well as canopy perimeters.

The Outcome

With the products generated by Anditi from LiDAR and imagery, Lake Macquarie council was able to:

• Assess flood risk and pooling by using the overland flow path data.
• Review performance against their Sustainability Strategy to ensure compliance with Council Sustainability Targets and State Environment Planning Policies.
• Create a baseline inventory of their assets to help with ongoing tracking and maintenance.
