Area of science

Agricultural And Veterinary Sciences, Marine, Remote Sensing and Spatial Analysis

Systems used

Data Stores

Applications used

Time series analysis, fire mapping, vegetation monitoring, mangrove identification; habitat identification and monitoring; seagrass monitoring
Partner Institution: CSIRO| Project Code: GS-11459

The Challenge

Enable time series analysis of satellite data to improve government decision making. Across State government agencies are downloading satellite imagery and not applying consistent corrections for time series analysis. Duplication and inconsistent image processes are being applied. Data storage is an issue for agencies to build adequate image stacks for time series analysis.

The Solution

Central provision of satellite imagery, processed to a recognised standard to enable users to download and conduct time series analysis and other remote sensing analyses

The Outcome

Pawsey’s data centre provides a secure environment to share processed satellite imagery across State government

Core area estimations and habitat use by GPS-collared tammar wallabies translocated to Kalbarri National Park. Graphs display % canopy in vegetation classes over time for each vegetation group. Note graphs: x-axis=time (years): y-axis = canopy cover (%).
Seagrass extent change within Shark Bay's Marin Park before (2002) and after (2004) the marine heatwave in 2010/2011. Black dense (<40%) seagrass cover; red, seagrass loss; dark blue, seagrass gain; light grey, sand; white, not data; gold, Marin Park boundary.
