Purpose

Facilitates historic hindcasting of marine habitat distribution and extent across Victoria's nearshore waters 

Supplemental Information

Related Documents: None Marine habitat mapping attributes derived from this imagery, and associated marine ground truthing surveys, have been integrated with various additional data to create the Statewide Marine Habitat Map 2021 (see below URL for full description). For Port Phillip Bay, a raster habitat distribution model has been created using machine learning tool to integrate ground truth data and environmental predictors (https://uat-metashare.maps.vic.gov.au/geonetwork/srv/eng/catalog.search;jsessionid=625C05947EC8E50011BF1BD70F511FC3#/metadata/df94da5d-ae99-535e-9f12-8be535c0e293)

Comments

Dataset is able to reveal habitat features of the intertidal and shallow subtidal environment to a depth dependent on the prevailing atmospheric and water quality conditions at the time the image was captured.
