Sea floor and bathymetry mapping: Rottnest Island, Western Australia, AU

Inventory, assessment and monitoring of Mediterranean Wetlands: Mapping wetlands using Earth Observation techniques, 130 - 133
Rottnest Island is a marine reserve lying 20 km offshore from Perth, Western Australia. It has a subtropical climate and, due to the south flowing, warm Leeuwin Current, many tropical as well as temperate marine species are found here. Many marine organisms are considered as isolated, at their southernmost extent. The marine reserve is mostly in shallow (less than 20 m depth) water and is made up of the following main habitat categories: sand, seagrass, mixed seagrass and reef, reef, intertidal platform and reef wash. The reef habitat (~ 45%) occupies the largest area, followed by seagrass (21%) and sand (20%) (Rottnest Island Management Plan 2003-2008). The island also has important coral communities, though not extensive in cover. Bathymetry of the waters surrounding Rottnest Island is quite varied, owing to the presence of many submerged limestone formations, favourite spots for divers and snorkellers.

How can I map littoral sea bottom properties and bathymetry?
Published 2008

Littoral sea bottom properties can be mapped from Earth observation sensors if the reflection of the sea bottom contributes a detectable part to the signal measured by the sensor. This sea bottom reflection must be separated from all other simultaneously measured portions of light for further mapping and classification procedures. Other contributors of light scattered to the sensor are atmospheric molecules and aerosols, the water surface reflection, and light scattered and absorbed due to particular properties of water constituents and the pure water itself.

Land use and land cover mapping for catchment monitoring and management with remote sensing methods

Remote sensing techniques are evaluated for their use in land cover and land use mapping. Catchment monitoring and management requires detailed and up to date information about the surface runoff, cover and use. Remote sensing as a data gathering technique can rapidly deliver very detailed studies of the ground surface. Choice of the instrument, platform and analysis technique varies however depending on the size of the catchment, number and complexity of parameters required, budget and availability of the trained staff to undertake data analysis.
