Marine and Coastal GIS Mapping

A new and important area of Aquenal’s work is GIS mapping of the foreshore environment and coastal values. Environmental indices relating to foreshore values, pressures and condition have been developed and mapped using innovative approaches that have potential application to coastal management systems Australia-wide and in other parts of the world. This work complements our expertise in underwater and intertidal habitat mapping, which forms an integral component of most projects Aquenal has performed. We have conducted habitat surveys and constructed habitat maps for hundreds of survey reports, including those produced for marine farm environmental surveys, threatened species surveys, environmental impact assessments, monitoring programs and underwater inspections. …Further information

Mapping of coastal environmental indicators

As part of Tasmania’s Regional Natural Resource Management Framework, we have been conducting two projects which will cumulatively map coastal environmental indicators for the entire Tasmanian coastline:

  • Assessment and mapping of foreshore values, condition and pressures for the Southern Natural Resource Management Region, Tasmania
  • Assessment and mapping of foreshore values, condition and pressures: a coastal management tool (North and Cradle Coast Natural Resource Management Regions) - ongoing

In the Southern NRM Region project we characterised coastal management issues by compiling mapping layers for the following four main indices and 13 associated and more detailed sub-indices. Information for these indices was based on compilation of approximately 60 relevant datasets identified through literature and database reviews, web searches and field studies:

  • Natural values
  • Human use values
  • Pressures
  • Condition

The project for the Southern NRM Region has been completed and the final mapping layers are available under the Natural Environment (Coastal Values) category on the Land Information System Tasmania (LIST) website. These data bridge a gap between existing mapping of coastal and marine habitats, form a basis for strategic management of foreshores in the region, and establish benchmarks and reference sites for assessing future change. This approach is now being developed for the North and Cradle Coast NRM Regions of Tasmania using a similar technique supplemented by new compatible mapping technologies.

Underwater and intertidal habitat mapping

Habitat maps produced and associated data sources used in our environmental projects are summarised below:

  • Regional and local habitat maps created using digitised aerial photographs and other images
  • Bathymetry maps
  • Habitat maps based on bottom hardness sensing echo soundings and filming/sampling ground truth surveys, including characterisation and mapping of a range of hard and soft sediment substrata categories
  • Maps of biological communities, such as mangroves, seagrass and algal beds, rocky reef communities and wading bird sites
  • Mapping of species distributions and population characteristics
  • Tidal mapping using a pressure logger to investigate exposure times for intertidal habitats

Habitat maps have been generated using the software packages ®Mapinfo Professional and ®Manifold System.
