Geographic Information Systems (GIS)

Below is an example of the data that can be gained from a single survey shown over a base map. Here the bathymetry (depth), numbers of fish per hectare and the location of seagrass are given.
Geographic Information Systems (GIS) are a way of displaying and analysing spatial data. In our work these data commonly relate to the distribution of fish (in terms of numbers of individuals, biomass and/or mean sizes), seagrass beds and bathymetry (depth). The data can therefore be plotted upon a base map and this can reveal important relationships. The visualisation of the data in this way helps to inform planners, developers and environmental managers upon the nature of the environment so that any potential impacts can be minimsed.
