Other types of habitat map


There are many other types of habitat- related geographic data that can be plotted on a map, but these are not pursued in detail in this MESH Guide.
  • Sample data - Biological samples (e.g. from video or grabs) can be plotted on a map as point data. Once assigned to habitat types, they are integral to habitat mapping as the ground-truth data, but the plots themselves can also be considered as simple habitat maps.

  • Acoustic data - A plot of acoustic features (e.g. side-scan images) may be directly interpreted as habitats but need adequate ground-truthing to confirm any interpretation of habitat features.

  • Interpolated maps - Some point data can be interpolated to create a continuous coverage. For example, point habitat class data can be interpolated using nearest neighbour or other interpolation procedures. However, if the interpolation is not augmented by remotely-sensed data then these maps are not habitat maps in the sense used in this Guide.
  • Density plots - Point data can be summarised in density plots or presence/absence in a predefined recording grid, such as ICES rectangles. These plots are summaries of observations where no modelling involving remotely-sensed data has been used to predict distributions.
