Using data collect but not mapped

Habitat maps show the habitat classes as defined by their common characteristics. However, it is likely that your point sample data will contain much more information than can be used to create a habitat map, such as details of substratum cover and species abundances.
Information is not lost just because it cannot be displayed as part of the base layer habitat map. There are many ways of using and displaying information. The strength of the habitat map is that it gives spatial context for all the other information.
The flow diagram below summarises the process of utilising and displaying sample information with regards to habitat mapping based on remotely-sensed data. The sample points will need to be tagged with habitat class information and each class being sampled a few times before the samples can be used to interpret the remote data in terms of habitat classes. Other sample information can be displayed as an overlay of point data.

Lastly, the detailed information can be used to draw up a detailed description of a habitat class, giving information on likely diversity, species composition and variability that might be encountered. However, this information is not part of the map as such but should be made available to the end user to help their understanding of the habitat classes present on the map. Such information is often presented in structured format supported by photographs or video clips of the seabed (see following figure for an example).
