There is no standard way of mapping model results; however more-and-more models output data that is GIS (Geographic Information System) compatible. Once the data is in a GIS the user is able to overlay it onto many different layers of information including layers showing the environmental predictors (such as soil types or rainfall areas) and administrative information (such as roads or country boundaries).
An important part of mapping model results is how they are symbolized and represented on the map.
Colour associations: it is important to choose the colours carefully when symbolizing model results since certain colours have certain inherent meanings, such as red might symbolize danger, where blue typically symbolizes water.
Shades: also limit the number of shades of the same colour, the human eye can only differentiate between approximately 20 different shades of a single colour.
Symbol complexity: avoid complex point symbols that are difficult to distinguish when the map is printed. Furthermore avoid complex hatching symbols which the human eye struggles to focus on, i.e. thin stripes.
Cluttering: avoid cluttering the map with too much information, such as all roads, instead of major roads only.
Background information: the addition of a satellite image or aerial photo can make a substantial improvement to how easily users are able to locate predicted locations on a map. Take care that the landmarks are clearly visible on the image.
Welcome to Biodiversity Advisor 2.0!
Biodiversity Advisor, developed by the South African National Biodiversity Institute (SANBI) and its Data Partners, is a system that will provide integrated biodiversity information to a wide range of users who will have access to geospatial data, plant and animal species distribution data, ecosystem-level data, literature, images and metadata.
The integrated information comes from our much-loved Botanical Database of Southern Africa (BODATSA) also known as Plants of Southern Africa (POSA), Zoological Database of Southern Africa (ZODATSA), Biodiversity Geographic Information System (BGIS), SANBI's institutional repository (Opus) and others.
The system is still under development, so you may find a few bugs/issues. If you do, please report it via the error reporting button available in various sections of the website or provide us with any useful feedback you may have via the ‘Give us feedback’ option available in the sidebar menu. You can create a free account for yourself by clicking on the user profile icon which will take you through to the login page. Here you can choose the ‘Create an account’ option or simply fill in your details if you have an account already. Having an account on Biodiversity Advisor will provide users with free access to biodiversity resources.
In future, Team SANBI will be able to log in using their day-to-day login details, BGIS users will be able to use their existing accounts and details, and general users will be able to log in using their LinkedIn profile, but for now you will need to create an account.
