Topic: Two species interactive mapping
When two species are mapped on the interactive map one over-writes the other.
The result is meaningless, any square may be showing both, or only one, species. How can one guess which species is overwriting the other or what is behind?
What is needed is the ability to plot two species on one map, but to have squares where both occur in an intermediate colour or the solution may be as simple as a square dissected with a diagonal line (bottom left to top right) with one colour on each side of the line. Clear simple and oh so much more useful!
