In BirdVis we propose Tag Cloud Lenses as a way to assess the
relative ``importance'' of set of variables defined on a domain
(e.g. US map). In the screenshots below, these variables
represent habitat preferences for a bird species in the region
covered by the lens in a certain time window.
We allow the use of multiple lenses to uncover regional
differences on habitat preferences and also allow lenses to be
coordinated in multiple views to reveal changes in habitat
preference in time.
The same idea of coordinated views can be used to investigate
In BirdVis as well as occurrence maps (top row) we also feature
occurrence variation maps (bottom row) with independent
colormap controller. Note how the occurrence variation sign and
intensity is not so clear on the top row.
Here is an example of playing with the colormap controller to
hightlight two ranges of occurrence probability.
