…in ways that maps don’t
Maps are predictable
Navigation is predictable
Every pixel counts
Ground truth
Relative and absolute navigation

Phylogeny has none of this
There are few constraints on how we can draw trees

What would third dimension represent?
@wellcometrust
Pretty, but…
Is 3D useful?

@rob_beiko
GenGIS-style trees on Google Maps

Challenges
• Does 3D have a role beyond being a gimmick?
• Geospatial phylogenies

Challenges
• A visualisation of large trees that is as intuitive and as useful as Google Maps
• A platform, not a picture
Touching the tree
@dr_pi
@kzelnio Think how great of a tool that could be at museumson a large flat screen at 4 year old height.

Challenges
• Intuitive, easy to use touchable trees
• Teaching and research
• Gamefication
Where are the trees?

Why aren’t we archiving these trees?

Challenges
• Interactive trees for publications and databases (eventually database = publication)
• Software to create pretty, machine readable visualisations
