I’ve been experimenting with drawing “geophylogenies” on web maps and have created a live demo at GeoJSON phylogeny demo All a bit crude, but the idea is to take either a NEXUS tree file with added geographical coordinates, or query the BOLD database of DNA barcodes (most of which are geotagged) and create an interactive phylogeny on a map. The demo uses OpenStreeMap, I’ve code for Google Maps as well (hope to add this to the demo shortly). The layout borrows from GenGIS (see GenGIS: A geospatial information system for genomic data and The GenGIS wiki ) but doesn’t need a standalone program. There are some other advantages to using GeoJSON, such as storage in document databases like CouchDB, but I’ll blog about these.
To give you a sense of the visualisation, below is the classic Banza example that I used in 2007 when I started playing with trees on Google Earth iPhylo: Google Earth phylogenies, inspired by Bill Piel’s pioneering experiments.
