The Changing Shoreline of New York City
Uses historical maps, from the New York Public Library’s collection, to explore how Manhattan has physically grown in size during its brief history. As you scroll through this impressive story map historical maps are used to show how Manhattan's many rivers, creeks, brooks and bays have been managed or even built over. These historical maps are overlaid on top of a modern map of New York. Each has an opacity control that allows you to directly compare the historical with the modern map of the city to illustrate how Manhattan's landscape has changed.

A genetic map of the world – Gene Expression
The above map is from a new preprint on the patterns of genetic variation as a function of geography for humans, Genetic landscapes reveal how human genetic diversity aligns with geography. The authors assemble an incredibly large dataset to generate these figures. The orange zones are “troughs” of gene flow. Basically barriers to gene flow.  It is no great surprise that so many of the barriers correlate with rivers, mountains, and deserts. But the aim of this sort of work seems to be to make precise and quantitative intuitions which are normally expressed verbally.
