The previous post showed a simple cartogram of the US using the eBird species counts by state in order reshape the map. The relative sizes of the states in the cartogram are proportional to the species diversity. A more detailed version can be obtained by using the species counts at the county level. Data as… Continue reading eBird Cartograms for US Counties

eBird Species Cartogram for the United States
The previous post presented a cartogram for global eBird data by county. Here, we do the same for the States (and Washington D.C.). It is worth noting what the starting conditions are; that is, what base map will be used to generate the cartogram. I am using the WGS84 geographic coordinate system/projection, shown here without any morphing: A… Continue reading eBird Species Cartogram for the United States
Reshaping the World with eBird Data
Cartograms provide a pleasing way to present geographical data. The idea is to redraw a map so that the relative sizes of its units (e.g. countries, states, counties, etc.) correspond to some measured quantity. A common example is a cartogram of population by country, in which the relative sizes of China and India become exaggerated, while… Continue reading Reshaping the World with eBird Data
Thirty Years of eBird “Top 100” Data
The eBird site administered by the Cornell Lab of Ornithology was launched in 2002 and has arguably advanced birding more than any technology since binoculars. Beyond acting as a repository for one’s records, it affords many tools to explore the data submitted by tens of thousands of birders, while giving ornithologists an ever-growing data set… Continue reading Thirty Years of eBird “Top 100” Data
A Global Big Working Year for Charity
The idea of a Global Big Working Year is to see as many species as possible between Jan 1 and Dec 31 without geographical constraint, but rather with a more pedestrian limitation: you have to work normal hours at your full-time day job, just like during any other year. (And no, if your full-time day… Continue reading A Global Big Working Year for Charity
