The frequency of airline flights may thus be a better predictor of non-local ties than physical proximity

Weave (BETA 1.0) is a new web-based visualization platform designed to enable visualization of any available data by anyone for any purpose. Weave is an application development platform supporting multiple levels of user proficiency – novice to advanced – as well as the ability to integrate, disseminate and visualize data at “nested” levels of geography.

Vernacular geography is the sense of place that is revealed in ordinary people's language.

An idiosyncratic example of an mapping project being driven by a personal obsession is Michael Cook’s ongoing exploration of the Toronto sewer system. Wearing urban infiltration, geography graduate student and photographer hats, Cook has been researching the underground constructed landscapes of the Greater Toronto Area for the last decade.

OpenTreeMap provides an easy-to-use public inventorying platform that enables individuals, organizations, and governments to collaboratively contribute to an interactive and dynamic map of a community’s tree population.

When the data is the social graph of 500 million people, there are a lot of lenses through which you can view it. One that piqued my curiosity was the locality of friendship. I was interested in seeing how geography and political borders affected where people lived relative to their friends. I wanted a visualization that would show which cities had a lot of friendships between them.

TOO MUCH gathers thoughts about cities, the people who live in them, and the changes affecting our society and our environment. It's a magazine about romantic geography.

I arrived at college in 1984 with my electric typewriter and a bit of BASIC learned in high school. I was a geography major, and learned to make maps in a cartography lab with vellum, ink, light tables, X-acto knives, and rub-on letters.

It consists of the maps of 20-some of the 30-some airports I spent time in over the last 12 months and represents a particular experience of travel that I've had.

The response .. "I was trained in France! What's your experience in geography?" When I replied I was a web developer, they scoffed.

An all-curves map smoothes away the awkward kinks, revealing the underlying structure of the network (below). In usability tests, this version is 30 per cent faster for planning than the official map.

Myriahedral projections are a new class of methods for mapping the earth. The globe is projected on a myriahedron, a polyhedron with a very large number of faces. Next, this polyhedron is cut open and unfolded. The resulting maps have a large number of interrupts, but are (almost) conformal and conserve areas. A general approach is presented to decide where to cut the globe, followed by three different types of solution. These follow from the use of meshes based on the standard graticule, the use of recursively subdivided polyhedra and meshes derived from the geography of the earth. A number of examples are presented, including maps for tutorial purposes, optimal foldouts of Platonic solids, and a map of the coastline of the earth.

The following maps represent the first stage of a project I am embarking on to map out some of the spatial contours of Wikipedia. Data were obtained from the August 2009 Wikipedia geodata dump organised by user Kolossos. The information was then ported over to a GIS. There are almost half a million geotagged Wikipedia articles (i.e. Wikipedia articles about a place or an event that occurred in a distinct place), so the preparation time alone for the files needed to create these maps was almost a week.
