Two prominent uses of maps as visual aids in news stories late this week - first up, the Washington Post's state-by-state map of "unauthorized immigrants as a percentage of state population." Based on 2008 data, the map also includes a chart showing the estimated increase of this percentage in Arizona over the past 20 years.
The Global Action Atlas, a new online portal from National Geographic, allows visitors to explore environmental, humanitarian, and cultural projects around the world with an interactive map interface. The site integrates social networking and provides a pathway for recruiting advocates, donors, and volunteers. Well beyond sticking pushpins on a map, this portal aims to "connect people and planet."
The World Bank offers a large data repository of economic indicators, statistics, and other useful tools for mapmakers working in international development. Users can search for data by country or by topic (Aid Effectiveness, Health, Poverty, etc.). In addition to viewing or downloading data, the site presents a nifty visualization tool displaying data on a world map.
The Africa Map project, currently in beta, is an online map and data viewer created by Harvard University. The map combines data sets of numerous categories from a wide variety of sources, allowing thematic maps to be viewed and explored. The purposes of the project, according to the project web site:
Interact with the best available public data for Africa
See the whole of Africa yet also zoom in to particular places
Accumulate both contemporary and historical data supplied by researchers and make it permanently accessible online
Work collaboratively across disciplines and organizations with spatial information about Africa in an online environment
Last week, we added a new example to our resource library: the Environmental Defense Fund's interactive mapping application of "dirty" heating oil in New York City on a building-by-building level. Because this is a great example of a nonprofit mapping application, I asked the EDF's Kira Marchenese to tell us a little bit more about the data sources, mapping tools, and processes that took place to create this project.
