Incredible Interactive Map of Affordable Housing Statistics in NYC

"Envisioning Development: What is Affordable Housing?" is an interactive Flash-based map of housing and income statistics on a neighborhood-by-neighborhood basis throughout the New York City area.  Although I've seen similar statistical/analytical interactive maps with similar data plenty of times, the aesthetic design and information visualization "impact" of this map is almost breathtaking.  This map is part of an online resource toolkit for urban planning and land use education based around NYC, offered by the Center for Urban Pedagogy.

One feature I thought was interesting, in addition to the elegant interactive map, was the sortable data table view of the underlying dataset.  Even cooler, if you don't feel like using the sortable dataset, the designers of the infographic have helpfully provided a link to download the raw underlying data itself in CSV format, so that you can analyze it yourself in Calc or Microsoft Excel!  Three cheers for open journalism.

National Cancer Institute's Cancer Mortality Map Generator

This is a very useful interface allowing visitors to visualize all U.S. records of cancer deaths over a 50-year period.  Epidemiologists and others can drill down to the county level, selecting from dozens of different types of cancer.  Data can be output in a variety of formats, including static image for copying and interactive Flash maps.

Map Kibera Project: Community-Generated Map of Nairobi's Largest Slum

Maps Show Low-Income Neighborhoods Especially Vulnerable to Heat Waves

When people refer to "heat maps," they can be referring to spectrum-colored maps of values (e.g., maps that show red, yellow, green, etc., based on a range of values), or actual maps of the weather (such as on the back page of USA Today :).  In this post, we'll be examining both: heat maps of heat, so to speak.
