The government has an interesting Food Environment Atlas that lets you map things by county.
One neat layer is pounds of fruits/veggies eaten at home per capita. They also have grocery store access, food prices, and a lot more!
The NY Times has come up with a new map using Census data on income, race, housing, same sex partners, and education. Nifty interface!
The data is from 2005-2009, the American Community Survey, which is happens in-between the major decennial census.
They display the data at the census tract level if you zoom in. I cannot tell if they are trying to show block level data - as they have dots representing data on blocs, however I don't think the American Community Survey does blocks.
Income, race, education, health, political participation and more -- all presented in a user friendly format.
The only downside is that their smallest area is a Congressional District. They should have done zip codes! More work, but so much more logical.
I've got heat maps working for operating coal, nuclear, gas, biomass, hydro, and municipal solid waste incinerators.
I broke the lower 48 states in the US into around 700,000 grid squares. Roughly 3 x 3 mile.
You can see the heat map with the markers that link to more detailed facility information, or without them.
There are three different levels of color saturation which let you decide whether to show a map saturated with facilities, or a "points of light" view.
This is my first take on mapping income near the Detroit Incinerator.
They are going to have a big protest of the facility during the US Social Forum.
1999. I copied and pasted FactFinder images together for the 482xx
series of zip codes. You can see that the incinerator (marked as black
I am working on displaying zip codes in Google Maps for the Energy Justice Network power plants map. I'm using ZCTA (zip code) shape files that come from the Census Bureau. You can convert them from shapefile to kml using Geocommons. Unfortunately I need to do this for all 50 states - so it will take a while.
Now the really CRAZY part was that I was unable to get my KML files to show up in Google Maps. They showed up fine in Google Earth.
I recently got the landfills layer of data working on the Energy Justice Network Map. It features 2000 landfills from the EPA's Landfill Methane Outreach Program data set.
Go to the National Map - and turn on the layer (using the radio buttons) to see the landfills!
Walmart Watch just came out with a
map of Walmarts.
You can find new stores or old stores. You can find stores near you. You can find stores that have been stopped. Users can update information about the store.
I like it because it's very similar to what the Energy Justice Network is going to be doing with our power plants map site. You can find power plants (instead of stores), update their information, find groups or start your own group to oppose them, and share resources (files).
A book that I recently noticed. Looks interesting. Unfortunately it looks a little on the theoretical/academic side, which has its place, but I'd really love to see more popular education oriented mapping projects.
The GovTrack site has a map of congressional districts and you can even add the layer to your existing Google Maps mashup.
