Go Philly! GIS helps improve access to healthy food in the city

Yesterday’s NY Times had an opinion piece praising Philadelphia’s efforts in recent years to improve access to healthy food for its most disadvantaged neighborhoods and citizens.  In ‘Go Philly!’, Mark Bittman describes the collaborative efforts of Philadelphia municipal government, the Commonwealth of PA and a whole host of local non-profits (including my former employer, the newly renamed  Greater Philadelphia Urban Affairs Coalition) in developing programs to bring supermarkets and healthy food options to under-served neighborhoods.

What he doesn’t describe is the critical role that GIS has played in bringing these programs to life.  See below for some background information and resources related to using GIS for improving access to healthy food.

1. Watch this short video (Ch. 3 of Episode 2 from Penn State’s Geospatial Revolution video series) to learn more about the role of GIS in Philadelphia’s ‘healthy food’ success story.

2. Read reports from the Food Trust and The Reinvestment Fund (TRF) describing their work in Philadelphia and other communities. Both organizations are Philadelphia-based non-profits that have been at the center of Philadelphia’s efforts to improve access to healthy food.

3. Watch a video created by TRF in collaboration with the Brookings Foundation to describe their use of GIS and findings in their  “Getting to Market” report on healthy foods initiatives across the U.S.

More about scale: the true size of Africa

Here’s another in a series (see here and here) of interesting maps that address scale. Created by Kai Krause, the map aims to show the true size of Africa by visualizing all of the countries and regions that could fit inside the continent – including the U.S., China, India, Japan and all of Europe.  Krause calls the map “a small contribution in the fight against rampant immapancy” – or insufficient geographical knowledge.

Bucknell student uses ArcGIS in research on sleeping sickness

Below is an interview with Daniel Dougherty ’12, a History and Geography major, discussing his use of GIS for an analysis of the impact of climate change on sleeping sickness.  The research project was conducted as part of Prof. Duane Griffin’s Geography 204 course Applied GIS. In the interview, Dougherty describes the data and methodology he used for the project and talks about some of the conclusions he drew from his analysis.

The images below show some of the maps Dougherty was able to produce using ArcGIS, MaxEnt and data from WorldClim.

How big is it really?

Back in December I posted about an NPR story about map scale.  I got so excited about the baseball on the moon map that I neglected to point out the other really interesting link from the story – to the BBC Dimensions website.  Dimensions (or, ‘howbigisitreally’) has a tool that lets you plug in any zip code or location and then choose from a list of events, places or things that you want to superimpose onto your area. See below for a map showing the area that the Guantanamo Bay Naval base would occupy if it was located in Lewisburg. I’ve also included maps showing what the ancient walls of Athens and the Gulf oil spill would look like if superimposed over the Lewisburg area. The Dimensions website has numerous places, events and things to choose from in making your map, including: the war on terror, ancient worlds, the industrial age, space, environmental disasters, depths, cities in history and more.

Mapping America block by block

The front page of yesterday’s New York Times featured maps and stories based on recently-released data from the U.S. Census Bureau’s American Community Survey. As described by the team at Social Explorer, “the latest [American Community Survey] figures are the single largest data release in the Census Bureau’s history, providing a look for the first time since 2000 at a variety of characteristics, including income, race, immigration and commuting habits for people in areas as small as just a few square blocks.”

A number of searchable, interactive maps – developed jointly by the New York Times and Social Explorer – accompany the articles. Click here to explore the maps. Click below to read the articles.
