Azavea Supports Public Redistricting Competition in Philadelphia

I’m excited to announce that this week we rolled out a new implementation of the DistrictBuilder software for our home town, Philadelphia.  The new web site, FixPhillyDistricts.com, is the result of a collaborative effort between several local organizations:  WHYY NewsWorks, the Philadelphia Daily NewsPhilly.com , Penn Project for Civic Engagement, and Azavea.  While the DistrictBuilder software has been used to support competitions in Virginia and Arizona, Fix Philly Districts will be the first time it’s being used for a municipal public redistricting competition.

This isn’t a typical Azavea project: there is no funding to support it – all of the partners are doing the work pro bono; and while our Cicero API and the work we’ve done on DistrictBuilder is clearly engaged with the geographic elements of the democratic process, Azavea does not usually wade into the actual scrum of politics.

So, why get involved?  In 2006, using our Cicero database of global legislative districts, Azavea released the results of an internal research project on legislative district compactness in the form of a Gerrymandering White Paper.  In 2010 we released a revised version of the research, this time in the context of the 2010 Census and the 2011 redistricting process.  Both studies revealed that Azavea’s home town, Philadelphia, has some of the most contorted local council districts in the United States.  We want to leverage the DistrictBuilder software we’ve been creating over the past year (in collaboration with leading redistricting experts at the Public Mapping Project) to make a contribution toward changing this poor showing.

In Philadelphia, the redistricting process is controlled by City Council.  We believe that the best government is one in which citizens are engaged in the democratic process, and drawing the lines that determine how our representatives will be elected is a critical part of this process.  We have created FixPhillyDistricts.com to both enable the public to learn about redistricting and to encourage public engagement in the process.  The effort is also meant to demonstrate that an open, public process based upon objective criteria can produce fair, legal council districts in Philadelphia.

How can you help?  Take a few minutes to visit FixPhillyDistricts.com.  From there you can do two things: 1) you can create an account and draw a Philadelphia City Council district plan (even if you don’t live in Philadelphia); and  2) using the social media buttons available on the site, help the Fix Philly Districts partners tell other civic-minded organizations, researchers, and members of the public that web-based, collaborative and public redistricting is a reality that can be implemented in other cities, counties, and states.  Together, we can redraw the map on redistricting.

More about Fix Philly Districts
We are really encouraged by the amount of press coverage the project has already received. You can see a roundup of local coverage in the Azavea News Room.

More about DistrictBuilder
DistrictBuilder – the software that powers the Fix Philly Districts site — was developed in collaboration with leading redistricting experts at the Public Mapping Project.  It is open source, which means that the software is transparent and available to anyone to build their own redistricting web site.  Azavea folks are also available should you be interested in an online redistricting project in your area.  In collaboration with the Public Mapping Project, we will be continuing to add new features and capabilities over the next several months.

OpenDataPhilly.org to Launch on April 25

Open Data Philly Home

I’m excited to announce that we will be rolling out a new open data portal for the Philadelphia region, OpenDataPhilly.org on April 25.  Open data and government transparency have been increasingly visible concerns over the past few years.  Almost 10 years ago, the City of Philadelphia made its GIS data available to the public at no charge, and, at the time, was one of the first and largest municipalities in the world to do so.  That data has been available on PASDA, the spatial data clearinghouse for Pennsylvania, ever since.

In the past few years, many municipal governments have been making a public and concerted effort to improve the transparency of their government operations by releasing significant and useful data sets.  Washington DC deserves credit for playing a leadership role in this respect.  DC was arguably the first major city to not only release downloadable data sets but create real-time streams of data from operational databases.  Today the District provides access to 475 datasets from multiple agencies and in a variety of formats, CSV, RSS, KML, XML and shapefiles.  In May 2009, the federal government launched Data.gov with just 47 data sets.  Today there are 380,000 data sets (of which more than 376,000 are geospatial). Many other cities have followed suit. A few of them include:

But Philadelphia isn’t in that list.  While the City was an early and unsung leader 10 years ago, these recent efforts by other governments have left it behind.  There is no Philadelphia Open Data web site.  So why is Azavea building one? Well, we really have Roz Duffy to thank.  She encouraged me to get involved with the Open Access Philly task force, a group sponsored by the City.  I attended my first meeting in January and was impressed by the range and diversity of the people who have been attending these meetings over the past year.  After the first meeting, I felt like Azavea was actually in a good position to create something that would both serve to bring the various City data sets together in a single catalog as well as extend the catalog to other resources.

So while the Open Access Philly task force is supporting this new catalog, OpenDataPhilly.org is not a City project.  The City government doesn’t have the resources to build something right now.  But I’m proud that Azavea is building it.   That said, this is not a typical project for us.  We don’t build open data portals – we build spatial data analysis and visualization tools.  But I felt this was important for a number of reasons.  First, I kept hearing other technology people in the region lamenting how Philadelphia was being left in the dust by other cities.  That’s sad because there’s actually far more data available than most people realize, but that was certainly a common perception.  Second, much of Azavea’s work depends on open standards and the broad availability of useful data sets.  By making it easier to find data, we are supporting the ecosystem that supports our business.  Third, I buy into the idea that open government can encourage both better government and a more engaged citizenry.

Because Azavea is not the City, OpenDataPhilly.org is different from most other open government data portals.  We have taken a look at a lot of them and we’ve done our best to incorporate what we thought were the best parts.  But we’ve decided to try some different ideas that we hope will make the catalog more useful.  First, the catalog is not limited to data from the municipal government – we have also incorporated data from non-profits, universities and commercial organizations.   Second, this catalog is not just about data; we’ve also included data-centric web and mobile applications as well as developer-oriented APIs and other structured data feeds.  Third, we realize that data for its own sake is not really all that helpful.  To be useful, the data needs to actually be put to use in new applications, visualizations and stories.  So the OpenDataPhilly.org site includes an Idea Gallery, a feature similar to London’s Inspirational Uses page.

Open Data PhillyWhen the site rolls out on Monday, it will not only be a catalog of existing data sets, applications and APIs, it will also include a series of new geodata APIs that the City has implemented over the last few weeks.  So the act of constructing the catalog has inspired the City to release some data sets in a new and useful way.  That’s pretty exciting.  From our perspective, that means the effort is already a success.  Furthermore, while the City didn’t pay for the development of OpenDataPhilly.org, that doesn’t mean they didn’t help.  Several staff at the City’s Office of Information Technology, including Jeff Friedman, Stuart Alter, Paul Wright, Jim Querry, Brian Ivey, Walter Svekla and others have supported it’s development through both encouragement, suggestions and the hard work required to roll out these new APIs.

The rollout will also coincide with Philly Tech Week, a week-long celebration of technology and innovation in Philadelphia organized by Technically Philly.  Open data serves as bookends for the week.  Azavea will be rolling out OpenDataPhilly.org on Monday at noon at WHYY.  On Saturday as part of the BarCamp NewsInnovation at Temple University, Tropo is organizing an Open Government Hackathon.  The Hackathon will aim to build new applications that use the data listed in the catalog.

Want to get involved? Here are a few ways:

  • Show up on Saturday for the Hackathon and join a team.
  • Got data? We know we probably missed a bunch of useful data sets. There will be a mechanism for organizations to submit information about their data sets for potential inclusion in the catalog.
  • Is a critical data set missing? We’ll have a way for you to ask for it and vote on other people’s requests.
  • Write to your city, state and federal legislators and ask them to support open government data policies. We can help you with that too. Check out Azavea’s Cicero API.
  • If you are a developer, build some apps that use the data. Or, better yet, apply for Code for America, an innovative approach to public service where you can apply your skills to making government work better for everyone.
  • Say something with the data. Download some data and develop a beautiful visualization that tells a story. Then submit it to the Idea Gallery.

Seminar Announcement: An Introduction to Mapping for Nonprofits

Azavea’s Spatial Analysis and Cartography team has worked with nonprofits across many domains to help them use mapping to answer a variety of research questions.

In health and human services, the Utility Emergency Services Fund (UESF) approached us to help them demonstrate to each member of City Council the magnitude of the organization’s work assisting low-income families in their district.  We also worked with the Delaware Valley Association for the Education of Young Children (DVAEYC) to develop maps visualizing the availability of quality childcare relative to need.

To support the economic development efforts of the Pennsylvania Horticultural Society, Azavea conducted an impact assessment using spatial statistical techniques like Geographically Weighted Regression (GWR) to explore the relationship between property values and cleaning and greening efforts on vacant lots.

Arts organizations have also found value in our spatial analysis services to help them communicate more effectively with their supporters.  The Greater Philadelphia Cultural Alliance’s advocacy efforts rely on our Cicero legislative information service, while The Wilma Theater turned to us when they wanted to analyze their patron data to identify promising markets they may have been missing.

At the national scale, we worked with the political transparency organization MAPLight.org to automate the generation of more than 400 maps to visualize the extent contributions to members of the U.S. Congress had originated outside of each legislator’s home district.

While these organizations have recognized the ability of maps to help them achieve their institutional goals, there are many more nonprofit organizations that possess a wealth of spatial data without even realizing it.  Azavea has partnered with NPower Pennsylania to offer a half-day workshop that will get you started thinking spatially and will illustrate how maps can be powerful tools for planning programs, demonstrating outcomes, and communicating strategically.

Covered topics include:

  • Best practices for collecting, managing and sharing geodata
  • An introduction to geocoding
  • An overview of key map types
  • Pointers to free and low-cost resources to get you started with mapping and GIS

This is more a conceptual than a technical workshop so no experience with mapping is necessary, but the content will best suited to people familiar with their organization’s data.

“Putting Maps to Work: Using your data for planning, reporting and advocacy” will take place on March 14th and March 17th from 9am to 1pm at NPower PA’s Center City location and will cost is $20 (includes a boxed lunch).  WARNING: Both dates are now sold out.  Interested in another mapping for nonprofits seminar? Let us know!

Mapping Walkability: Finding the Best Places in Philadelphia to be Carfree and Carefree

"'...how can I find a walkable community?' I'm glad you asked...."

It is clear that we Americans face many challenges today. The prospect of global climate change has many of us look for ways to reduce our carbon footprint. Record high energy prices earlier this year have made us all aware of how vulnerable we are to such price spikes. Such challenges are daunting, but many people have turned to an unlikely solution: walkability.

The core principle of walkability is quite simple: give people the option to live their lives without having to get in a car. Less need for a car instantly produces a number of positive individual benefits including 1) paying less for fuel, maintenance, parking, and insurance, 2) less exposure to energy price spikes, 3) reduced greenhouse gas emissions, and 4) a healthier, more active lifestyle. And these benefits become more pronounced if you are able shed a car altogether: no more car payment!

This is all well and good, but how can I find a walkable community? I’m glad you asked.

While living in Seattle, I became intrigued by Alan Durning of the Sightline Institute and his concept of a “walkshed” that scored a location based on the quantity and diversity of amenities within a one-mile radius. A year later, Walk Score, which drew heavily from Durning’s walkshed concept, went live as the first application in the world to map walkability. While Walk Score is a fantastic application with a clever methodology, it has a number of acknowledged limitations. Using Philadelphia as a prototype and as part of Azavea’s 10% research project program, I am currently researching ways to overcome some of these limitations to more accurately calculate and map walkability.

Map

train, subway, or trolley stop.

The first requirement of this new methodology is the ability measure the walkability of a location by determining the actual walking distance to a variety of assets. In many cases, “as-the-crow-flies” distances are accurate enough, but that accuracy can degrade quickly with the presence of barriers (rivers, highways, etc), disjointed street networks, or extreme topography. In other words, I need to be able to programmatically detect the actual walking distance to my favorite restaurant on the other side of the Schuylkill River. It may only be a quarter mile as the crow flies, but being bound to the street grid could significantly increase that distance.

The most time consuming step was the development a friction layer for the entire city. This layer had to accurately represent the “friction” a person would encounter walking around the city. For example, a city street or park would represent low walking friction while navigating across a river or highway would be quite high. By taking streets, trails, parks, rivers, highways, and railroad tracks into account, I was able to calculate the walking friction of every point in Philadelphia. This friction layer now allows me to calculate the walking distance to any defined point in the city. Above, you see a sample screenshot that represents the walking distance from every point in Philadelphia to the closest train, subway, or trolley stop.

I find this research incredibly fascinating, but the best part is that this project is just getting started! I have several new walking distance layers in the queue for amenities like bus stops, car-share locations, parks, grocery stores, farmers markets, cultural venues, and more. After these data sets are complete, I have plans to roll out a publicly available web application built on Azavea’s DecisionTree product. This application will not only mimic most of Walk Score’s functionality, but will allow each user give personalized weights to each walkability indicator.

Mapping Citizens’ Voices

"Turn it around in a little over a week? That was where the fun began."

“Democracy is the worst form of government except for all those others that have been tried.” —Winston Churchill

The Citizen’s Compact with City Hall (http://www.reformballot.org/) is a grassroots democracy action born out of the Reformer’s Roundtable, an organization convened by Philadelphia Forward (http://www.philadelphiaforward.org/). We like what these people are trying to do to improve city government in Philadelphia, so we’re lending a hand.

The idea was to get a quick and intuitive representation for the geographic distribution of individuals who sign the Citizen’s Compact with City Hall. When a visitor signs the compact, their contact information and address are saved. The Reformer’s Roundtable wanted to show a map that changed as more and more citizens volunteered to become involved. Not only that, we wanted to protect each individual’s address using some geographic aggregation. Turn it around in a little over a week? That was where the fun began.

Azavea turned to ESRI’s ArcWeb Services, GoogleMaps and Open Source software to achieve this dynamic, interactive map. The addresses are geocoded with ESRI’s ArcWeb Services (http://www.arcwebservices.com/), processed and stored in a PostGIS database, and rendered in OpenLayers via MapServer using the GoogleMaps basemap. All in all, a tidy package that processes visitor information and dynamically generates a map of aggregated citizen distribution.

This is an exciting project for us – it is a good cause and it involves an intriguing constellation of geographic information technologies. As part of our staff’s research, we have developed a bit of expertise in each of these realms, but hadn’t had the opportunity to bring them all together in one project. We are excited to see it in action, and we hope you take a moment to check it out.

And if you live in Philadelphia, please consider signing the Citizen’s Compact. When you sign the compact, you’ll get access to a wiki where you can contribute your own ideas for political reform in the City. In a couple of weeks, you’ll have a chance to rate those ideas. Then, the top-rated ideas will be sent to each of the candidates for City Council and Mayor to see what they are willing to support. The results will all be posted online.

Location! Location! Location!

"We love the open space, imposing columns, high ceilings, and large windows with views of the skyline."

Azavea’s office is located in the Wolf Building on 12th and Callowhill Streets in what is now known as the Callowhill neighborhood. Callowhill consists, roughly, of the area north of Vine Street and Chinatown to Spring Garden Street and between Broad and 8th Street. Formerly the home to large-scale manufacturing and other industries, in recent years, many old factory buildings have been converted to loft-style apartments, condos and offices; to such a degree, that the neighborhood is also known as “The Loft District”.

Located in a one such loft on the 4th floor of the Wolf Building, we have been able to expand from a small area on the southeast corner of the building in 2002 to almost a quarter of the floor. We love the open space, imposing columns, high ceilings, and large windows with views of the skyline. Those ceilings have proven particularly fruitful as they have enabled our friend Dan Rose to create an elaborate, intriguing, and stark sculpture named, “Piton Project”. One of our programmers, David Zwarg, has also used the ceiling space as a canvas for a suspended map image from one of his projects using old business cards!

A few blocks away from the Reading Terminal Market and Chinatown, we can head to our favorite spots for a quick bite to eat at the market, Café Lift or Vietnam Restaurant (and wind down with some suds at a local microbrew, Independence Brew Pub). That’s what I call a nice location!
