The Geographic Inequalities of Broadband in Indiana


Indiana is participating in the National Broadband Program as a multi-year, multi-agency effort to map areas in the state that are currently served by the state’s 170+ broadband providers. The results from this will be integrated into a national broadband availability map, and will provide a solid foundation for future broadband deployment efforts at the state and national level.

“Broadband access supports our economy, attracts businesses, and enables Indiana to be globally competitive.  It improves the quality of life for Hoosiers through better communication and learning,” says Jim Sparks Indiana Geographic Information Officer regarding Indiana’s participation.

IT Is Suffocating GIS

In an article “Why Geo Will Embrace The Cloud in 2010” in Direction MagazineBrian Timoney of the The Timoney Group looks at the emerging cloud computing arena and poises the question, fad or not? Putting that question aside for the moment, part of Brian’s article really struck a chord with me – “IT is suffocating GIS.” As a former statewide GIS coordinator, I’ve seen all too many enthusiastic GIS professionals sucked down this path. Brian articulates something rarely discussed – issues like burn-out in the long since changed role of GIS managers. Are we properly preparing GIS professionals for this aspect of their GIS career? Here is an excerpt of Brian’s article: Read moreRead more

Visualizing the Grid: Interactive Web Map

NPR has produced a new interactive map of the U.S. energy grid and power sources. Included are several roll-over maps to see percent energy production by different states and by fuel type. It also includes an informative display of anticipated renewable (solar and wind) fuel sources incorporated into the grid over the next few decades. The maps are intuitive, well designed, and data sources are cited in the map’s footnotes. This is a good example of interactive map design for public education. It should serve as a terrific resource for educators to help students understand power production, renewable power supply, and power distribution in the U.S.
Visualizing the Grid

The interactive map is produced for NPR’s series, “Power Hungry: Re-Envisioning Electricity In The U.S.,” including over a dozen articles. One could easily imagine this series and maps being worked into the curriculum in middle through higher education, inviting students to explore questions about location, energy, and the future. From the site: “The U.S. electric grid is a complex network of independently owned and operated power plants and transmission lines. Aging infrastructure, combined with a rise in domestic electricity consumption, has forced experts to critically examine the status and health of the nation’s electrical systems.”

Keep Your Eye on the Geospatial Revolution Project

Whether you are a lone GIS technician or a large GIS company, education and outreach is an ongoing challenge for everyone in the geospatial industry. The Geospatial Revolution Project was announced about a month ago and I was overly impressed with the goals and production value. It was too bad the wait-time was going to be long for final production. Today I received news that the GRP team will release short video segments throughout the life of the project rather than waiting for them all at the end. They are starting today by making the trailer downloadable. This is a high-quality video that will be useful with the general public and decision-makers (and family members who haven’t got it yet ;) . Think about ways you might include the video clip in your community presentations, GIS day, school outreach, or the “About GIS” section of your website. See below for details – what a fantastic resource.

The Importance of Map Data Interoperability

Land Parcels and Flood Map Boundaries in the IndianaMap.org

Emergency Response Maps

After 9/11 and Hurricane Katrina, the lack of coordinated information and interoperable communications had tragic consequences. Citizens around the country demanded that government work together to correct otherwise avoidable problems.  Most people have heard about two-way radios in the debate over interoperable communications, but fewer realize the important role digital mapping plays in coordinated information and emergency response.  Digital mapping of government data, utilities, and infrastructure (collectively referred to as “spatial” or “geospatial” information) has become a cornerstone of information management and communication at all levels of government.   However, that spatial information is not yet coordinated across government agencies nor geographical regions.  When an electric crew from Indiana helps restore power after an ice storm in Atlanta, GA, the need for coordinated spatial information is great.  When a 911 cell phone call from an Illinois roadside gets routed to a dispatch center in Iowa,  the need for coordinated spatial information is great.  Similar examples of this need are remarkable and nearly limitless.

All Data Are Local

All data are local – and current sources of nation-wide (or world-wide) map data and services typically do not reflect authoritative (local government) sources of what is locally on the ground. Most sources lack vital information in less populated areas. Most sources take months or years with their data update cycles. (A notable exception is the growing openstreetmap.org, though not “authoritative” this “volunteered” map data making is a difference to emergency response around the world). Building a National Spatial Data Infrastructure (NSDI) has been a stated goal of the federal government and many geospatial professionals for over a decade.  In those years, many obstacles and delays have prevented the realization of a vision for our nations information infrastructure.  An infrastructure that promises to improve the health, safety and welfare of our citizenry, as well as provide more efficient use of tax payer dollars. By and large, technology is no longer the obstacle – it is human.  The obstacles reflect a resistance to change and fear of the unknown by policy-makers and stewards of local spatial data (How will this change how we do business? How will it affect the privacy of our citizens? Will it reveal we are doing things “wrong”? How will we fund it?  Knowledge is power – will we be giving that up by making our data available to others? Will our own data be used against us?).  But there is also danger in complacency of those responsible for building the NSDI.  As resistance to change takes a strong hold, the status quo becomes more and more comfortable.  Building the NSDI is hard (What if we can’t get cooperation? What if the funding runs short? What if we have technology glitches? How do we keep things running once it is built?). And making the decision to go – not to talk about doing it, but REALLY do it – is difficult.  This assertion is not meant to point fingers, rather it is an effort to remind us all of where our challenges lie – sometimes even within ourselves.  Institutional inertia is strong and personal risk is real for those who challenge long-standing institutional practices.  Those risks, and accompanied inertia, can make the realization of SSDIs and the NSDI even more distant.  As we look to our nations future, we must decide if the NSDI is really what we want (do we really want the NSDI, or do we really want to keep doing what we are doing, supporting our satisfied customers, keep a low profile, keep talking about the vision?).

We Just Decided to Go. (you can too)

Several states are taking the reigns and deciding to go by building complimentary Statewide Spatial Data Infrastructures (SSDIs) as a means to get at the NSDI.  Organizations like the National States Geographic Information Council are helping to put form on this approach.  As in business, there is no real status quo – there is either forward progress or we are slipping.  Indiana is one such state that can say “we just decided to go.”  Earlier this year, Indiana’s Geographic Information Officer, statewide coordinating council (www.igic.org), and handful of state agencies asked local governments across the state to participate in the IndianaMap (Indiana’s SSDI).  The road has been long and not without challenges (e.g., see news stories “Commissioners reluctant to give out mapping information“ and follow up story “Commissioners OK state’s mapping request”).  But deciding to go has resulted in 28 (of 92) counties signing on to participate within the first 6 months of the request, and over half the state’s population being covered.  While difficult, the result is definite progress toward coordinated information and interoperable communications for Indiana.

Those states who have committed to creating their own SSDIs have taken commendable steps to assure forward progress.  Without exception it has taken cooperation and strong leadership.  Those who just decided to go – let’s do this thing, and get’er done – are making real progress.  It would be impossible otherwise.

ScapeToad Cartogram Software

ScapeToad is an interesting, free, stand-alone cartogram software for Mac, Windows (and available platform independent). ScapeToad 1.1 is available for download under a GPL license.

Classical thematic mapping displays spatial patterns of theme or series data depicted on familiar reference maps of standard land-area polygons, which are typically distorted only by the selected projection. A cartogram is a map in which some thematic mapping variable – such as travel time or Gross National Product – is substituted for land area. The geometry or space of the map is distorted in order to convey the information of this alternate variable. There are two main types of cartograms: area and distance cartograms. To see examples, WorldMapper.org provides a nice collection of cartograms.

(from the ScapeToad website) “The visualization of social phenomena through classical thematic mapping often leads to unsatisfying representations… Cartograms are a well-known technique used to compensate for this inconvenience by breaking the link between statistical regions and their topographical areas. Consequently, this liberates one visual variable (that of polygon size) for a more relevant use, such as the representation of the relative social importance of these regions (usually measured by the size of their populations), while leaving intact their topological relations.”

Flex Projector for Interactive Creation of Map Projections

Flex Projector is an interesting new program for anyone who has ever been interested in map projections. The program provides a great hands-on interface for understanding more about how map projections work as well as to create your very own. Alpha 0.32 was released 1 April 2008 for Linux, Mac and Windows by Bernhard Jenny, Institute of Cartography, ETH Zurich and Tom Patterson, US National Park Service. According to their website (http://www.flexprojector.com) Flex Projector is a freeware, cross-platform application for creating custom world map projections. The intuitive interface allows users to easily modify dozens of popular world map projections—the possibilities range from slight adjustments to making completely new projections. Flex Projector is intended as a tool for practicing mapmakers and students of cartography. It took a couple tries to get the shape files to show up in the map window, but once they did I was off and running. Very ingenious application. I think this will become standard material for every introduction to cartography class out there. Its well worth a look for all professionals.
