Cool App: The Kansas airspace awareness tool

 

Back in February, the Kansas Department of Transportation announced its new Airspace Awareness tool, which they recently launched.

The software, funded by a grant from the Federal Aviation Administration, allows pilots to visualize data that is normally only presented in 2D charts or apps, rather than the 3D data available here.

According to the Aircraft Owners and Pilots Association, there were more than 2,000 airspace analyses performed in Kansas in 2010, some of which resulted in conflicts with local airspace. With this application in place, the system will alert users to contact the FAA in the event of any potential aispace conflicts with tall structures, such as wind turbines.

As of right now, Kansas is the only state with this kind of system in place, but if things go well I expect we’ll see other states introduce similar applications in the near future.

The Data Viz Challenge: can you make tax data exciting?

This time of year, everyone in the United States is starting to fill out—with varying levels of enthusiasm—our federal income tax forms. Yet, after we write our checks to the IRS, most of us don’t really know exactly where our money is going.

Fortunately, there’s a new online tool to help us find out. Last year, Andrew Johnson and Louis Garcia, two developers from Minneapolis, Minn., created a website called whatwepayfor.com that uses public data to estimate how our tax money is spent. You enter your income and filing status on the site, and it creates a formatted table of numbers showing your contributions to the federal budget—down to the penny:

We’re impressed by what the website uncovers. In 2010, for example, a married couple making $40,000 a year contributed approximately $14.07 to space operations, $6.83 to aviation security and $0.91 to the Peace Corps…and those are just a few of the hundreds of expenditures revealed on the site. As we spent time exploring all of these details, it got us thinking: how we could make the information even more accessible? So we created a simple interactive data visualization:

Click the image above to try the interactive version—it lets you drag the bubbles around, change the income level and so on. You can now look at the data in a new way, and it’s a little more fun to explore. Of course, there are lots of ways to visualize the data, and we’re very sure there are many talented designers and developers around the country who can do it even better than we have.

To make that happen, we’ve teamed up with Eyebeam, a not-for-profit art and technology center, to host what we’re calling the Data Viz Challenge. Andrew and Louis have built an API to let anyone access the data, so now you can choose how to display it. Could you create a better animated chart? Something in 3D? An interactive website? A physical display somewhere in the real world? We want you to show everyone how data visualization can be a powerful tool for turning information into understanding.

You can enter the challenge at datavizchallenge.org, where you’ll also find more information about challenge and the data. The challenge starts today and ends March 27, 2011, and is open to the U.S. only. The top visualization, as chosen by a jury, will receive a $5,000 award and a shout-out on the site and this blog. We’ll announce the shortlist on the week of April 11, and the winners on April 18, a.k.a. Tax Day.

If you’re a data viz enthusiast, we hope you’ll take a look at the data and build your own creative visualization. But even if you’re not, hopefully the results will help you appreciate what data visualization can do, and its usefulness in turning raw information—like federal income tax numbers—into something you can explore and understand.

Can I Have One NSDI with Some Confusion on the Side Please?

In this age of publish first, then filter, and instant gratification, it is easy to loose some of the real questions out of sight. The merging of Data.gov and Geodata.gov (yes, that is the plan) raises some questions that have gotten lost in the excitement from the last week.

Here are a couple observations on the subject that could be made by anyone who has been following the two sites over the past year(s):

  1. Geodata.gov harvests most of its content from over 300 other catalogs (visit the Geodata.gov Statistics tab and view the information on Partner Collections). Data.gov does not have this capability. These catalogs represent federal, state, and local government, academia, NGO, and commercial providers of geospatial resources (visit the same tab on Geodata.gov and view the information on Publisher Affiliations). Data.gov on the other hand focuses on content from the Executive Branch of the Federal Government. Where would the remaining content of Geodata.gov go? http://www.otherdata.gov?
  2. Geodata.gov focuses on FGDC+ISO metadata with the industry looking at migrating to the new North American Profile of ISO 191xx metadata. Data.gov has developed its own metadata specification and vocabulary that is quite different from this. Just look at a details page on Data.gov to confirm this. What is the position on this subject of FGDC and other federal agencies who have created standards-based metadata for many years?
  3. Geodata.gov has focused on the GIS analysts and first responders (check the original Statement of Work, I’m sure it’s online somewhere). Data.gov seems to focus on a different audience (although honestly it’s not entirely clear to me if that audience consists of developers or the general public. It’s a bit of both).
  4. Geodata.gov has supported a number of user communities in two ways:
    • by allowing them to create community pages with resources beyond structured metadata that are of interest to those communities. The content in these pages is managed by the communities themselves. How should Data.gov support these communities of interest?
    • by supporting community-oriented collections that group metadata from multiple source catalogs. Examples are RAMONA (the states’ GIS inventory), the Oceans and Coast Working Group (interested in all content in the US coastal zone), and Data.gov (actually, this is also configured as a collection in geodata.gov). These collections are exposed on the Geodata.gov Search tab and in the CS-W and REST interfaces to the catalog.Where would these collections end up after a merger of Geodata.gov and Data.gov?
    • Geodata.gov has created a Marketplace where those who are looking for data and those who have plans to acquire data can discovery each other and collaborate. A dating service of a different kind. While not specifically targeted at the masses, isn’t one of the key principles of NSDI to collaborate to reduce redundant investments?
  5. Geodata.gov has created a search widget that has been implemented by several agencies such as the State of Delaware that enables searching geodata.gov directly from the website and thus getting access to state and other geospatial resources covering the area of the state. This widget can mean significant cost savings for agencies as they don’t have to create their own clearinghouses. Will Data.gov provide such a role as well?
  6. Through FGDC CAP grants several tools were built that work against the Geodata.gov REST or CSW interfaces. I mentioned some of these capabilities and the links to these tools in my recent blog post. Merging Geodata.gov and data.gov would ideally not break these investments.

It would be nice to see the passion that was expressed over the last week be repeated, but now discussing some of these and other questions that affect the geospatial community at large.
