About the Author:  Sean Gorman founded FortiusOne in 2005 to bring location based analytics to the mass market. Sean brings over 10 years of experience at the forefront of the geospatial revolution as a researcher, practitioner, and entrepreneur at FortiusOne. Through both academic and entreprenurial efforts he has been working to make geographic data more accessible to the public since 1997 culminating in the creation of GeoCommons – a crowd-sourced repository of statistical data and social feeds that can be easily mapped, remixed and reused by non-technical users. Sean has been featured in media such as, Wired, Der Spiegel, ABC, Washington Post, Business 2.0, MSNBC, CBS and CNN. He also holds a PhD. From George Mason University in Public Policy where he was the Provost’s High Potential Scholar and was the recipient of the Fischer Prize. He has published dozens of articles on geographic data sharing and analysis, and authored the book Networks, Complexity and Security: The Role of Public Policy in Critical Infrastructure Protection.

We got such useful feedback from the last metadata post I thought I would add some screen shots of how it is starting to come together. Unfortunately we were not able to get all the suggestions in because of the time crunch hitting our release date, but please keep posting the feedback and we’ll work it in as we have more time.

The first screen shot is of the data details page, which contains the metadata information for the data set. In this case 2000 US Census data at the tract level for Alabama:

Here you can see the major elements we are capturing in a user friendly graphical lay out. One of the cool new bits is the system automatically calculates statistics when you upload the data. Being able to data mine and run statistics on the fly is one of the new developments we are particularly excited about.

All the metadata on the data details page is exposed as Dublin Core elements which should make them machine readable to the rest of the world:

Also there are links to FGDC and ISO 19115 metadata mappings which take you to simple text pages with the indicated information. We probably need another pass to get these completely correct, but the infrastructure is all in place to do so.

FGDC looks like this:

ISO 19115 looks like this:

Hopefully this will help make the data in GeoCommons useful to multiple geospatial work flows. We hope having the ability to get data out in shapefile, KML, and .CSV (spreadsheets) will create more cross fertilization between GeoWeb and GIS users. With some luck it can help get more geospatial data out to the public that has been difficult to access in the past. A couple of examples below.

US Census Tract Data for Alabama

Global Maritime Shipping Lanes

Zillow Neighborhoods and Shipping Lanes (just because it looked kinda cool)

Thanks again for the feedback from folks on the metadata and we’ll keep iterating on getting it spot on.
