GeoCommons Metadata Implementation Screenshots
April 22nd, 2008by Sean Gorman
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.

I finally decided to write a comment on your blog. I just wanted to say good job. I really enjoy reading your posts.

Where did you get the Global Maritime Shipping layer? I have been looking for some thing like that for quite some time.

Hi Pablo -
The data comes from a project at Oak Ridge National Labs, and you can download the data from this page:
http://cta.ornl.gov/transnet/Intermodal_Network.html
It took me quite a while to track it down as well. Cool bit is the data has routing “to” and “from” nodes as well. I parsed out just the shipping lanes from the core data. The ORNL folks were doing some cool stuff with it building big intermodal commodity flow routing models. They are friendly folks that are happy to help out with the data. Hopefully Finder! will make locating all this squirreled away data a lot easier. Since one person’s data find can be shared with lot of folks. If you need the file as KML let me know and I can send it over.
best,
sean

Sean,
thanks for the note. I will check out the site you posted. But if it is not too much trouble, could you send me your KML file?
Thanks,
Pablo
