Washington, 3D City

20080717_RFK-GoogleEarth.jpgA year ago, we geeked out over the possibility that Google Maps would soon include its Street View feature in D.C. area maps. Google has indeed collected Street View imagery for Washington, DC, but still no launch date has been announced for the feature.

In the meantime, we've got something a little cooler – or at least something with a comparable "gee whiz, that's neat" factor – to tide us over. On Tuesday, Google announced that the first participants in the Cities in 3D program released their building models on Google Earth; D.C. is among the participating cities.

As part of the project, over 84,000 buildings in the District were rendered in 3D. Some buildings – mostly notable landmarks such as the National Cathedral, Union Station, R.F.K. Stadium and the White House – are rendered with a photorealistic façade. The effect makes the city look like something out of "The Sims." Clicking on one of the photorealistic structures brings up an information bubble about the building.

There are some random discrepancies here and there. For instance, buildings on a cluster of four blocks north of Lincoln Park are missing. Nationals Park doesn't appear in Google Earth at all, but buildings the ball field displaced do. And mine is the only garage on my block that wasn't rendered, which frankly I'm not complaining about.

The data was generated by the Office of the Chief Technology Officer's Geographic Information Systems (GIS) program. On Google Earth's Lat-Long blog, GIS Manager Barney Krucoff listed four reasons why D.C. participated in the project. Chief among them is the D.C. government's belief that "data created with public funds should be available to the public." Google Earth is also a cost effective way to allow D.C. government employees to not only access and use the gathered data, but also to connect with residents.

If 3D models aren't enough, one can download additional geospatial layers for Google Earth from the GIS Data Clearinghouse/Catalog. This can be particularly useful if you want to map out Metro station entrances; libraries; ZIP codes; and my personal favorite, no-fly zones.

Ooh, RKF with a baseball field! How 2007 of them.

 

I thought we were 3rd world city? Hey da ditty.

 

wow, i'm impressed with this! i know the GIS layers have always been available to the public, but you needed arcview or some other GIS program, which i'm lucky enough to have access to at work, but a lot of the public does not.

creating KMLs makes this much much more accessible to the public. bravo, dc gis!

 

GIS FTW!!!

 

IMGoph there was a free version ArcView. It doesn't seem to exist anymore, though.

 

yeah, i remember that politburo, but it sucked. zero functionality.

 

I've seen those Street View camera cars driving around. I try not to pick my nose or anything when they go by because I don't want to be immortalized on the tubes that way. I'd rather be known for the marauding and pillaging, etc.

 

The DC GIS Data Clearinghouse will not let you download the 3D building Google KML set, you have to get it directly from them office of the CTO.

For downloading the other datasets [http://dcatlas.dcgis.dc.gov/catalog/] they ask you to provide a phone number and an email address... why would they need a phone number, of all things?

One of their datasets, the Neighborhood Composition diagram is somewhat interesting -- they categorize areas of town as
- Distressed (including all of Gallaudet, parts of Trinidad,
- Emerging (including North of H street, Sirsum Corda, Shaw/Howard)
- NA (federal space)
- Stable (including the area SE of MN ave in Anacostia, much of which is parkland)
- Transitioning (including around Arena Stage, all of Judiciary Square, and one giant block waving around 16th street up to Rock Creek Park).

I don't know if it is optimistic that most of the District outside of NW is shown in that map as Emerging... is it naive instead?
