NYC neighborhood changes mapped with aerial imagery, historic land use data

Our team at the CUNY Graduate Center has enhanced the OASISnyc.net mapping site with new data and features to visualize neighborhood change across the city. On the eve of the 10th anniversary of 9/11, the updates help provide context for the transformation taking place in lower Manhattan, as well as in other key areas of the city.

I’ve only included some of the highlights below. Our OASIS wiki has more details plus screenshots and other examples.

2010 Aerial Imagery

We’ve added new aerial imagery, thanks to the NYS GIS Clearinghouse. Now you can view overhead images from 2010 (as well as 1996, 2004, 2006, and 2008) throughout New York City and Long Island. (The 1996 imagery is from NYC DoITT, 2004 is from USGS, and the other years are from the NYS GIS Clearinghouse).

For example, you can see what the World Trade Center site looked like from above in 1996, and then in 2006, and more recently in 2010. The overhead images show clearly how the building footprints are reflected in the memorial plaza fountains now under construction.

Visualize Aerial Photo Changes like a Timelapse Movie

We’ve also changed the way you can view the imagery over time. Now you can move the aerial timeline slider across years to transition from one year to the next, creating the effect of a timelapse movie within the OASIS map.

You can move the slider as slow or as fast as you’d like.

A good example of the new timelapse feature is Shea Stadium (now Citi Field) in Queens. The images below illustrate the transition in recent years.

Land Use Changes Citywide

Since 2010, OASIS has provided the ability to display historical land use patterns (for 2003 through 2009). This gives you the ability to easily see how patterns have changed in key areas of the city.

In lower Manhattan, the area around the World Trade Center site has changed substantially in the past 10 years. Of course reconstruction is underway at the WTC site itself, but the surrounding community has become much more residential. The land use maps below from OASIS visualize some of these changes (yellow and orange are residential properties, brown is vacant, and light red is commercial).

The maps below highlight the changes from commercial office buildings to residential towers, such as the block between Broad and Hanover streets & Wall and Exchange streets — especially the JP Morgan Building at 15 Broad St and the National City Bank Building at 55 Wall St.

More Community Data

The latest example of linking mapped information from grassroots groups is the layer of skate parks in the city by longtime OASIS partner Open Road of NY. (The OASIS community mapping effort is based on Google’s new Fusion Tables service; more info here.)

Here’s the link to the map on OASIS, and the original Google map from Open Road.

We’ve also added the locations of stalled development sites across the city (based on a map from Crain’s New York Business), and the city’s hurricane evacuation centers (more on that here).
