It doesn’t take too much time to create the various fields, and as you can see in the examples, these are very similar with just a couple minor variations. The boundaries are available in the data catalog.
NYC Planning uses a seven character ID identifying tracts, the first digit is the borough ID and the remaining six are the Census Bureau defined tract ID which is good if joining to the tables created by NYC Planning only.
A new project – SchoolBook – will launch on September 7th, 2011 – a collaboration of the New York Times and WNYC, which will be a site offering daily news, data, and discussion about New York City schools, including customized pages for each of the 1,700 pubic schools and 800 private schools in the city.

NYPL has a new toy tool for rectifying digitized historic maps from their collection called the NYPL Map Rectifier.
After creating an account, browse through the various maps and collections, choose a map to rectify, clip or mask the image, and finally export out to either a KML (for Google Earth) or a WMS base URL for use in a GIS software. Some maps have the option to export into either PNG or TIF formats as well.
There is also a vectorize option for a few of the rectified maps (I didn’t see this option on most maps, I’m guessing because it’s still in beta). For these, the vector layers can be downloaded in several formats including shapefile.
NYPL has also created a site called Relief Map Warper and has uploaded maps for Haiti which after georeferencing, the maps will become available in Open Street Map for tracing, and also made available for use on the ground by relief workers. I highly recommend joining and helping out if you can.
We now have the latest version of the New York City Planning Tax Lot Layers; MapPLUTO 09 V1 is here and includes data updated through Spring of 2009. MapPLUTO models tax lots throughout New York City. This dataset represents a compilation of data from various government agencies throughout New York. The attribute data pertains to tax lot and primary building characteristics and information related to administrative and political districts for each tax lot in New York City. The underlying geography is derived from the Department of City Planning’s Tax Block and Tax Lot Base Map project.
The datasets are only available in the EDS lab during lab hours.

Another resource I did not mention but is well worth the time to check out is the NYPL Map Division blog which lists some of the unique maps and images available in their collection. Not only is this a valuable resource for maps related to NYC, but make sure to take a look at the attachments. Included in some of the posts are kml & kmz index files.
