GIS Data

X:/Drive

The X:/ Drive has a wealth of information primarily about New York City but also some other global locations.

All school computers should automatically be connected to the X:\ drive, but in the event it is missing, here are the steps to reconnect:

  • 1. Double click on MyComputer from your desktop. If you see the X:\ drive listed, then you will not need to reconnect.
  • 2. If it is not listed, click on the "Tools" pulldown menu and select "Map Network Drive".
  • 3. Expand the Architecture network, then scroll down and expand the New York network.
  • 4. Find the GIS folder, click on it and press OK. This returns you to the previous window where you select "Finish". The X:\ drive will open in a new window and you are now connected.

CAUTION!
Do no run GIS files from the X:\ drive. Running these files of the network will slow down your work (and everyone else's) and you will not be able to save any changes you make. It is recommended that you use ArcCatalog to find the files you wish to use and to then make a copy of them on your local scratch drive.

Shape files, the main GIS file format, are made up of a series of files. If you only copy the .shp— you
will not have the enitre file. Shapefiles are made up of .shp, .shx, .dbf, .sbx extensions. Copy everything that has the same name as the .shp to be sure that you have all the proper files.

The X:\ drive is organized into folders and subfolders as follows:
New York City Data
US Regional Data - Metropolitan Areas, with a Focus on the Northeast
State Data
NY Tristate
US Cities
International

COLUMBIA UNIVERSITY RESOURCES

The Digital Social Science Center (DSSC) in Lehman Library is the chief GIS Data Library for the overall University. They purchase and maintain their own collection of data, including historical datasets for New York City, and have Data Librarians who are able to help students in both finding and working with geospatial data.

The DSSC is located in Lehman Library in the School of International and Public Affairs (SIPA) at 118th Street and Amsterdam, and is open to all Columbia Students with a valid ID. Please refer to their website for hours.
