ClarkData Geospatial Data Server

The ClarkData Geospatial Data Server (ClarkData) provides geospatial data to the University of Michigan campus. Most publicly available data is not replicated on this server. The server contains data licensed for use by UM users, including current ESRI Data and Maps (10.1) and Landscan data (2000 to 2015).
You can access the read-only ClarkData space from most networked computers on campus, for example Clark lab computers, SITES computers, CAEN computers, faculty and staff computers, etc.. If you are on wireless or are off campus, you can do this only if you are using the VPN.
Step by step instructions for connecting to ClarkData are available at this "Connecting to the ClarkData fileserver" document, which requires UM affiliation to be viewed.
For more information, please email .
The most current versions of the street network dataset and address locators for the United States are at ESRI > Data_and_Maps_for_ArcGIS_10_1 > streetmap_na > data . If you have the space, performance of network analysis and geocoding will be better if you copy the data from the fileserver rather than just connecting to it.
