Geography: Datasets & Web Mapping

This is a restricted resource, accessible with UCSB netID, although there is some publicly available information.Esri's ArcGIS Online provides access to a wide variety of demographic, environmental, and historical information displayed via a map interface.  Datasets available include census information from many different countries, detailed consumer data for the United States (Tapestry Layers) and other countries, near real-time traffic information for several regions around the world, and global soil and elevation datasets.Users can create, save, and share web maps using their own data as well as that provided by Esri and the ArcGIS Online user community. Web Map Applications allow a series of maps and visualizations to be packaged as presentations that can be shared with the UCSB community and the general public.  See our ArcGIS Online page for additional information.

LandScan is produced by Oak Ridge National Laboratory.  The dataset is an estimate of population per 30 arc second pixel (better than 1 square kilometer) for the entire earth for the years 2000-2011.UCSB has access to this dataset via a web application, from inside of desktop GIS software, and as one large file available in the Map & Imagery Lab. The 2011 dataset includes population distributions changes based on the 2010 US Census and the 2011 Japanese earthquake and nuclear disaster.Methods of Access:There are three methods of access:A web application is available on campus and off-campus via the VPN or the proxy server. We strongly recommend the VPN; LandScan is much less stable via proxy.Desktop GIS users can access the dataset from inside your applications via these two URLs:WMSWCS Additional information is available directly from EastView.

Social Explorer provides access and mapping tools for current and historical census data and demographic information.
