  1. Title: Adjusted Urban Areas, California, 2010

    Contributors:

    Summary: This polygon shapefile represents adjusted urban area boundaries for California derived from the 2010 Census urban area boundaries, the preceding 2000 Caltrans urban area boundaries, and approved district and headquarters urban area adjustments. The three urban area boundaries were merged and smoothed to create the 170 adjusted urban area boundaries for California. This layer is part of a collection of GIS data created by the California Department of Transportation (Caltrans). The 2010 adjusted urban area file represents the current Federal Highway Administration (FHWA) approved Caltrans adjusted urban area boundaries in California. California Department of Transportation. (2013). Adjusted Urban Areas, California, 2010. California Department of Transportation. Available at http://purl.stanford.edu/jt346pj7452. The website about 2010 Adjusted Urban Areas: http://dot.ca.gov/hq/tsip/hseb/urban.html This data is made available to the public solely for informational purposes.Every reasonable effort has been made to ensure the accuracy of the data. There are no restrictions on distribution of the data by users. However, users are encouraged to refer others to the Department of Transportation’s GIS Data Library to acquire the data, in case updated data become available. This layer is presented in the WGS84 coordinate system for web display purposes. Downloadable data are provided in native coordinate system or projection.

  2. Title: National Highway System, California, 2013

    Contributors:

    Summary: This line shapefile contains the national highway system (NHS) of California as of 2013. Under Moving Ahead for Progress in the 21st Century (MAP-21), the enhanced NHS is composed of rural and urban roads nationwide serving major population centers, international border crossings, intermodal transportation facilities, and major travel destinations. The NHS includes the interstate system, other principal arterials, and border crossings on those routes (including other urban and rural principal arterial routes, and border crossings on those routes, that were not included on the NHS before the date of enactment of the MAP-21), intermodal connectors (highways that provide motor vehicle access between the NHS and major intermodal transportation facilities), and the Strategic Highway Network (STRAHNET), the network of highways important to U.S. strategic defense, including connectors to major military installations. On October 1, 2012 the existing National Highway System (NHS) was expanded to include all existing Principal Arterials (i.e. Functional Classifications 1, 2 and 3) to the new enhanced NHS. This layer is part of a collection of GIS data created by the California Department of Transportation (Caltrans). This dataset is intended for researchers, students, and policy makers for reference and mapping purposes, and may be used for basic applications such as viewing, querying, and map output production, or to provide a basemap to support graphical overlays and analysis with other spatial data.

  4. Title: LandScan Global Population Database 2013

    Contributors:

    Summary: This raster dataset contains population counts at 30 arc second resolution (1 km. or finer) for 2013. This release represents the fourteenth version of LandScan and succeeds all previous versions. Using an innovative approach with Geographic Information System and Remote Sensing, ORNL's LandScan is the community standard for global population distribution. At approximately 1 km resolution (30" X 30"), LandScan is the finest resolution global population distribution data available and represents an ambient population (average over 24 hours). The LandScan algorithm, an R&D 100 Award Winner, uses spatial data and imagery analysis technologies and a multi-variable dasymetric modeling approach to disaggregate census counts within an administrative boundary. Since no single population distribution model can account for the differences in spatial data availability, quality, scale, and accuracy as well as the differences in cultural settlement practices, There is also a layer file (lspop2012.lyr) for ArcGIS. This dataset is part of the LandScan global 2013. Developed for the U. S. Department of Defense. Allows for quick and easy assessment, estimation, and visualization of populations-at-risk. Bright, Edward A., Coleman, Phillip R., Rose, Amy N., and Oak Ridge National Laboratory. (2013) LandScan Global Population Database 2013. Oak Ridge National Laboratory, UT-Battelle, LLC. IMPORTANT: For correct population analysis using ESRI products assure that the following parameters are set:- Use ONLY Geographic, WGS84 projection parameters.- Spatial Analysis cell size is 0.008333333333333 (double precision)- Spatial Analysis extent should be set to an exact multiple of the cell size (for example 35.25, 35.50, 35.0)Converting (including on-the-fly projections) a grid to other projections or coordinate systems causes population cells to be re-sampled, and hence population counts will be incorrect.In ESRI ArcMap, load the LandScan grid first in order to maintain the original geographic (lat-lon) projection."The dataset has a spatial resolution of 30 arc-seconds and is output in a geographical coordinate system - World Geodetic System (WGS) 84 datum. The 30 arc-second cell, or 0.008333333 decimal degrees, represents approximately 1 km2 near the equator. Since the data is in a spherical coordinate system, cell width decreases in a relationship that varies with the cosine of the latitude of the cell. Thus a cell at 60 degrees latitude would have a width that is half that of a cell at the equator (cos60 = 0.5). The height of the cells does not vary. The values of the cells are integer population counts, not population density, since the cells vary in size. Population counts are normalized to sum to each sub-national administrative unit estimate. For this reason, projecting the data in a raster format to a different coordinate system (including on-the-fly projections) will result in a re-sampling of the data and the integrity of normalized population counts will be compromised. Also prior to all spatial analysis, users should ensure that extents are set to an exact multiple of the cell size (for example 35.25, 35.50, 35.0) to avoid 'shifting' of the dataset." --from the Oak Ridge National Laboratory LandScan Web site, Sept. 12, 2013.
