  1. 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.

  3. 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.

    Contributors:

    Summary: This multi-band raster data represents estimates of carbon opportunity cost. The data is captured at a resolution of 5 arcminutes over the global domain and is derived from data collected approximately over the past two decades (2000-2020). The pixel values measure estimates in tonnes of potential vegetation per hectare that are suppressed by pasturelands and present-day feed crops. The bands represent three estimates of carbon in potential vegetation: median, low (5th percentile), and high (95th percentile).

  18. Title: Springer Lab UAV Maize Phenotyping Project at UMN Saint Paul: 2018 and 2019 {Minnesota}

    Contributors:

    Summary: This dataset provides a valuable resource for evaluating the utility of unmanned aerial vehicles to collect phenotypic data in agricultural fields. Many flights throughout the growing season of a maize experiment were conducted and this dataset includes digital elevation models generated from images within these flights, the plot boundary shapefiles for plot identification, plant height values extracted following Tirado et al., 2019 procedure, hand measurement height values conducted following flights, and yield data for each plot. This maize experiment consisted of twelve hybrids planted at three different planting densities (low, medium and high) and two planting dates (early and late) across two years and therefore provides a valuable resource for evaluating how temporal data collected from UAVs can aid in assessing plant productivity. It can also be utilized to develop and test different protocols for plant height extraction from DEMs at different growth stages as the hand measurements can be used to test the accuracy. Files include digital elevation models for all flights of our maize field in the summer of 2018 and 2019, the plot boundary shapefiles, information on each plot including planting date and density and stand counts, yield data for all plots, and weather station data for both summers. More detailed info can be found in the readme file.
