  1. Title: Solar Insolation, Minnesota] (2006-2012)

    Contributors:

    Summary: The Minnesota Solar Suitability Analysis attempts to provide solar insolation analysis for the entire State of Minnesota. As far as we are aware, it is the only project of its scale in existence; similar studies have been limited to metro areas or focus on rooftop insolation. The project's existence is feasible because of statewide, freely available aerial lidar coverage. And the commitment of the team to work long hours on this unfunded project. The project finds itself at the intersection of renewable energy, big data analysis, geospatial technology, and open data availability. This data provides a measure of incedent solar radiation as it is intercepted by the earth surface, or features (such as vegetation and buildings) standing above the earth surface. The data is intended to be used to assess the suitability of a site for solar panel (photovoltaic cell) installations. The analysis used to produce this dataset looks at geographic location, surface slope, surface aspect, and the effects of shading based on local topography and adjacent structures. A digital surface model was generated from raw LiDAR data. Then, using this DSM, an individual locations on a grid surface were assessed for the amount of direct and indirect radiation that reaches the surface. This analysis was conducted at a 1m resolution for the entire state of Minnesota.

  2. Title: Digital Surface Model [Minnesota] (2006-2012)

    Contributors:

    Summary: A 1m resolution digital surface model that was generated from raw lidar data. This dataset was an intermediate product of a process to model potential solar insolation for the state of Minnesota. The Digital Surface Model (DSM) was created to represent the terrain and all object present on that terrain. This included buildings, tree cover, roads, and other natural and human-altered landscapes. In effect, the DSM is a three dimensional representation of Minnesota. It was generated using a Streaming Delauney Triangulation process through rapidlasso's LAStools software package. In this process, triangles are iteratively generated using nearby lidar returns and values for each point are determined by extracting interpolated elevation from the surface of the triangle. The result is a 1 meter resolution raster covering the state. Lidar is a form of active remote sensing technology that uses light pulses, most commonly in the near-infrared wavelengths, to collected surface elevation data. A laser scanner, mounted in an aircraft and combined with high-accuracy GPS, collects light returns that are interpolated into a point cloud. Each point represents one return from a laser pulse. The laser pulse has the ability to penetrate vegetation, multiple laser returns can be gathered for each pulse including the returns from below the vegetation.The accuracy of lidar returns allow for a unique, multi-faceted analytical dataset. The first point returns can be used to interpolate a topology of Minnesota that models the objects (i.e. building, trees, etc) and geography resting upon the terrain. The lidar point files for the state of Minnesota used in the study were collected between 2006 and 2012 through an intergovernmental initiative with the primary object of providing improved elevation data for flood mapping. In some regions, existing lidar data was acquired and transformed to new state standards. Areas where data did not exist or could not be transformed, were collected by contracted vendors. The composite data forms a seamless coverage of the state with a resolutions of at least 1.5 meters. Refer to metadata.html for full details.

  3. Title: The Eagle Map of the United States Engraved for Rudiments of National Knowledge 1833 (Raster Image)

    Contributors:

    Summary: This layer is a georeferenced image of a map of the United States, originally created by James and Joseph Churchman and I.W. Moore in 1833. The states are shown in outline color with the eagle transparently sitting atop the nation.The historic map layers in the Google Earth Rumsey Map Collection have been selected by David Rumsey from his large collection of historical maps, as well as some from other collections with which he collaborates. All the maps contain rich information about the past and represent a sampling of time periods, scales, and cartographic art, resulting in visual history stories that only old maps can tell. Each map has been georeferenced by Rumsey, thus creating unique digital map images that allow the old maps to appear in their correct places on the modern globe. Some of the maps fit perfectly in their modern spaces, while othersgenerally earlier period mapsreveal interesting geographical misconceptions of their time. Cultural features on the maps can be compared to the modern satellite views using the slider bars to adjust transparency. The result is an exploration of time as well as space, a marriage of historic cartographic masterpieces with innovative contemporary software tools.

  13. Title: Primary Care Health Professional Shortage Areas, California, 2015

    Contributors:

    Summary: This polygon shapefile contains primary health care professional shortage areas (HPSAs) in California. On January 26, 2004, the California Healthcare Workforce Policy Commission (Commission) formally adopted a means to create the PCSA map. The process for identifying PCSAs uses the rule base listed below. In March, 2015, the OSHPD staff presented the Commission with information suggesting an update to the map to include current data on (1) physicians, (2) poverty and (3) population. Percent below Poverty Level (100%) Value Range Weighted Score 5.0 or Less 0 5.1 - 10.0 1 10.1 - 15.0 2 15.1 - 20.0 3 20.1 - 25.0 4 25.1 or Greater 5 (maximum) Physician-to-Population Ratio Value Range Weighted Score Lower than 1:1,000 0 1:1,000 to 1:1,500 1 1:1,500 to 1:2,000 2 1:2,000 to 1:2,500 3 1:2,500 to 1:3,000 4 Higher than 1:3,000 5 (maximum) * Any MSSA with a score of 5 or greater is defined as a PCSA. PCSAs are used as a means to help the Commission rank applications based on the number of program graduates and training sites inside areas of unmet need. PCSAs are the only consistently applied rule base to defining shortages of physicians, as the other designations are applicant based and require prior knowledge that a shortage might exist. This data is aggregated by Medical Service Study Area (MSSA) to obtain a count of primary care physicians by MSSA. Primary Care Shortage Areas are updated Annually and are used in the Song-Brown Grant Program for Family Medicine, Family Nurse Practitioner-Physician Assistant and Primary Care Residency programs. This update to data for the PCSA was approved by the California Healthcare Workforce Policy Commission on March 4, 2015. This layer is part of the Healthcare Atlas of California. This data for Primary Care Shortage Area (PCSA) was developed by the Office of Statewide Health Planning and Development's (OSHPD) Healthcare Workforce Development Division (HWDD). The data is used to support the following programatic areas: 1) encourage demographically underrepresented groups to pursue healthcare careers 2) identifies geographic areas of unmet need, and 3) encourages primary care physicians and non-physician practitioners to provide healthcare in medically underserved areas in California.

  15. Title: Census Zip Code Tabulation Areas, California, 2010

    Contributors:

    Summary: This polygon shapefile represents zip code tabulation areas (ZCTAs) for the state of California. These data were gathered from the 2010 Census demographics update and contain keys for ZCTAs, centroid coordinates, demographic fields for age, gender, race and ethnicity, and housing information including living quarters, institutionalized populations, households and housing units. For the 2010 Census, there were no “XX” or “HH” ZCTAs assigned. Only five-digit ZCTAs were produced, and large unpopulated areas were excluded from the delineations. For the 2010 Census, there is no wall-to-wall national coverage for ZCTAs. Large water bodies and unpopulated land area such as national parks were excluded from the 2010 delineations, and for this reason the Census 2010 product does not have complete national coverage. This dataset is intended for researchers, students, policy makers, and the general public 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 O'Neill, M. and California Office of Statewide Health Planning and Development.
