    Contributors:

    Summary: This layer is a georeferenced raster image of the historic paper map entitled: An exact plan of His Majesty's great roads through the Highlands of Scotland, And. Rutherfurd delin. ; C. Mosley sculp. It was published in 1745. Scale [ca. 1:300,000].The image inside the map neatline is georeferenced to the surface of the earth and fit to the Europe Lambert Conformal Conic coordinate system. All map collar and inset information is also available as part of the raster image, including any inset maps, profiles, statistical tables, directories, text, illustrations, index maps, legends, or other information associated with the principal map. This map shows features such as drainage, cities and other human settlements, roads, selected buildings, shoreline features, fortification, troop dispositions of Jacobite and the Royal Government's troops for the Battle of Prestonpans, 1745, and more.

  2. Title: Block-level, non-work accessibility data for planned transitways in the Twin Cities [Minnesota]

    Contributors:

    Summary: Accessibility to grocery stores, primary healthcare, elementary, middle, and high schools by transit is measured for the Twin Cities. Census block-level minimum travel times to the first, second, third,...,tenth destination are calculated before and after incorporating services changes to the transit network. The transit network baseline includes the Green Line extension and Orange Line. Five planned transitways are evaluated against the baseline including the B Line and local route 21 changes, the D Line and local route 5 changes, the E Line and local route 6 changes, the Gold Line, and the Rush Line. The analysis is completed for four departure windows during the weekday. The report associated with this data aggregates across the Twin Cities metropolitan worker population and disaggregates by worker demographics. The data are organized by scenario then by departure window for a total of 28 scenarios. Each scenario has a Geopackage spatial file which is comprised of result layers for the five destination types studied. Travel times between blocks and X number of destinations are given in seconds. For example, this data answers the question "What is the minimum travel time on transit needed to reach 3 different grocery stores?"

  3. Title: Block-level accessibility data for managed lanes in the Twin Cities] (2019)

    Contributors:

    Summary: The data are provided in 4 ESRI shapefiles. The shapefiles are segmented by the analysis day of the week and departure time. The fields include the Census block-level 15-digit identifier (GEOID10), baseline accessibility, tier 1 managed lane scenario accessibility, their absolute difference, their percent difference. CRS EPSG: 4326 - WGS 84. Users should be able to map the cumulative job accessibility by automobile for 4 comparisons between baseline (general purpose lanes) and managed lanes (tier 1 corridors).

  5. Title: Access Across America Bike Data [Portland-Vancouver-Hillsboro, OR-WA] (2017)

    Contributors:

    Summary: This data was created as part of a study that examined the accessibility to jobs by biking in the 50 largest (by population) metropolitan areas in the United States, on low-stress and higher-stress streets via a Level of Traffic Stress analysis process. It is the most detailed evaluation to date of access to jobs by bike nationally, and it allows for a direct comparison of the bicycle accessibility performance of America's largest metropolitan areas. This data are part of a longitudinal study. Downloads are available for individual metropolitan regions, as well as states, in Geopackage format. Each individual ZIP file for a metropolitan area or state contains four ZIP-compressed Geopackage files of accessibility data, one for each of the four Level of Traffic Stress levels 1-4. A combined ZIP file containing the data for all metropolitan regions is also available in Geopackage format, and is labeled as "All Metropolitan Regions."
