  13. Title: Bath, England, 1787 (Raster Image)

    Contributors:

    Summary: This layer is a georeferenced raster image of the historic paper map entitled: An improved map of the villages, roads, farm houses, &c. five miles round the city of Bath : from an actual survey, made by Tho. Thorpe & others ; Ashby sculpt., Russell Court Covent Garden, London. It was published for Pratt & Marshall, Booksellers in Milsom Street. Scale [ca. 1:42,200]. The image inside the map neatline is georeferenced to the surface of the earth and fit to the 'British National Grid' 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 roads, drainage, selected public buildings, churches, farms, industry locations (e.g. mills, factories, mines, etc.), landcover, and more. Paper backing (verso) also shows several floor plans and facade views of houses in Ketten Strasse. This layer is part of a selection of digitally scanned and georeferenced historic maps from the Harvard Map Collection. These maps typically portray both natural and manmade features. The selection represents a range of originators, ground condition dates, scales, and map purposes.

  14. Title: Geologic Structures, Elk River Watershed, California, 1940-2000

    Contributors:

    Summary: This point shapefile represents geologic structures, such as quarries and bedding, within the Elk River watershed in Humboldt County, California. This dataset is the product of the Department of Conservation, California Geological Survey’s (CGS) investigation of landslides in the Elk River watershed. The 52 square mile study area is located in Humboldt County in northwestern California. The investigation was based on interpretation of 1940, 1941, 1948, 1954, 1962, 1965, 1984, 1988, 1996 and 2000 aerial photos, findings from CGS’s landslide mapping conducted in the early 1980s (Kilbourne, R.T. 1982-84, Manson, M. W. 1984), as well as other sources. Mapping was conducted at 1:24,000 scale. The resulting maps are titled “Geologic and Geomorphic Features Related to Landsliding, Elk River Watershed” (Plate 1) and “Relative Landslide Potential with Geologic and Geomorphic Features, Elk River Watershed” map (Plate 2). This study was conducted at a regional scale of mapping using ten sets of aerial photos combined with a compilation of earlier published and unpublished work. Other photo sets may reveal additional landslides. The regional nature of the study makes the data and maps, including the relative landslide potential zones, inappropriate as a substitute for site-specific analysis. CGS evaluated the geology, relative slope stability and geomorphic characteristics within the watershed, and compiled the digital geospatial data described in this document. This mapping and compilation is geared toward providing baseline geologic and geomorphic data to aid in responsible land management, as well as the development of watershed restoration projects, watershed management strategies, and watershed plans. Initial checking of attributes was conducted by the geologists who mapped the features. Limited field assessment of attributes was completed. The 'confidence' attribute indicates the geologist's level of certainty in a given feature (typically as viewed through a stereoscope). Peer reviewers and GIS staff conducted additional quality control. Because the attribute fields are designed to address various types of mapping products, and because some data is compiled from other sources, not all attribute fields are populated.

  16. Title: Narrow Landslide Features, Elk River Watershed, California, 1940-2000

    Contributors:

    Summary: This line shapefile depicts narrow landslide features within the Elk River watershed in Humboldt County, California. These landslides often occur as torrent tracts downstream of a debris slide source. All features in this layer are considered to be historically active.

    Contributors:

    Summary: This point shapefile depicts smaller active and dormant landslides within the Elk River watershed in Humboldt County, California. Features shown here represent landslides too small to delineate at 1:24,000 scale (typically less than 1/5 acre in area or less than 150 feet in length). These features are considered historically active (estimated to have moved within approxiamtely the past 150 years).
