    Contributors:

    Summary: This layer is a georeferenced raster image of the historic, topographic paper map entitled: Missouri--Kansas : Kansas City quadrangle, Ed. of 1940, by the United States Department of the Interior, Geological Survey; topography by F.W. Hughes and C.A. Killian surveyed in 1934-1935. It was published by the Geological Survey in 1940. Scale 1:31,680. Covers Kansas City, Missouri, and portions of Kansas City, Roeland Park, Westwood, Westwood Hills, Mission Woods, and Mission Hills, Kansas. The image inside the map neatline is georeferenced to the surface of the earth and fit to the Missouri West State Plane Coordinate System NAD27 (in Feet) (Fipszone 2403). 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 is a typical topographic map portraying both natural and manmade features. It shows and names works of nature, such as mountains, valleys, lakes, rivers, vegetation, etc. It also identify the principal works of humans, such as roads, railroads, boundaries, transmission lines, major buildings, etc. Relief is shown with standard contour intervals of 10 feet and spot heights. This layer is part of a selection of digitally scanned and georeferenced historic maps from The Harvard Map Collection as part of the Imaging the Urban Environment project. Maps selected for this project represent major urban areas and cities of the world, at various time periods. These maps typically portray both natural and manmade features at a large scale. The selection represents a range of regions, originators, ground condition dates, scales, and purposes.

  5. Title: States, Northeast United States, 2007

    Contributors:

    Summary: This polygon shapefile contains state boundaries for the Northeastern United States The TIGER/Line Files are shapefiles and related database files (.dbf) that are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line File is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. States and equivalent entities are the primary governmental divisions of the United States. In addition to the fifty States, the Census Bureau treats the District of Columbia, Puerto Rico, and each of the Island Areas (American Samoa, the Commonwealth of the Northern Mariana Islands, Guam, and the U.S. Virgin Islands) as the statistical equivalents of States for the purpose of data presentation. In order for others to use the information in the Census MAF/TIGER database in a geographic information system (GIS) or for other geographic applications, the Census Bureau releases to the public extracts of the database in the form of TIGER/Line Shapefiles.

  7. Title: Relative Landslide Potential, Elk River Watershed, California, 1940-2000

    Contributors:

    Summary: This raster dataset represeting relative landslide potential within the Elk River watershed in Humboldt County, California. This layer contains five categories used to indicate potential for landsliding 91 = very low, 5 = very high). 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.

  8. Title: Planimetric Features - Curbs, Islands within Right of Way

    Contributors:

    Summary: Curbs and islands within the city rights-of-way. The data was develped by merging the 73 individual feature files of the Basemap into one citywide map. While the individual features files have not been updated since their development, the citywide file was updated to reflect changes along the Embarcardero corridor and along King St. Please note that the sidewalk widths (curbs) were derived from project working drawings and may not be as-builts conditions. There are plans by DPW to update the layers found in the features drawings.
