  9. Title: United States of America by Bradford Scott 1816 (Raster Image)

    Contributors:

    Summary: This layer is a georeferenced image of a map of the United States in 1816. The original map appears in "North America; United States of America By Bradford Scott. 1816; South America, By Bradford Scott. 1816." 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: 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at a regional scale of mapping using ten sets of aerial photos combined with a compilation of earlier published and unpublished work.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.
