    Contributors:

    Summary: This layer is a georeferenced raster image of the historic paper map entitled: Map of the Boston & Maine Railroad : published by order of the Legislature of Massachusetts, showing its relative position & connection with other railroads, prepared by order of the Committee of Investigation ; Wm. P. Parrott, engineer ; George B. Parrott, del. It was published in July 1849 by W.C. Sharp's Lith. Scale [ca. 1:162,925]. Covers area from Portland, Me. to Boston, Mass. and west to Concord, N.H.The image inside the map neatline is georeferenced to the surface of the earth and fit to the USA Contiguous Albers Equal Area Conic projection (Meters). 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, or other information associated with the principal map. This map shows features such as roads, railroads, drainage, state, county and selected town boundaries, and more.This layer is part of a selection of digitally scanned and georeferenced historic maps of New England from the Harvard Map Collection.

  3. Title: Shellfish Management Areas, Northeastern United States, 2013

    Contributors:

    Summary: This polygon shapefile represents shellfish growing and classification areas for states in the northeastern U.S. including Connecticut, Maine, Massachusetts, New Hampshire, New York, and Rhode Island. Each state has their own method of classifying shellfish areas and these were evaluated in order to create a comprehensive classification system throughout the northeast region. The classification scheme used in this regional dataset is adapted from the National Shellfish Sanitation Program (NSSP) Guide for the Control of Molluscan Shellfish. Each feature includes information on the area name, classification type, state, source of the data, layer name from the data source, and the original state classification scheme. Additional fields which contained further information for individual datasets but did not conform to this characterization were not included. The Northeast Ocean Data Portal working group is continuing to work with shellfish coordinators in each state to improve the representation of these management areas and the timeliness of regional datasets. The data user is encouraged to read this and the metadata of each individual states’ source data carefully, as attribute details, and timeliness are not necessarily consistent among datasets used to develop this layer. Details of each state’s data source are described in the data processing section. The purpose of this dataset is to assist in ocean planning activities in the Northeast by representing the shellfish management and classification areas for the northeastern United States. Data represented here are from the most recent editions up to the dataset publication date. Data at this scale is suitable for use in generalized studies and local planning. Maine. Department of Marine Resources. (2013). Shellfish Management Areas, Northeastern United States, 2013. Northeast Ocean Data. Available at: http://purl.stanford.edu/qp739ty3462. Users must assume responsibility in determining the usability of this data for their purposes. Digital maps retain the accuracy of their source materials. The best use of data mapped at scales of 1:500,000 and 1:250,000 is in statewide planning and studies; at 1:100,000 in regional planning and studies; at 1:62,500 and 1:24,000 in detailed studies and local planning; and at 1:12,000 and 1:5,000 or larger scales in parcel level studies and detailed local planning. In the use of Maine GIS data, please check sources, scale, accuracy, currentness and other available information. Please confirm that you are using the most recent copy of both data and metadata from the Maine GIS Data Catalog. This layer is presented in the WGS84 coordinate system for web display purposes. Downloadable data are provided in native coordinate system or projection.

  4. Title: Map of the city of San Francisco showing the streets and the burnt area, 1906 (Raster Image)

    Contributors:

    Summary: This layer is a georeferenced image of a map of San Francisco showing the burned areas of San Francisco resulting the Earthquake in 1906. The original map appears in Carnegie Institution Of Washington. Atlas Of Maps And Seismograms Accompanying The Report Of The State Earthquake Investigation Commission Upon The California Earthquake Of April 18,1906. Andrew C. Lawson, G.K. Gilbert, H.F. Reid, J.C. Branner, A.O. Leuschner, George Davidson, Charles Burckhalter, W.W. Campbell. Washington, D.C. 1908. This project traces the history of urban planning in San Francisco, placing special emphasis on unrealized schemes. Rather than using visual material simply to illustrate outcomes, Imagined San Francisco uses historical plans, maps, architectural renderings, and photographs to show what might have been. By enabling users to layer a series of urban plans, the project presents the city not only as a sequence of material changes, but also as a contingent process and a battleground for political power. Savvy institutional actors--like banks, developers, and many public officials--understood that in some cases to clearly articulate their interests would be to invite challenges. That means that textual sources like newspapers and municipal reports are limited in what they can tell researchers about the shape of political power. Urban plans, however, often speak volumes about interests and dynamics upon which textual sources remain silent. Mortgage lenders, for example, apparently thought it unwise to state that they wished to see a poor neighborhood cleared, to be replaced with a freeway onramp. Yet visual analysis of planning proposals makes that interest plain. So in the process of showing how the city might have looked, Imagined San Francisco also shows how political power actually was negotiated and exercised. California.
