    Contributors:

    Summary: This layer is a georeferenced raster image of the historic paper map entitled: Plan velo des environs de Paris : d'apres les cartes de l'Etat-Major et du guide Baroncelli, A. de Baroncelli. It was published by Librairie Neal in [1893]. Scale 1:125,000. Map in French.The image inside the map neatline is georeferenced to the surface of the earth and fit to the European Datum 1950, Universal Transverse Mercator (UTM) Zone 31N projected 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 bicycle routes, roads, railroads and stations, drainage, cities and towns, selected buildings, ground cover, and more. Includes distance notes in margins.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.

  3. Title: Geologic Units (Polygons): Geology of the Conterminous United States, 2005

    Contributors:

    Summary: This polygon shapefile shows the boundaries of geologic units within the United States. This layer is part of the Geologic Map of the United States, originally published at a scale of 1:2,500,000 (King and Beikman, 1974b). It excludes Alaska and Hawaii. These data depict the geology of the bedrock that lies at or near the land surface, but not the distribution of surficial materials such as soils, alluvium, and glacial deposits. This is a revised version of the April 2004 data set. This map complements the Generalized Geologic Map of Alaska, Hawaii, Puerto Rico, and the U.S. Virgin Islands by Reed and Bush. A geographic information system (GIS) allows combining and overlaying of layers for analysis of spatial relations not readily apparent in the standard paper publication. This layer is part of the 1997-2014 edition of the National Atlas of the United States. Conversion of the geologic map of the U.S. to a digital format was undertaken to facilitate the presentation and analysis of earth-science data. Digital maps can be displayed at any scale or projection, whereas a paper map has a fixed scale and projection. However, these data are not intended to be used at any scale finer than 1:2,500,000.

  14. Title: A global, self-consistent, hierarchical, high-resolution shoreline database

    Contributors:

    Summary: This collection consists of polygon shapefiles containing high-resolution shoreline data set amalgamated from three databases in the public domain. The data have undergone extensive processing and are free of internal inconsistencies such as erratic points and crossing segments. The shorelines are constructed entirely from hierarchically arranged closed polygons. The data can be used to simplify data searches and data selections or to study the statistical characteristics of shorelines and land masses. The individual polygons are available in 5 resolutions: full, high, intermediate, low, and crude. System requirements: Geographic Information Systems (GIS) software that reads ESRI shapefile format.

The image inside the map neatline is georeferenced to the surface of the earth and fit to the Massachusetts State Plane Coordinate System, Mainland Zone (in Feet) (Fipszone 2001). 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. These large scale fire insurance maps typically include: building footprints, building construction material (frame, brick, stone), building assessors areas, selected owner names, selected building functions, property boundaries, building street addresses, street names, railroads, fire hydrants, water main pipelines (with size in inches), sewers, and more. Building construction material is shown by colored shading. The index plate of the atlas includes an explanation of map features. This layer is part of a selection of digitally scanned and georeferenced historic fire insurance and land ownership atlases of Boston and Cambridge, Massachusetts from the Harvard Map Collection. The selection of scanned atlases represents a range of originators and ground condition dates (1873-1916).
