  12. Title: Lisbon, Portugal, 1808 (Raster Image)

    Contributors:

    Summary: This layer is a georeferenced raster image of the historic paper map entitled: Grundress von Lissabon 1808, E. Muller jun sc. It was published in [1808]. Scale [ca. 1:34,000]. Covers a portion of Lisbon, Portugal. The image inside the map neatline is georeferenced to the surface of the earth and fit to the European Datum 1950, UTM Zone 29N 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, built-up areas and selected buildings, fortification, and more. Relief is shown by hachures. Includes location map covering Spain and Portugal and inset view: Ansicht von Lissabon. 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.
