Scope and Content The Digital Sanborn Maps of Milwaukee 1894 & 1910 brings online 2 fire insurance atlases featuring detailed color maps of Milwaukee. Produced by the Sanborn Map Company, the 1894 atlas includes four volumes, consisting of 450 map sheets and the 1910 atlas includes eight volumes, consisting of 830 map sheets. Sanborn maps were designed to assist fire insurance agents with insuring property. Produced for over 12,000 urbanized areas in the United States, Sanborn maps have been described by the Library of Congress as "the single most important record of urban growth and development in the United States during the past one hundred years." Sanborn maps are excellent historical resources for academic, professional and personal needs. Planners, preservationists, genealogists, architects, urban geographers and historians are among those who will enjoy using this digital collection. Some features found on Sanborn fire insurance maps include: construction material of dwellings, commercial buildings, and factories, fire walls, windows, doors, style and composition of roofs, wall thickness, cracks in exterior walls, elevator locations, building uses, sidewalk and street widths, layout and ownership names, property boundaries, distance between buildings, house and block numbers, location of water mains, hydrants, piping, wells, cisterns, and fuel storage tanks. The Digital Project The digital collection provides access to the Sanborn maps of Milwaukee of 1894 and 1910 in two versions: as PDF files and as high resolution images in the JPEG2000 format with corresponding searchable records. The maps were scanned at 300 dpi resolution using a large format scanner Colortrac 4280 in the American Geographical Society Library. Digital master files in the TIFF format serve as a source for JPEG2000 images presented in CONTENTdm software. High resolution images in CONTENTdm software correspond to individual map sheets. Through zooming and panning technology, map images can be seen in great detail. The records were built with CONTENTdm digital media management software using Dublin Core metadata. The collection in CONTENTdm is fully searchable and users can search maps and indexes by street names, names of businesses, or names of historical landmarks. In addition, users may search the modern Google Earth map interface to link to sheets within the atlas. The PDF versions were created to provide access to atlases by volume. Users can browse the volumes, but this version is not keyword searchable. The PDF versions can be downloaded for use.
