  12. Title: Tunis, Tunisia, 1910 or 1911 (Raster Image)

    Contributors:

    Summary: This layer is a georeferenced raster image of the historic paper map entitled: Plan de Tunis et ses environs, [dessine par J. Vanney]. It was published by C. Saliba aine between 1910-1911. Scale 1:8,000. Map in French.The image inside the map neatline is georeferenced to the surface of the earth and fit to the Universal Transverse Mercator (UTM Zone 32N, meters, WGS 1984) 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 drainage, roads, railroads and stations, selected buildings and built-up areas, shoreline features, parks, fortification, and more.This layer is part of a selection of digitally scanned and georeferenced historic maps from the Harvard Map Collection. These maps typically portray both natural and manmade features. The selection represents a range of originators, ground condition dates, scales, and map purposes.

  14. Title: Portland Air Toxics Solutions Data, 2012

    Contributors:

    Summary: "In 2009, DEQ created the Portland Air Toxics Solutions project to work with local communities to develop air toxics reduction strategies for the Portland region, including portions of Multnomah, Washington and Clackamas Counties" (www.deq.state.or.us/aq/toxics/pats.htm). These data represent block-group scale modeling of air toxics risks from a variety of sources (19 pollutants total), prepared in 2012 with model extrapolation to target year 2017. The study led to a number of priorities and ongoing management/policy discussions regarding Portland air quality. Data included here generally represent a ratio of pollutant concentration to ABC (ambient background concentration) for that pollutant, implying relative risk from each pollutant; see attribute file for details.
