  1. Title: Dry Nitrogen Deposition: San Francisco Bay Area, California, 2007

    Contributors:

    Summary: This raster dataset depicts dry nitrogen deposition for the nine county San Francisco Bay Area Region, California. Dry nitrogen deposition is the input of reactive nitrogen from the atmosphere into the biosphere as dry deposition, or acidic gases and particles. An overabundance of nitrogen in the atmosphere and environment has deleterious effects on the biosphere. The source data was produced by the Center for Conservation Biology at the University of California, Riverside (UCR) and is based on a nitrogen deposition model data developed by the UCR College of Engineering Center for Environmental Research and Technology (CE-CERT). Text values from the dry nitrogen deposition model were processed to provide the values stored in this raster. The model used here is total annual deposition and based on data from calendar year 2002. These data are considered useful in studying the effect of nitrogen deposition on aspects of complex biological systems. This dataset was developed/compiled for use in the San Francisco Bay Area Upland Habitat Goals Project, a Project used to identify a Conservation Lands Network (CLN) for biodiversity preservation to inform conservation investments and lasting cooperative conservation partnerships. The Conservation Lands Network GIS Database is the primary output of the Project. The data depicts the spatially explicit CLN that is recommended for the nine county San Francisco Bay Area Region, California.

  2. Title: Total Nitrogen Deposition: San Francisco Bay Area, California, 2007

    Contributors:

    Summary: This raster dataset depicts a geography of nitrogen deposition for the nine county San Francisco Bay Area Region, California. Nitrogen deposition is the input of reactive nitrogen from the atmosphere into the biosphere as wet and dry deposition, either acidic gases and particles or acidic rain, fog and snow, respectively. An overabundance of nitrogen in the atmosphere and environment has deleterious effects on the biosphere. The source data was produced by the Center for Conservation Biology at the University of California, Riverside (UCR) and is based on a nitrogen deposition model data developed by the UCR College of Engineering Center for Environmental Research and Technology (CE-CERT). Raster values from both dry and wet nitrogen deposition models were added to provide the values stored in this raster. It represents total annual deposition of all forms of nitrogen for the calendar year 2002. These data are considered useful in studying the effect of nitrogen deposition on aspects of complex biological systems. This dataset was developed/compiled for use in the San Francisco Bay Area Upland Habitat Goals Project, a Project used to identify a Conservation Lands Network (CLN) for biodiversity preservation to inform conservation investments and lasting cooperative conservation partnerships.

    Contributors:

    Summary: This layer is a georeferenced raster image of a map of the United States originally created by Matthew Carey and engraved by William Barker. The original paper map was published in Carey's American Pocket Atlas (Lang and Ustick, 1796, 1st ed.), which includes 19 maps showing roads, rivers, and boundaries for the different states and territories of the U.S. 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. A scanned version of this map was georeferenced by the Center for Spatial and Textual Analysis (CESTA) at Stanford University. This map is part of a selection of georeferenced historic maps from the David Rumsey Map Collection at Stanford University.This map provides an historical perspective of the cultural and physical landscape during this time period. The wide range of information provided on these maps make them useful in the study of historic geography. As this map has been georeferenced, it also can be used as a background layer in conjunction with other GIS data.

  19. Title: Massachusetts Iowa basic Skills Test Scores

    Contributors:

    Summary: This datalayer displays a polygon coverage for Massachusetts towns with associated attribute data on the average scores on the 'Iowa Test of Basic Skills' (ITBS) for children attending schools in towns includes inthe MAPC Region. The ITBS is a series of general achievement tests for grades three through eight. Along with others, such as the Comprehensive Tests of Basic Skills and the Stanford Achievement Test Series, they are designed to measure how well a student has learned the basic knowledge and skills that are taught in elementary and middle schools, in such areas as reading and mathematics This dataset was originally prepared and distributed by the Metropolitan Area Planning Council (MAPC). It was published as part of the Massachusetts Electronic Atlas database in 2001. The Massachusetts Electronic Atlas (MEA) was a collaborative project to provides access, via the Internet, to data about the Commonwealth, its thirteen regional planning agency districts and 351 cities and towns. This dataset is now only available via The Harvard Geospatial Library. The Metropolitan Area Planning Council (MAPC) is a regional planning agency representing 101 cities and towns in the metropolitan Boston area. Created by an act of the Legislature in 1963, it serves as a forum for state and local officials to address issues of regional importance. As one of 14 members of the Metropolitan Planning Organization (MPO), MAPC has oversight responsibility for the region's federally funded transportation program Stretching west from Boston to include most of the communities inside the I-495 corridor, the MAPC planning area consists of 22 cities and 79 towns. Coastal communities, older industrial centers, rural towns, and modern cities are represented within the 1,422 square miles that comprise the MAPC region.
