Title: Classification of Forest Fragmentation in North America, 1992
Contributors:- Raster data
- 2002
Summary: This raster layer is a grid map of North America including the Caribbean and most of Mexico in GeoTIFF format. The map layer is an excerpt from a global assessment of forest fragmentation (Riitters et al., 2000). Each pixel value represents an index of forest fragmentation for the surrounding 81 sq. km. The map layer was created by applying spatial algorithms to a 1 sq. km. resolution map of global land cover (Loveland and Belward 1997) known as NAIGBP1_2L, obtained from the USGS Center for EROS Distributed Active Archive Center (DAAC) as part of the Global Land Cover Characteristics database (GLCC)(Loveland et al. 1991, 1999). One of six categories of fragmentation was identified for each forested pixel in North America from the amount of forest and its occurrence as adjacent forest pixels within a 9x9 pixel (81 sq. km.) window surrounding the pixel on the original land-cover map. The map layer describes one aspect of forest fragmentation at one scale. The forest fragmentation index is designed to distinguish among types of fragmentation (e.g., edges on the interior versus the exterior of a forest patch) and it also reflects differences in the absolute amount of forest present. However, no distinction was drawn between "natural" and "human-caused" fragmentation. This is a revised version of the May 2002 map layer, with a corrected shoreline for Greenland. This map layer was previously distributed as the Forest Fragmentation Index Map of North America. This layer is part of the 1997-2014 edition of the National Atlas of the United States. These data were originally created as part of a global analysis of forest fragmentation and other land-cover patterns based on digital land-cover maps derived from remote sensing and produced by the Global Land Cover Characteristics project. The map portrays continental patterns at relatively coarse scale and is considered a first step towards quantifying forest fragmentation and its potential impacts on biodiversity at landscape-scale levels of biological organization. No responsibility is assumed by the National Atlas of the United States in the use of these data. Ritters, Kurt. (2002). Classification of Forest Fragmentation in North America, 1992.

Acknowledgment of the National Atlas of the United States of America and (or) the U.S. Geological Survey would be appreciated in products derived from these data. This layer is presented in the WGS84 coordinate system for web display purposes. Downloadable data are provided in native coordinate system or projection.

Title: Washington, D.C., 1855 (Raster Image)
Contributors:- Raster data

Summary: This layer is a georeferenced raster image of the historic paper map entitled: Colton's Georgetown and the city of Washington : the capital of the United States of America. It was published by J.H. Colton in 1855. Scale [ca. 1:25,750]. The image inside the map neatline is georeferenced to the surface of the earth and fit to the Maryland State Plane Coordinate System Meters NAD83 (Fipszone 1900). 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, block numbers, city wards, built-up areas, selected government buildings, parks, and more. Includes views: Smithsonian Institution -- The Capitol -- Washington Monument. 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.
