Researchers at the U.S. Forest Service Southern Research Station have utilized the National Land Cover Database (NLCD) to calculate a suite of land cover and forest fragmentation metrics at landscape scales. These datasets yield rich spatial information about urbanization, its effects on forests, and how urban areas interface and mix with rural, agricultural, and forest landscapes.The Forest Area Density (FDEN) map (Landscape Forest Density) illustrates the proportion of the landscape around a given forest area that is also forested. Areas with low forest density may be fragmented by agricultural land use and/or urban and exurban development. FDEN map is colored according to the amount of other forest in a surrounding...

The Landcover Mosaic map (LCM) can be used to answer the question: What is the mixture of agricultural/urban/natural landcover types surrounding a given land parcel?Researchers at the U.S. Forest Service Southern Research Station have utilized the National Land Cover Database (NLCD) to calculate a suite of land cover and forest fragmentation metrics at landscape scales. These datasets yield rich spatial information about urbanization, its effects on forests, and how urban areas interface and mix with rural, agricultural, and forest landscapes.The Landcover Mosaic Map (Landscape Mosaic Pattern) illustrates the mixture of agricultural, developed, and semi-natural land cover types within 15-hectare neighborhoods (about...

Using GIS, the SILVIS Lab at the University of Wisconsin-Madison calculated housing and population counts at the block group level with data from the decennial U.S. Census to produce a spatially explicit dataset for the conterminous U.S. This data can help to understand where on the landscape the most and the least dense populations of people live. Housing density can be used as an indicator of urbanization and land-use intensification.
