This EnviroAtlas dataset categorizes land cover into structural elements (e.g. core, edge, connector, etc.). It depicts core areas of natural land cover, core fragmentation, and patterns of connectivity among core patches. Water is treated as missing in this dataset; waterbodies are masked out and not included in the analysis with the development and natural land cover classes. This dataset was produced by the US EPA to support research and online mapping activities related to EnviroAtlas. EnviroAtlas (https://www.epa.gov/enviroatlas) allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the contiguous United States. The dataset is available as downloadable data (https://edg.epa.gov/data/Public/ORD/EnviroAtlas) or as an EnviroAtlas map service. Additional descriptive information about each attribute in this dataset can be found in its associated EnviroAtlas Fact Sheet (https://www.epa.gov/enviroatlas/enviroatlas-fact-sheets).
This dataset is useful for green infrastructure applications, such as habitat suitability analyses. The overall goal of EnviroAtlas is to employ and develop the best available science to map indicators of ecosystem services production, demand, and drivers for the nation.

The software fills in missing data with foreground. This is primarily so that there are no edge effects along the map edge, but will also occur along water bodies if they are coded as missing. So if there are small areas of foreground in the vicinity of water, they are likely to be coded as a class other than islet, and they should be classified as islet according to the classification system. All other MSPA classes (core, edge, perforated, bridge, loop, and branch) can't occur unless there is core.

Connectivity data were derived using the GUIDOS 2.3 (Graphical User Interface for the Description of image Objects and their Shapes) raster image processing toolbox, which includes the Morphological Spatial Pattern Analysis tool (MSPA). Run GUIDOS 2.3 (forest.jrc.ec.europa.eu/download/software/guidos) on each piece, using 8 neighbor connectivity, 1 pixel edge width, transition and intext on.
