Each pixel value represents an index of forest fragmentation for the surrounding 590.49 ha.(81 x 81 pixel) analysis window. The dataset was created by combining published maps of forest area density, and forest area connectivity, from the National Land-Cover Pattern Database (NLCPD), and a published map of land-cover from the Multi-Resolution Land Characteristics (MRLC) Consortium. One of twelve categories of fragmentation was identified by using a model similar to Riitters et al. (2000). The data set 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. No distinction was drawn between "natural" and "human-caused" fragmentation.</PRE> <SCRIPT>fix(original)</SCRIPT> </DIV> <DIV> <DT><I>Purpose:</I></DT> <PRE ID="original">These data were created as part of a national analysis of land cover pattern. A series of derived maps (different indices, different window sizes) is available. They are proposed for consideration by landscape analysts, as independent variables (e.g., covariates, stratification rules), and as "context" information for finer-scale investigations, for example field plots. Caveats include: Maps in this series are naturally correlated since all came from one map. No warranty or claim is made of the utility of this map for any particular purpose, this is considered to be a research dataset. The forest fragmentation index map portrays considers only forest versus non-forest cover types.</PRE> <SCRIPT>fix(original)</SCRIPT> </DIV> </DL> </DD> <DT><I>Time_Period_of_Content:</I></DT> <DD> <DL> <DT><I>Time_Period_Information:</I></DT> <DD> <DL> <DT><I>Range_of_Dates/Times:</I></DT> <DD> <DL> <DT><I>Beginning_Date:</I> 1988</DT> <DT><I>Ending_Date:</I> 1993</DT> </DL> </DD> </DL> </DD> <DIV> <DT><I>Currentness_Reference:</I></DT> <PRE ID="original">Dates of satellite imagery.</PRE> <SCRIPT>fix(original)</SCRIPT> </DIV> </DL> </DD> <DT><I>Status:</I></DT> <DD> <DL> <DT><I>Progress:</I> Complete</DT> <DT><I>Maintenance_and_Update_Frequency:</I> Irregular</DT> </DL> </DD> <DT><I>Spatial_Domain:</I></DT> <DD> <DL> <DT><I>Bounding_Coordinates:</I></DT> <DD> <DL> <DT><I>West_Bounding_Coordinate:</I> -76.594174</DT> <DT><I>East_Bounding_Coordinate:</I> -73.773542</DT> <DT><I>North_Bounding_Coordinate:</I> 42.617847</DT> <DT><I>South_Bounding_Coordinate:</I> 38.322510</DT> </DL> </DD> </DL> </DD> <DT><I>Keywords:</I></DT> <DD> <DL> <DT><I>Theme:</I></DT> <DD> <DL> <DT><I>Theme_Keyword_Thesaurus:</I> None</DT> <DT><I>Theme_Keyword:</I> pattern</DT> <DT><I>Theme_Keyword:</I> landcover</DT> <DT><I>Theme_Keyword:</I> landscape</DT> <DT><I>Theme_Keyword:</I> forest</DT> <DT><I>Theme_Keyword:</I> fragmentation</DT> </DL> </DD> <DT><I>Place:</I></DT> <DD> <DL> <DT><I>Place_Keyword_Thesaurus:</I> None</DT> <DT><I>Place_Keyword:</I> Delaware</DT> <DT><I>Place_Keyword:</I> Maryland</DT> <DT><I>Place_Keyword:</I> New Jersey</DT> <DT><I>Place_Keyword:</I> New York</DT> <DT><I>Place_Keyword:</I> Pennsylvania</DT> </DL> </DD> </DL> </DD> <DT><I>Access_Constraints:</I> None</DT> <DIV> <DT><I>Use_Constraints:</I></DT> <PRE ID="original">None.

Each pixel value represents a continuous [0,1] variable with byte values in [1,255] with zero (0) representing a missing value. Larger values represent more forest and higher connectivity, respectively. Note that the two maps were derived from the MRLC land cover map, and that "woody wetland", and "upland forest" were considered to be "forest" when computing the index values in Edition 4 of the NLCPD. Also note that the MRLC types "water", "ice", and "bare rock" were considered as missing values for the density and connectivity measurements. This means that fragmentation was not "caused" by those land cover types in this analysis; they were ignored in calculations. Land cover was obtained from the MRLC in binary format. Each pixel value represents one of 21 land-cover types in [1,92] with zero (0) representing a missing value. The three images were overlaid, pixel by pixel, using an in-house software tool named FRAGCL.C to assign a fragmentation index value. The classification model identifies twelve fragmentation categories, two missing value categories, and one water/rock category: &gt;(0) Missing_1, if MRLC is missing (0). &gt;(1) Edge_1, if FRAG81 &gt;= FDEN81, and if 153 &lt; FDEN81 &lt; 230. &gt;(2) Perforated_1, if FRAG81 &lt; FDEN81, and if 153 &lt; FDEN81 &lt; 230. &gt;(3) Transitional_R, if 101 &lt; FDEN81 &lt; 154, and &gt; if FRAG81 &gt;= FDEN81. &gt;(4) Transitional_L, if 101 &lt; FDEN81 &lt; 154, and &gt; if FRAG81 &lt; FDEN81. &gt;(5) Patch_R, if FDEN81 &lt; 103 and if FRAG81 &gt;= FDEN81. &gt;(6) Patch_L, if FDEN81 &lt; 103 and if FRAG81 &lt; FDEN81. &gt;(7) Interior, if FDEN81 = 255. &gt;(8) Non-forest, if FDEN81 = 1. &gt;(9) Water/rock, if MRLC is either water(11), ice(12), or bare rock(31). &gt;(10) Missing_2, if FRAG81 is missing (0) and FDEN81 is &gt; not missing (&gt; 0). &gt;(11) Edge_2, if FRAG81 &gt;= FDEN81, and if 242 &lt; FDEN81 &lt; 255. &gt;(12) Perforated_2, if FRAG81 &lt; FDEN81, and if 242 &lt; FDEN81 &lt; 255. &gt;(13) Edge_3, if FRAG81 &gt;= FDEN81, and if 229 &lt; FDEN81 &lt; 243. &gt;(14) Perforated_3, if FRAG81 &lt; FDEN81, and if 229 &lt; FDEN81 &lt; 243. For pixels that are have defined values for land cover, forest area density, and forest connectivity, the classification model partitions the two-dimensional space defined by FRAG81 and FDEN81 into twelve fragmentation categories. The category is then changed to water/rock if the MRLC land-cover map is water, ice, or bare rock. Note that the critical values 102 and 153 represent the proportions 0.4 and 0.6, respectively, before the FDEN81 and FRAG81 values were converted from continuous [0,1] values to integer [1,255] values. The "undetermined" category in Riitters et al. (2000) is considered to be "edge". The "header file" information for the derived map is as follows. This information is needed for some image import filters.
