Title Elevation, slope, aspect, and vegetation classes for 1972 and 2012
Downloaded 9 times
Description Three sub-areas covering a total projected area of about 14 ha in the western Chugach Mountains of southcentral Alaska were digitized and attributed by vegetation class for 1972 and 2012 from a series of orthophotos. A 1m pixel digital elevation model provided elevation, slope, and aspect (DEM variables). This file contains the DEM attributes and vegetation classification for each 1m pixel.

Title 2000 random points for statistical modeling
Downloaded 3 times
Description 2000 random points across the three study sub-areas were selected for statistical modeling in binomial generalized linear mixed models. These points have digital elevation model (DEM) variables (elevation, slope, aspect, potential insolation in four seasons) and vegetation classifications for 1972 and 2012.

Title NeighborCommunities
Downloaded 12 times
Description NeighborCommunities is an ArcMap version 10.4.1 shapefile of line-features (SpatialLinesDataFrame in R) with four attributes giving the “Sub_area” of the study area, the length in km (“length_km”) of the line-feature, the functional class of the new, tall woody vegetation (“NewTWV”), and the bounding vegetation outside the polygon on a given poygon edge (“BoundVeg”). Projection is UTM zone6 with datum of WGS84. Please see NeighborCommunities_README.rtf for further details.

Title VegClass
Downloaded 8 times
Description VegClass is an ArcMap version 10.4.1 shapefile of polygon-features (SpatialPolygonsDataFramein R) with four attributes giving the “Subarea” of the study area, the area in ha (“area_ha”) of the polygon-feature, the functional class of the polygon in 1972 (“Veg1972”), and the functional class of the polygon in 2012 (“Veg2012”). Projection is UTM zone6 with datum of WGS84. Please see VegClass_README.rtf for further details.
