Abstract:
Data represent presence/absence for cedar decline is occurrence Cedar decline refers to the dying or decline of yellow-cedar (Chamaecyparis nootkatensis) forests in Southeast Alaska and is characterized by red or yellow foliage in trees currently dying, or by white-gray snags of old mortality. Mapped snags can be standing dead as long as eighty years. The data were collected via aerial sketch mapping techniques and recorded on 1:250,000 USGS base maps from 500-3000 foot above ground level(AGL) observations. Survey coverage has been most intense for forests adjacent to shorelines and waterways. Data are collected, refined and updated on an annual basis. This data represent not one year's mortality but the cumulative effect seen from the air.
Purpose:
The data were collected as an initial attempt to quantify the acreage affected by cedar decline. The data set gives general locations of cedar decline and provides land managers and researchers a starting point when considering the resource.
Supplemental_Information:
Data is collected through aerial surveys by aerial sketching of affected areas onto USGS 1:250000 topographic series maps. Sketched features were initially digitized into an Arc/Info coverage, then later edited using ArcView. Beginning in 2001 data and updates were digitally sketched in real time with GeoLink Software and a GPS for positional reference.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Attribute accuracy of forest damage is tested by visually comparing the source data with hard copy printouts or via a digital display. Survey specialist review processed data. Some data are ground checked but no formal accuracy reports are produced.
Logical_Consistency_Report:
Polygons were processed in ArcGIS. Overlapping polygons are not present.
Completeness_Report:
Data are collected, updated and refined on an annual basis. In any given year a fraction of the decline is flown and mapped or reevaluated if previously mapped.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Digital information is collected using sketching techniques with a remote aerial feature collection platform utilizing GPS positioning information. Polygons are sketched onto a computer screen or paper maps (USGS 1:250,000 hardcopy or digital maps). Background reference data is variable (commonly USGS DRGs, or satellite imagery).
Quantitative_Horizontal_Positional_Accuracy_Assessment:
Horizontal_Positional_Accuracy_Value: variable and not quantified
Horizontal_Positional_Accuracy_Explanation:
error is variable, contributed to by GPS error, spatial error in reference data and error associated with sketch mapping approximation

Overview_Description:
Entity_and_Attribute_Overview:
Polygons are coded with 1 in the decline column indicating decline is present. Beginning in 1999, polygons with significant red foliage are noted with a 1 in the yearly column. Beginning in 2010, features containing mixed species mortality and occurring in poorly drained, low volume, boggy areas will be coded with -1 in the decline column.
