Description:
Abstract:
Data represent geographic area in which cedar decline is occurring. 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 from 500-3000 foot above ground level(AGL). 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 set 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 aspects of the resource.
Supplemental_Information:
Data is collected through aerial surveys by aerial sketching of affected areas onto USGS 1:250000 topographic series maps. Sketch work was initially digitized into an Arc/Info coverage, then later edited using ArcView. Beginning in 2001 data were sketch-digitized in real time with GeoLink Software and a GPS for signal fro positional reference. Parent files are now shapefiles.

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 an interactive display. Survey specialist review processed data. Some data are ground checked but not formal accuracy reports are produced.
Logical_Consistency_Report:
Polygons were processed in ArcGIS. Overlaping plygons 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. Prior knowledge of areas containing yellow-cedar or affected by the decline helps confirm or reject the accuracy of this data set.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Digital information collected using GPS for tracking and polygon placement accuracy. Polygons are sketched onto a computer screen or paper maps (USGS 1:250,000 hardcopy or digital maps). Background reference data is.
Quantitative_Horizontal_Positional_Accuracy_Assessment:
Horizontal_Positional_Accuracy_Value: variable and unquantified
Horizontal_Positional_Accuracy_Explanation:
error is a subjective quantity, contributed to by GPS error, error in background data spatial reference and sketch mapping approximation

Polygon information deliniated and attributed digitally at time of capture. USGS topographic-bathymetric series maps used as background with GPS real-time tracking. In some cases TM satellite imagery are used as reference background.
Process_Step:
Process_Description:
Data collected at time of capture. Transformed into ArcGIS 9.x for editing and correcting. Multiple data sets were merged and projected to Albers equal area (AK), NAD 27. Multipart polygons were converted to single part. Overlapping polygons were dissected.
