Description:

Abstract:

This data contains the flight lines that correspond with the Insect and Disease survey for 2002. The flight lines come from two sources, either hand drawn on the base maps in flight and then "heads up" digitized using USGS digital topographic maps as background or collected as a log file via GPS in GeoLink 6.1.7.1 maping software. The two types of information were appended in arcview as one layer, edge-matched.

Purpose:

This data was created to identify the actual flight line for the corresponding Insect and Disease aerial survey information. An estimate of area surveyed cooresponds to a two mile buffer from flight line

Supplemental_Information:

Procedures_Used: Most flight lines were collected via GPS. Only a section to western interior AK or minor gaps in the GPS log were digitized in ArcView. GPS flight lines were collected daily. These daily files and the "heads up" digitized lines were unioned together in Arc/View and attributes added. All zones were reprojected into ALBERS. Any corrections to the flight lines were made at this time. The A/V shapefiles were converted to an A/I cover using the export option in ArcGIS.

Process_Description:

Surveys were conducted by USFS FHP personnel and ADNR entomologist using Geo-Link software to capture flight line information from a GPS log. The flight lines for the western interior loop out of Anchorage Alaska were hand sketched at the time of capture on 1:250,000 scale USGS topographic-bathymetric series maps. Flight lines on the base maps are digitized into Arc/View using USGS 1:250,000 DRG's of the topographic-bathymetric series maps as background. The flight lines for the eastern interior south-central and Southeast Alaska are recorded at the time of capture into a Global Positioning System database. All files were Appended and projected in ArcView.
