Description:
Abstract:
ap_boundaries_tile: Polygon feature of aerial photography image coverage for BLM aerial photo projects in the states of Oregon and Washington. Individual polygons indicate the image footprint at the nominal scale of the photography. Imagery may be captured by linear scanner or by small scale single image sensors such as satellite. This is subject to update at a future point.
Purpose:
This feature is intended to facilitate the location and identification of BLM flightline data in Oregon and Washington for release to BLM district personnel, other agencies, and the general public.

Overview_Description:
Entity_and_Attribute_Overview:
Project boundaries are in a polygon feature class, created from digital point files.
Entity_and_Attribute_Detail_Citation:
The project boundary is created in ArcMap by buffering the flight lines of the project.  The buffered area around each flight line simulates the size of a line of overlapped photos, taking into consideration the scale of the photography and the length of the camera lens.  Since sidelap and endlap are required, the rows of flight line boundaries merge to form one project boundary with all interior boundaries lines dissolved.
