Description:
Abstract:
AP_TILES_POLY: 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.

A published revision of the Department Manual's Part 305: Departmental Science Effects, Chapter 3: Integrity of Scientific and Scholarly Activities (305 DM 3), effective December 16, 2014, is available online at http://elips.doi.gov/ELIPS/DocView.aspx?id=4056. Scholarly information considered in Departmental decision making must be robust, of the highest quality, and the result of as rigorous scientific and scholarly processes as can be achieved. Most importantly, it must be trustworthy. This policy helps us to achieve that standard (http://www.doi.gov/scientificintegrity/index.cfm)

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.
