Descriptive name		Pictometry 2016 Orthophoto Tiles
File name		pt16so39
Spatial domain		Eastern Pima County
Abstract		Pictometry uses a grid of approximately one-mile square areas called "sectors" that define a project area. This pt16so39 layer was made by appending the two original Pictometry 3-inch and 9-inch individual photo areas described below to make one layer. A new RESOLUTION field with '3-inch' or '9-inch' was added. pt16sor3 displays individual 3-inch orthophoto tiles areas where each ortho tile covers a square area consisting of one-ninth of a full sector. pt16sor9 displays individual 9-inch orthophoto tiles areas where each ortho tile covers a square area consisting of one full sector. The tiles defined by this layer represent the areas covered by each of the 3-inch and 9-inch resolution orthophotos in JPG format in the Pictometry 2016 data "AZPIMA16-TILES-3INCH" and "AZPIMA16-TILES-9INCH" directories.
Known errors/qualifications		While these Pictometry sectors and ninth-sectors are approximately 1 mile and 1/3 mile square, they are not based on PLSS sections and are offset considerably from the PLSS section grid.
