Descriptive namePictometry 2018 Orthophoto Tiles
File namept18so39
Spatial domainEastern Pima County
AbstractPictometry uses a grid of approximately one-mile square areas called "sectors" that define a project area.

This pt18so39 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.

pt18sor3 displays individual 3-inch orthophoto tiles areas where each ortho tile covers a square area consisting of one-ninth of a full sector.

pt18sor9 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 2018 data "AZPIMA18-TILES-3INCH" and "AZPIMA18-TILES-9INCH" directories.
Known errors/qualificationsWhile 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.
