Descriptive namePictometry 2020 Orthophoto Tiles
File namept20so39
Spatial domainEastern Pima County
AbstractPictometry uses a grid of approximately half-mile square areas called "cells" that define a project area. Pictometry sometimes still refers to these as "sectors", even though the cell size changed for 2020.

This pt20so39 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.

pt20sor3 displays individual 3-inch orthophoto tiles areas where each ortho tile covers a square area consisting of a full "cell".

pt20sor9 displays individual 9-inch orthophoto tiles areas where each ortho tile covers a square area consisting of one full "cell".

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 2020 data "AZPIMA20-TILES-3INCH" and "AZPIMA20-TILES-9INCH" directories.
Known errors/qualificationsWhile these Pictometry cells are approximately 1/2 mile square, they are not based on PLSS sections and are offset considerably from the PLSS section grid.
