Descriptive name		Pictometry Sector Grid
File name		ptnsects
Spatial domain		Pima County
Abstract		ptnsects shows the complete rectangular Pictometry sector grid for Pima County and a few miles beyond. ptnsects shows the entire possible grid and does not represent the area covered by any particular Pictometry project. While Pictometry sectors are approximately 1 square mile, they are not PLSS sections and are not coincident with PLSS section boundaries. This grid was used for Pictometry projects up to 2018. It was replaced with a new grid, pt_grid, for 2020 and beyond.
