Descriptive namePictometry 2018 3 inch Orthophoto Tiles
File namept18sor3
Spatial domainEastern Pima County
AbstractPictometry uses a grid of approximately one-mile square areas called "sectors" that define a project area.

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

The tiles defined by this layer represent the areas covered by each of the 3-inch resolution orthophotos in JPG format in the Pictometry 2018 data "AZPIMA18-TILES-3INCH" directory.

This pt18sor3 layer has been appended with pt18sor9 to make pt18sor39.
Known errors/qualificationsWhile these pictometry sectors are approximately 1/3 mile square, they are not based on PLSS sections and are offset considerably from the PLSS section grid.
