| Descriptive name | Pictometry 2018 1 meter Orthophoto Tiles | |
| File name | pt18sor1 | |
| Spatial domain | Eastern Pima County | |
| Abstract | Pictometry uses a grid of squares called "sectors" that define a project area. pt18sor1 is that sector grid for the 2018 Pictometry 1 meter orthophotos in the Tucson metropolitan area. However, while Pictometry delivered this 1 meter sector grid, they did not deliver the corresponding tiled 1-meter orthophoto images. Higher resolution 9-inch and 3-inch orthophoto images are in the Pictometry 2018 data. See layers pt19sor9 and pt18sor3. | |
| Known errors/qualifications | While these pictometry sectors are approximately 1 mile square, they are not based on PLSS sections and are offset considerably from the PLSS section grid. | |
