REJECT IF: · Ground features aren't interpretable in shadow areas. ACCEPT IF: · Most features in shadow areas are interpretable. 5. Contrast Desired contrast levels vary among users, depending on the orthophotography's intended use. Users who overlay vector data on imagery often prefer flat-looking imagery so the vector data are more visible. Also, users who plan to make hard-copy reproductions often prefer low-contrast imagery. However, many users say high-contrast imagery is more aesthetically pleasing to view and interpret. Good communication between the imagery user and Sanborn at the initial stages of a project will help save time and effort in determining contrast criteria. There's a balance between conserving detail in bright and shadowed areas, and producing high contrast. By maintaining this balance, acceptable Orthophotography will be achieved. REJECT IF: · Overall imagery contrast doesn't meet specifications set at beginning of production. ACCEPT IF: · Overall imagery contrast meets specifications set at beginning of production. 6. Foreign Artifacts and Scratches Hairs, lint, dust and scratches can be introduced to Orthophotography during photo capture, film processing and scanning. The aerial camera itself can be the source of film scratches. Also, each time the film is a processed, additional artifact can be introduced. Scanning the original negatives will minimize scratches and artifacts. After scanning, artifacts and scratches can be carefully removed. This operation should be kept to a minimum, however, because ground detail can be removed along with the artifacts. A level of foreign artifacts that don't obscure ground features usually is acceptable. 14 Services Agreement between The Sanborn Map Company, Inc and Cass County, North Dakota
