            if relevant.

        9.  **Titling:** If film is used, each exposure shall be clearly
            titled along the north edge (if flown north-south) or west
            edge (if flown east-west) of the photography. Each exposure
            shall be marked clearly with a numerical abbreviation of the
            month, day and year of exposure, the number of the roll, the
            number of the exposure on the roll, the photo scale
            expressed as a ratio, and the three letter designator
            **BOS07**. The rolls of film used on the Boston MA project
            shall be numbered consecutively, beginning with number 1;
            and the exposures on each roll shall be numbered
            consecutively, beginning with the number 1. Coarse Airborne

        GeoTIFF files shall represent "tiles" 1500 meters X 1500 meters
        cut at even 1500 meter grid lines with no overedge. Corner
        coordinates will be based on the UTM Grid and shall be evenly
        divisible by 1500 meters. Tiles shall be accompanied by an index
        sheet and shape file suitable for loading into ArcGIS. Index
        sheet shall include tile boundary and filename. The Index sheet
        collar shall include Latitude/Longitude reference coordinates.

    2.  **Digital orthophoto characteristics:** Relative join
        (misalignment) of transportation features between adjacent image
        chips/tiles shall not exceed 1-meter. Orthophotos shall be
        tonally balanced to produce a uniform contrast and tone across
        the image tiles of the entire project. Changes in color balance
        across the project, if they exist, shall be gradual. Abrupt
        tonal variations between tiles are not acceptable. Building tilt
        shall be corrected to the extent that transportation features
        are not obscured. Ground features appearing in the orthophoto
        imagery, such as building roof tops, water towers, and radio
        towers, shall not be clipped at seamlines or between individual
        tiles. Image artifacts introduced during the scanning process
        and appearing in the final orthophotos are unacceptable, except
        for very minimal artifacts falling in non-critical coverage
        areas, e.g., a small piece of lint appearing in a timbered area.

        shall be derived from the southwest corner of each tile and
        shall be based on the U.S. National Grid. File names will
        include Grid Zone Designation (GZD), 100,000 meter block
        designator and X and Y grid coordinates truncated to 100 meters.
        Supplemental instructions for naming Digital Orthorectified
        Image tiles are included in Attachment B, U.S. National Grid, of
        this task order.

    5.  **Elevation data:** The elevation data created for use in the
