E. Site Metadata
E.1. Digital Photographs
    A set of sharply focused digital photographs, at least 300 dpi at 5”x7”, 
are required to evaluate and document a site. When taking photographs, 
please remember that their purpose is to give a clear view of the equipment 
being used, how it is assembled, as well as the space around it for someone who 
has not visited the site. Photographs must use the filename specified in bold 
between the dashes - (where ssss is the 4-charcter site ID). The convention 
to use for azimuth direction is 000 - north, 090 - east, etc. Jpg format is 
preferred. The photographs must include:

        - ssss_monu.jpg -  A photograph showing the monument (pillar/braced/building) and antenna. 
          The ground surface of the building or monument and antenna must be visible.
        - ssss_mark.jpg - A photograph showing the mark. If no unique mark exists then a photograph of
          the threaded section of the mount, either laterally or from above the monument should be taken. 
          (If the site has been collecting data then DO NOT REMOVE the antenna and instead ignore this photograph.
        - ssss_ant_monu.jpg - A close-up photograph that shows how the antenna is attached to the monument.
        - ssss_ant_sn.jpg - A close-up photograph of the antenna showing its model and serial number.
        - ssss_rec_sn.jpg - A close-up photograph of the receiver showing its model and serial number.
        - ssss_rec.jpg - A photograph of the receiver location.  

        - Four oriented photographs taken at the height of the ARP surface.  The antenna should be included in the 
          photograph but it should not significantly block the ability to view what lies behind the antenna. 
          Stand about 3-5m away. If this is not possible place the camera directly at the top center of the antenna, 
          and point the camera in the required direction:
        - ssss_ant_000.jpg - North   (000)
        - ssss_ant_090.jpg - East    (090)
        - ssss_ant_180.jpg - South   (180)
        - ssss_ant_270.jpg - West    (270)

        If the antenna is on a roof, you must include the following:
        - ssss_ant_bldg.jpg - A photograph showing “clearly” how the antenna is attached to the building.
        - ssss_ant_roof.jpg - A photograph showing the antenna and the roof surface.

These photographs must be updated if the equipment changes or changes occur in the physical space around the antenna.
