Metadata: ROLL field |
NASA has used the single letter E to identify images that were originally captured in digital form including electronic still camera (ESC) and High Definition Television (HDTV) images. The NASA number is of the form sXXeYYYY where XX is the 2-digit Shuttle Mission, and YYYY is an arbitrarily assigned sequential number. This database organizes photograph identifiers (IDs) into three components, a mission component, a roll component and a frame component. In order to accommodate ESC and HDTV imagery, since it has no film "roll", it was originally decided to use "ESC" and "HDTV" as the roll. This provided more clarity to the casual user and helped avoid possible future conflicts with other non-ESC/HDTV roll IDs being assigned E (some roll IDs in the past have been single letters). EarthKAM (also known
as KidSat), a NASA-funded educational project where middle school students control a camera
mounted on the Space Shuttle or International Space Station, has cross-indexed its images
with our database so that searches of our database will also find relevant EarthKAM images.
During its time on the Space Shuttle, the EarthKAM-assigned number is of the form STS0XX-ESC
-YYYYYYYY, where XX is the 2-digit Shuttle mission number, and YYYYYYYY represents the MET
(mission elapsed time) of the image. These images were also numbered separately by NASA,
and a cross-reference table is available. From
the International Space Station, EarthKAM numbers will be of the form |
