Search Camera File Nadir

This tool is for searching the nadir data from uncataloged digital camera images. Digital cameras generate a camera file for each picture they take. We take these camera files and generate nadir data from them, which includes sub-orbital coordinates of the spacecraft at the time the photograph was taken as well as some information about the sun's location. After the photographs are cataloged, this nadir information is added, along with the cataloged information, to the main table of the database. On a daily basis, code is run to search the database table where this pre-cataloged nadir information is stored and clean it of records that have been cataloged.

The accuracy of the nadir information is largely dependent on the accuracy of the time setting of the camera since that time is used to determine the spacecraft's position.
