"We catch a glimpse of a huge swirl of clouds out the window over the middle of the Pacific Ocean, or the boot of Italy jutting down into the Mediterranean, or the brilliant blue coral reefs of the Caribbean strutting their beauty before the stars. And...we experienced those uniquely human qualities: awe, curiosity, wonder, joy, amazement." (Russell L. Schweickart, Apollo Astronaut ("The Home Planet")
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.
