• SUMFILES

Example of a SUMFILE

Description

A sumfile is created by the executable make_sumfiles and contains camera data, target-relative position vectors, pointing vectors, uncertainty values, and landmark info for its respected image. Therefore, there is only one sumfile for one image. Sumfiles contain data that SPC uses throughout various executables, like lithos. As SPC is used to correlate images with lithos the sumfile vectors and landmark lists can be updated with the "v 4" command (see lithos section).

Thus, sumfiles can change throughout SPC usage, unlike nominals.

Furthermore, the sumfiles crated by make_sumfiles are named as <image name>.SUM and placed in a directory titled "SUMFILES" within the users working directory.
