Test09 OBoptimal

Goal

The point of this test was to evaluate how well SPC could create a bigmap of a tag site (1) using optimal imaging data from Orbit B. Optimal imaging data implies images taken of the tag site occur when the spacecraft and sun are at perfect azimuth and zenith angles so, that all parts of the tag site ( e.g. sides of craters & sides of boulders) could be captured out of shadow. RMS measurements from CompareOBJ that compare the SPC model with the truth model were used to judge the created Bigmap, along with traces and a heat map. Furthermore, the bigmap of the tag site was not the only bigmap evaluated. Five smaller bigmaps fore five Lockheed features respectfully were also evaluated.

Imaging Data

To replicate a terminator orbit trajectory (e.g. Orbit B), sun and spacecraft zenith angles during image capture were selected so that their sum equals 90 degrees. Also, many of the sun azimuth angles chosen are impossible, which was ignored during this test due to the assumption that the imaging data is perfect (We played God) for SPC with the only constraint being that the spacecraft has to be in a terminator orbit. A readme.txt file showing the image angle parameters for each image are shown below, along with the polars.

These Sumfiles and and Nominals were created for the first optimal orbit b test.

The optimal otbit b test is done to see what SPC can do with the best orbit b images.

Tagsite 1 Tiling Procedure

A 9cm bigmap of tag site 1 was initialy loaded into the working directory for beginning topography. This was done to replicate a beginning model, similar to what we would achieve in flight from preliminary survey.
