Test 01: First Boulder

Aim and Objectives

Purpose of test: Standard procedure was not creating accurate boulders (see transit below). The boulder was fuzzy, and there was actually a depression where the boulder was located. We wanted to see the effect of tiling over a large boulder (5-10m high) by hand.

Purple is truth, green is model

Additional Objectives

• This was our first attempt at tiling by hand, so we were gaining experience with special cases.

Methodology

Data

• Approach and Detailed Survey images of Shape 3.7.

Results

• We tiled at higher and higher GSD, but we were not able to get to a high enough GSD to properly represent the boulder. The image pixel size was just not high enough to support the small maplets needed to properly represent the boulder.

Conclusions and Recommendations

• If we want to accurately represent these large boulders, we will need better images. This may require additional image planning during the mission if we need to properly represent these large boulders.
