[PPS08-P05] Positive openness map for visual inspection of fault scarp associated with lunar wrinkle ridges
Keywords:moon, wrinkle ridge, positive openness map
We applied the positive openness as a representative parameter of solid of the sky extent over a point of interest as a parameter for preparing effective data to identify candidates of fault scarps associated with wrinkle ridges. Positive openness map could be calculated from lunar Digital Terrain Model (DTM) acquired by Terrain Camera/Kaguya. Radial limit which is the range of positive openness calculation for the interest, affects the difference in vision of enhancement of topographic features. As a result of several radial limits calculations, we adopted radial limit of 222 m as a most appropriate one. By using of positive openness map, we could found several candidates of fault scarps associated with wrinkle ridges.
