This study involves a quantitative analysis of two maps of the Antarctic continent, one of known bedrock topography, compiled by Drewery and others (1982), and the other comprising NASA Scatterometer data. The objective of this study is to determine if topographic features, indicated on the known bedrock topography map, correspond with those on the map of NASA Scatterometer data. The approach is to draw lineaments on both maps and take strike measurements from a reference point. The orientations of these measurements are compared. A statistical analysis is conducted using rose diagrams, and major measurement trends are taken from these diagrams to be compared between maps. The results include a detailed comparison and discussion of lineaments found on both maps. In general, there is a favorable comparison between both maps suggesting that tonal patterns on the scatterometer data are related to bottom topography. A discussion of lineament trends that correspond to structural features is also included in the results.
