- Abstract
Introduction: MESSENGER data are being used to create quadrangle geologic maps of Mercury [1] in preparation for BepiColombo [2,3]. We present our recently published geologic map of the Hokusai quadrangle (H05; 0–90°E, 22.5–65°N) [4]. Data and methods: Main basemap: H05’s ~166 m/pixel v0 BDR tiles with moderate (~68°) solar incidence angles. Auxiliary basemaps: low (<30°) and high (>72°) incidence angle basemaps; ~665 m/pixel enhanced color mosaic; MLA- and stereo-derived DEMs [5,6]. Map projection: Lambert Conformal Conic (c. meridian, 45°E; st. parallels, 30°N and 58°N; radius, 2,440 km). Scale: Publication scale 1:3M to match other MESSENGER-era quadrangle maps [1]. Digitization scale ~1:400k. Updates: Since publication, we have reconciled the H02–H05 boundary and added an indicative cross-section to the mapsheet. We plan to use “spatial adjustment” to make our shapefiles align with the final topographically controlled H05 basemap tiles.
