![]() "Recenter & Zoom" reprojects and recenters the map and zooms in one level."Recenter" reprojects and recenters the map on the clicked location.Selecting a "Single-click action" will cause one of the following actions to take place when the map is clicked: Edit one or both coordinates and press enter or click the "Recenter & Reproject" button to reproject the map centered on the chosen location. For example, polar stereographic projections have fixed centers (the corresponding pole) so neither field is shown. If either coordinate is not applicable to the selected projection, it is not displayed. Text boxes labeled "Center Latitude" and "Center Longitude" display the center coordinates of the projection. "Object to view" and "Projection" drop-down boxes allow switching among various planetary bodies (may be unavailable, if not configured), and the projection in which the map displays.

Topography for the north and south poles was supplemented with NASA's Lunar Orbiter Laser Altimeter data.įor more details about the map, read the abstract or download it directly at the Unified Geologic Map of the Moon website. "It provides vital information for new scientific studies by connecting the exploration of specific sites on the moon with the rest of the lunar surface."Įlevation data for the moon's equatorial region came from stereo observations collected by the Terrain Camera on the recent SELENE (Selenological and Engineering Explorer) mission led by JAXA, the Japan Aerospace Exploration Agency. "This map is a culmination of a decades-long project," said Corey Fortezzo, USGS geologist and lead author. This resolved issues from previous maps where rock names, descriptions and ages were sometimes inconsistent. Along with merging new and old data, USGS researchers also developed a unified description of the stratigraphy, or rock layers, of the moon. The existing historical maps were redrawn to align them with the modern data sets, thus preserving previous observations and interpretations. To create the new digital map, scientists used information from six Apollo-era regional maps along with updated information from recent satellite missions to the moon. "So, it's wonderful to see USGS create a resource that can help NASA with their planning for future missions." "People have always been fascinated by the moon and when we might return," said current USGS Director and former NASA astronaut Jim Reilly. The digital map is available online now and shows the moon's geology in incredible detail (1:5,000,000 scale). The lunar map, called the "Unified Geologic Map of the Moon," will serve as the definitive blueprint of the moon's surface geology for future human missions and will be invaluable for the international scientific community, educators and the public-at-large. Have you ever wondered what kind of rocks make up those bright and dark splotches on the moon? Well, the USGS has just released a new authoritative map to help explain the 4.5-billion-year-old history of our nearest neighbor in space.įor the first time, the entire lunar surface has been completely mapped and uniformly classified by scientists from the USGS, in collaboration with NASA and the Lunar Planetary Institute. It will serve as a reference for lunar science and future human missions to the Moon. This geologic map is a synthesis of six Apollo-era regional geologic maps, updated based on data from recent satellite missions.
