Report of the Annual Meeting of Planetary Geologic Mappers NASA Goddard Space Flight Center Greenbelt, Maryland June 21 to 24, 2011 The construction of cartographic products to illustrate the surface characteristics of planetary bodies beyond our own has historically been met with particular challenges. These challenges can be overcome through innovative adaptation to burgeoning data sets and analytical technologies as well as a focused forum within which to present, critique, and discuss both technical approaches and scientific results. To assist, the Annual Meeting of Planetary Geologic Mappers (PGM) provides a unique forum for planetary scientists to address these challenges through the exchange of ideas and experiences relating to the creation, publication, and promotion of planetary geologic maps. PGM 2011 was convened by NASA’s Planetary Geology and Geophysics (PGG) program Geologic Mapping Subcommittee (GEMS) Chair Les Bleamaster (Planetary Science Institute (PSI) and Trinity University), USGS Geologic Map Coordinator Ken Tanaka (U.S. Geological Survey (USGS) Astrogeology Science Center), and PGG Program Scientist Mike Kelley (NASA Headquarters) on June 21 to 24, 2011. Scott Mest (PSI and NASA Goddard Space Flight Center (GSFC)) hosted the meeting at GSFC in Greenbelt, Maryland. This volume contains summaries of PGM 2011 events and discussions, a schedule of presentations, submitted abstracts (attending and in absentia), and the 2011 Planetary Geologic Mappers’ Handbook (including updates since prior annual versions). The meeting began with a one-day Geographic Information System (GIS) “round- table” presentation, discussion, and question-answer session on Tuesday, June 21, which was attended by 12 people. The informal event was led by Trent Hare, Corey Fortezzo, and Jim Skinner (all of USGS) and focused primarily on digital data set acquisition and display, vector editing, and updates/changes in recent GIS program releases. As in past years, the goal of the GIS round-table was to help promote digital mapping, review, and publication standards, as recommended by USGS and required by PGG. Science, programmatic, and technical presentations were held on Wednesday, June 22 and Thursday, June 23. Presentations began with welcoming comments by Les Bleamaster, logistical points by Scott Mest, an update on the status of mapping projects and publications by Ken Tanaka, and a summary of the current state of the PGG program generally and PGG-funded map projects specifically by Mike Kelley. Programmatic presentations were followed by a technical presentation by Trent Hare, who reminded the community of the resources available to planetary mappers, including the USGS Photogrammetry Lab, the (newly-funded) Mapping, Remote Sensing, Cartography, Technology, and Research (MRCTR) GIS Lab, and an upcoming submission and tracking website to assist with the review and publication of NASA-funded geologic maps. Twenty six abstracts were submitted this year (15 Mars, 5 Venus, 3 Lunar, 1 Io, 1 Mercury, and 1 technical). From these, 19 were scheduled for presentation, focusing on ongoing, variously scaled map-based science investigations. Detailed discussions of particular projects were promoted by accompanying hard-copy maps and posters, which were viewed along the walls of the presentation hall during scheduled break-out sessions. Presentations on Wednesday, June 22 focused on Io, the Moon, Mercury, and Venus, each at a variety of map scales. A reception and group dinner was organized by Scott Mest at the NASA GSFC recreation center on Wednesday evening. Presentations on Thursday, June 23 focused exclusively on Mars and ranged from global (1:20,000,000) to local (1:24,000) map scales using a variety of data sets. Science presentations on Thursday were followed by a discussion on various aspects of the current state of the mapping program. Les Bleamaster announced that he will be stepping down as GEMS chair and that, after a few months of programmatic transition, Jim Skinner will take over responsibilities in late 2011. Discussions also included general and specific approaches to reinforce the publication, promotion, and use of geologic maps as contextual scientific products within the planetary science community. Of particular relevance was a discussion regarding the means by which funds are allotted for USGS review and publication, particularly in light that several NASA programs (other than PGG) allow for the production of PGG-funded geologic maps. There was broad consensus that the mapping community requires clarity on how the health of the planetary geologic mapping program can not only be sustained but improved. The meeting ended with a guided tour of NASA GSFC spacecraft testing facilities on Friday, June 24.
