Data Set Overview ================= This data set collects the maps of small solar system bodies prepared by Phil Stooke of the University of Western Ontario. A total of 270 map sheets are included, some based on photomosaics from spacecraft images and some based on shaded relief maps prepared from spacecraft images. The targets included are Asteroids - 243 Ida, 253 Mathilde, 433 Eros, 951 Gaspra, 2867 Steins, and 25143 Itokawa. Satellites - M1 Phobos, M2 Deimos, J5 Amalthea, S7 Hyperion, and S11 Epimetheus. Comets - 81P/Wild 2, 19P/Borrelly 1, and 103P/Hartley 2. For these maps, the prime meridian is defined according to the existing literature for each body. For all synchronously rotating satellites (Phobos, Deimos, Amalthea, etc.) the prime meridian faces the primary planet. For Gaspra, Ida, and any other objects not in synchronous rotation, the prime meridian is that used in the basic descriptive papers by Peter Thomas and colleagues for each body, and given in the IAU Working Group on Rotational Elements and Cartographic Coordinates triennial reports. Longitudes in every case increase in the direction opposite to rotation. Starting with this version of the map collection (V3.0), the maps of comets and asteroids have been relabelled where necessary for compliance with the IAU guidelines on coordinate systems. In 2003, the IAU Working Group on Cartographic Coordinates and Rotational Elements produced a revised guideline for the coordinate systems of comets and asteroids, having the effect of reversing the longitudes for comets and asteroids with a positive pole north of the ecliptic (Seidelmann et al. 2005). The resulting change affects some of the descriptions and labels of maps for Ida, Gaspra, Mathilde, Eros, Wild 2, and Borrelly. The maps of asteroid Itokawa and comets Hartley 2 and Steins postdate the change in IAU guidelines and are not affected. Planetary satellite maps are not affected. Data ==== The map sheets are provided as jpeg files in the document directory of the data set, supported by an html map guide with full descriptions of the maps (00_map_guide.html) and a document describing the map projections used (projections.asc). Use the html map guide in a browser for easy access to the maps and their associated information. In the data directory is an index summarizing the parameters describing each map ( The information in the map guide, the projection description, and the index were provided to PDS by Phil Stooke. Archiving History ================= This data set supersedes the PDS data set EAR-A-3-RDR-STOOKEMAPS-V1.0 which was reviewed and archived in 2003. The 2011 version of the data set (MULTI-SA-MULTI-6-STOOKEMAPS-V1.0) has the same content as the earlier data set with the addition of 18 new map sheets, and including new target bodies 25143 Itokawa and Comet 81P/Wild 2, and new maps for 433 Eros, Phobos, and Deimos. The 2012 version (V2.0) adds five map sheets, one on Itokawa and four on Comet 81P/Wild 2. The 2015 version (V3.0) adds 44 new map sheets, including new target bodies 19P/Borrelly, 103P/Hartley, and 2867 Steins, as well as new maps on 433 Eros, 243 Ida, and 25143 Itokawa. The 2012 version introduced FITS versions of the map sheets, but these received little to no use, so for the version of 2015 the FITS versions were removed.
