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 221 map
sheets, including 18 new ones added in 2011, 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, and 25143
Satellites - M1 Phobos, M2 Deimos, J5 Amalthea, S7 Hyperion, and S11
Comets - 81P/Wild 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.
The map sheets are provided as jpeg files in the document directory of the
data set, supported by an html browse page (aamapdesc.html) and a document
describing the map projections used (projections.asc). In the data
directory is an index listing the parameters describing each map
(mapindex.tab). The information in the browse page, the projection
description, and the index were provided to PDS by Phil Stooke.
This data set supersedes the PDS data set EAR-A-3-RDR-STOOKEMAPS-V1.0 which
was reviewed and archived in 2003. The new data set 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.
