Io Shaded Relief and Surface Markings of the Ruwa Patera Region
CARTOGRAPHIC CONTROL
Mercator and polar stereographic projections used for the maps of Io are based on a sphere with a radius of 1816 km and a common scale of 1: 4,268,000 at lats ±45˚. Longitudes increase to the west in accordance with the astronomical convention. Planimetric control was derived by photogrammetric triangulation using Voyager 1 and 2 pictures (Davies and Kayayama, 1981). The meridians are numbered according to the ephemeris position of the prime meridian of Io (Davies and Kayayama, 1981; IAU, 1980a).

General
- Purpose
This sheet is one in a series of maps that covers the surface of Galilean satellites of Jupiter at a nominal scale of 1 : 5, 000, 000 (Batson and others, 1980). The source for the series was Voyager 1 and 2 images. Essential features of the mapping are noted below.

Data Status and Quality
- Process Description
A series of mosaics of Voyager 1 and 2 pictures was assembled at 1: 5, 000, 000 using projections described above. Size, shapes and positions of features were taken from the base mosaic using portrayal and interpretation techniques described by Inge (1972) and Inge and Bridges (196). Surface relief is shown as if illuminated from the west. Albedo markings are shown as they appear int eh Voyager pictures. Extreme variations in the picture resolution precluded consistent interpretation and portrayal of the pictures used for map compilations. Further limitations were imposed by dark albedo markings, which tend to obscure distinctive surface details. The colors chosen for his map are intended to provide optimum discrimination of detail and do not necessarily represent the color of Io. Image analysis and airbrush representation were made by Patricia M Bridges.
