[email protected] The Galileo Spacecraft began mapping the Jovian orthographic projection centered at the latitude and system in June 1996. Twelve orbits of Jupiter and more longitude coordinates of the sub-spacecraft point to than 1000 images later, the Solid State Imager (SSI) is still preserve their perspective. Depending on the photometric collecting images, most far superior in resolution to geometry and scale, it may be necessary to apply a anything collected by the Voyager spacecraft. The data photometric normalization to the images. Next, the collected includes: low to medium resolution color data, individual frames are mosaicked together, and mosaicked medium resolution data to fill gaps in Voyager coverage, and onto a portion of the base map for regional context. Once very high-resolution data over selected areas. We have the mosaic is finished, it is checked to make sure that the tie been systematically processing the SSI images of the and match points were correct, and that the frames mesh. Galilean satellites to produce high-resolution mosaics and to We produce 3 final products: (i) an SSI-only mosaic, (ii) SSI place them into the regional context provided by medium- images mosaicked onto regional context, and (iii) the resolution mosaics from Voyager and/or Galileo. addition of a latitude-longitude grid to the context mosaic. Production of medium-resolution global mosaics is The purpose of this poster is to show the mosa- described in a companion abstract [1].
