PDS_VERSION_ID = PDS3 RECORD_TYPE = STREAM OBJECT = TEXT PUBLICATION_DATE = 2006-04-01 NOTE = "Description of the data directory contents for this Cassini ISS Cartographic Map Volume." END_OBJECT = TEXT END DATA Directory Contents This data directory contains the cartographic map sheets, the processed tile images used to create the cartographic map sheets, and a simple cyclindrical global mosaic image. The full cartographic mapping product for a particular target body is composed of one or more cartographic map sheets. These map sheets are stored in PDF format and are located in the /maps/ subdirectory here. A map sheet will contain one or more images of different projections of the body. These images are stored in PDS VICAR image format and are located in the /images/ subdirectory. The full simple cyclindrical global mosaic image is also stored here. (see aareadme.txt for information on file formats) The filenaming convention for the cartographic map sheets reveals their contents and is defined as follows: [satellite abbr]_[scale]_[center lat]_[center lon]_SMN.PDF where: [satellite abbr] = 2-letter abbreviation for the target body [scale] = image scale given in thousands (K) or millions (M) of meters [center lat] = latitude at the center point of the image [center lon] = longitude at the center point of the image examples: SE_500K_44N_225W_SMN.PDF (Saturn/Enceladus map sheet centered at 44 degrees North latitude and 225 degrees West longitude, taken at 500 kilometers resolution) SP_1M_0_0_SMN.PDF (Saturn/Phoebe map sheet centered at the equator and 0 degrees West longitude taken at 1 million meters resolution) The filenaming convention for the tile images reveals their contents and is defined as follows: [satellite abbr]_[scale]_[center lat]_[center lon]_[type].IMG where: [satellite abbr] = 2-letter abbreviation for the target body [scale] = image scale given in thousands (K) or millions (M) of meters [center lat] = latitude at the center point of the image [center lon] = longitude at the center point of the image [type] = projection type (MERCATOR, LAMBERT, STEREO, or SIMP) examples: SE_500K_43N_135W_LAMBERT.IMG (Saturn/Enceladus tile using Lambert projection centered at 43 degrees North latitude and 135 degrees West longitude, taken at 500 kilometers resolution) SP_1M_90N_0_STEREO.IMG (Saturn/Phoebe tile using Stereo-graphic projection centered at the north pole taken at 1 million meters resolution)
