1 Each Isis Cube file is distributed as a compressed archive in GZIP format. The GZIP archive can be uncompressed with utilities such as gunzip (Unix/Linux), WinZip (Microsoft Windows), or Aladdin Systems' Stuffit (Mac).

2 The file naming convention is:

M[resolution][latitude][longitude][options].[data format].[file format]

where

  • M: MDIM
  • resolution:
    • E = 16 pixels/degree
    • G = 64 pixels/degree
    • I = 256 pixels/degree
  • latitude/longitude: the coordinates of the center of the quad
  • options: optional information, such as 8bt = 8-bit data
  • data format: for gzipped files, indicates the format of the archived data. CUB = Isis Cube Format, IMG = PDS Format
  • file format: the format of the download file. JPG = JPEG (Joint Photographic Expert Group) image format, GZ = Gnu ZIP compressed archive format.

3 When displaying large JPEGs, some browsers may not display them well or at all, or may return an error message. If you are experiencing an issue diplaying a large JPEG, try downloading the file to your computer:
  • Mac: Move the mouse cursor over the link to the image and hold down the mouse button to make a menu appear. Select the option "Save target as..." (may also be labeled "Save link as..." or "Save link target as...").
  • Windows, Unix, and Linux: Right-click the link to the image and select the option "Save target as..." (may also be labeled "Save link as..." or "Save link target as...").

4 Some applications may not be able to open very large JPEG images, and may return an "illegal image width" error message, or "parse error" message. If you are experiencing an issue working a large JPEG, try viewing the image using a different application, such as:
  • IrfanView: Freeware image processing application for Windows.
  • Paint Shop Pro: Shareware image processing application for Windows.
  • The Gimp: Freeware image processing application for Linux, Windows, and Mac.
  • JView: Freeware image viewer for Mac.
An image processing application can be used to break large images into smaller subareas (using a crop tool), or exporting to an alternative format. See the Planetary GIS Discussion Board for additional information. Contact the web developer with additional questions or concerns.
