What do the numbers on the MIDRs indicate?
Each MIDR has an identification number of the form t-MIDR.xxHyyy;C, where t is the data type: F, C1, C2, or C3; xx is the approximate latitude of the center of the mosaic, H is the hemisphere (N or S); yyy is the approximate longitude of the center of the mosaic; and C gives the cycle and version number. For cycle 1, C is a one digit number giving the version number. For cycles 2 and 3, C is a three digit number, with the first digit being the cycle number and the last the version number. For example, F-MIDR.15S140;301 is a full-resolution mosaicked image data record, centered at 15 degrees south latitude and 140 degrees longitude, from the third data cycle, version 1.
