Each F-MIDR is in a sinusoidal equal area projection and has an origin at 0 degrees latitude, with the central meridian defined as the longitude bisecting the mosaic. Each F-MIDR has 7168 lines (aligned with latitude) by 8192 samples, arranged on the CD-ROM as 56 1024 x 1024 files. F-MIDRs have been generated for key terrains on the planet, regions where highest spatial resolution is required for analysis. The 1024 x 1024 files have a VICAR2 format, with an imbedded VICAR2 label. The data have been placed on CD-ROMs with documentation and detached Planetary Data System labels. Over the course of the first mapping cycle 350 F-MIDRs have been generated, covering more than 15% of Venus, and constituting about 20 Gbytes of data. F-MIDRs also exist as photoproducts that have had a linear contrast enhancement applied. Photoproducts are generated from the 7K x 8K assemblage of files, so there is one photoproduct per F-MIDR. Finally, in some cases a cross track seam removal process has been applied. See the CONTENTS.TAB file on the relevant MIDR CD-ROM volume for information on which MIDRs have been seam-corrected. Please refer to the F-BIDR (MGN-V-RDRS-5-BIDR-FULL-RES-V1.0) data set description for more details on radiometric and geometric processing of Magellan SAR data."
