MGN V RADAR SYSTEM DERIVED MIDR COMPRESSED ONCE V1.0
Listed in NASA Data Portal
This data set contains the Magellan Compressed Once Mosaic Image Data Records (C1-MIDRs) which consists of mosaics generated from compressed basic image data records (C-BIDRs).
Description
C-BIDRs have been generated by computing 3x3 pixel arithmetic moving averages from the F-BIDRs. Each C1-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 C1-MIDR has 7K lines (aligned with latitudes) and 8K samples, arranged as 56 1K x 1K files on the CD-ROMs. C1-MIDRs, with their 225m pixel widths, are designed to cover the planet at reasonably high resolution and high signal to noise ratio.
