RADARSAT-1 Antarctic Mapping Project (RAMP) Data

Mini Mosaics are 10m, 16-bit binary mosaics of select areas of
fast moving glaciers in Antarctic (see map.jpg).  A manual geographic
correction was applied to the mosaics to correct for small offsets
in gelocation (see DOCS/mini_mos_offset.pdf)

 1.  Introduction

 During September-November 2000, The RADARSAT Antarctic Mapping Project (RAMP) acquired SAR data
 over Antarctica. Coverage extended from 80-degree S latitude to the coast.
 The data have been orthorectified and compiled into 25 m mosaics.  Fast glacier flow regimes
 have been selected for special processing using Fine-1 beam data.  Compiled as mini-mosaics,
 these products consist of 10m 1-look data.  There are 33 minimosaics and the data and
 metadata are presented here. 

 2.  Beta product

 This is a beta product, the final product is awaiting geolocation refinement.  This
 refinement of the final grand block adjustment consists of a least squares adjustment
 amongst all the individual blocks.  The geolocation information associated with the beta
 mini-mosaics is based on a block adjustment unique to each block.  The difference between
 the final and beta version geometry is expected to be about 50 m.

 3.  Basic Explanation of files and their format
     Binary files are in Polar Stereographic projection, WGS_84

 There are 4 kinds of files in the directory:

 1. bin files - These are generic binaries, 2 in each sub-directory for 10m and 250m data.
 2. hdr files - These are the header files containing the metadata for the generic binaries.
 3. map file - This file has the map coordinates and projection information for the 10m data.
 4. jpg file - Quicklook image file.
 For example:
 mm_01.jpg - Quicklook image file
 mm_01_10.bin - 10m, 16-bit, generic binary data.
 mm_01_10.hdr - header file for the 10m 16bit binary.
 mm_01_10.map - Map projection and corner coordinates for the 10m binary data file.
 mm_01_250.bin - 250m, 8-bit, generic binary data.
 mm_01_250.hdr - header file for the 250m 8bit binary data.


 4. Map reference

 The image file called 'map.jpg' in this directory shows the spatial information for each
 image data.

 6.  Directory Structure

 The center latitude/longitude information for each minimosaic is shown in the look
 -up table below:
