RADARSAT ANTARCTIC MAPPING PROJECT (RAMP)
ANTARTIC MAPPING MISSION-1 (1997)
http://bprc.osu.edu/rsl/radarsat/data
Prior to the mapping mission, the quality of the position and pointing data over the Antarctic
were uncertain. Consequently, ground control points (GCPs) were needed to refine position
knowledge and to act as a validation of the final products. The Environmental Research
Institude of Michigan (ERIM), with the assistance of many organizations which participate in the
Scientific Committee for Antarctic Research (SCAR), put together a database of GCPs which associated
the latitude, longitude, and elevation with points(col, row) on pre-specified RADARSAT-1 imagine chips.

A 25x25km image chip (or subset) was extracted from a pre-specified RADARSAT orbit and frame and sent to ERIM. ERIM used the image chip to locate suitable ground control point(s). The X, Y (row, column) position of that point was tagged with a unique latidute, longitude and elevation.
ERIM supplied back an ERDAS Imagine Map Composer file(s) along with the given image chip. Subsequent GIFs were created at different zoom levels for user convenience.
