Image Log displayed in Color Image (left), Shifted Curve (mid) and Stacked Curve (right) style.
Description:
The RGB Log is used to display bitmap data such as optical televiewer images, core
photographs, video snapshots etc.. Data is stored in a two dimensional array of RGB
(Red, Green, Blue) intensity triplets. One dimension consists of depth, sampled at a
constant rate, and the second dimension of radial equally sampled data values (one
data point every x degree of an arc). Thus, for each depth increment there is a data
set associated, which represents the full (or partial) coverage of a borehole wall or
core circumference.
Data Format:
Depth, RGB 1, RGB 2, RGB 3, … , RGB N
