Image Log / Image Log Float 2 / Image Log Float 4
Description:
In general the Image Log handles an array of data where one dimension consists of
equally sampled depth and the second dimension of radial equally sampled data
values (one data point every x degree of an arc). The Image Log stores and displays
acoustic scanner data (e.g. amplitude, travel time, thickness) as well as multi arm
caliper or FMI data. Three different types of Image Logs exists each of them storing
the data using a different data type.
The Image Log Integer stores all values as unsigned integer (two bytes), which
means that all values are between 0 and 65535. This is sufficient for acoustic scanner
travel time and amplitude measurements or other data where no negative or decimal
numbers occur. Image Log Float 2 (two bytes) and Image Log Float 4 (four bytes)
types store data as floating point values, which allows proper handling of negative
and decimal numbers.
Data Format:
E.g.
Depth, Amp1, Amp2, Amp3, … , AmpN
