Detailed Description

Cartesian coordinates of points defining a contour.

Format:

Repetitive Data Item, starting with a one-octet Field Repetition Indicator (REP) followed by X and Y coordinates of each point

Structure:

• Bits 24-17 (REP): Number of consecutive points
• Bits 16-9: X coordinate
• Bits 8-1: Y coordinate

Resolution:

• X, Y LSB: 2^(-6+f) NM

Note

f is a parameter of the SOP message

Negative values are in 2's complement form
