Claim 27:
28. A device adapted to code point cloud data, the device comprising:
a memory configured to store data representing points of a point, cloud; and
a processing system comprising one or more processors implemented in circuitry, the processing system configured to:
determine height values of points in a point cloud;
code a data structure including data representing a top threshold and a bottom threshold;
code data that represents a midpoint between a top threshold and a bottom threshold:
code data that represents a distance from the midpoint to the top threshold and the bottom threshold;
classify each of the points into either a set of ground points or a set of object points according to the height values, including:
classify points having height values below the threshold into the set of ground points; and
classify points having height values above the threshold into the set of object points; and

code the ground points and the object points according to the classifications.
