摘要：A class of novel spatial relation, internal cardinal direction (ICD) relation, is introduced and discussed. Applying ICD-9 model, the characteristics and the simplification rule of ICD relations are discussed at first. Then the ICD related qualitative spatial reasoning is discussed in a formal way. Four composition cases are presented. They are 1) composing two nesting ICD relations and composing two coordinate ICD relations to deduce 2) conventional (or external) cardinal relations, 3) qualitative distance relations and 4) topological relations respectively. When ICD relations are taken into account, the container determines analysis scale and forms a positioning framework together with ICD relations. So the research on ICD related qualitative spatial reasoning would con-tribute to the representation and reasoning about survey knowledge
