【Abstract】 The international standard ISO 19108,2002 "Geographic information-Temporal schema" developed by the International Organization for Standardization will be adopted identically as our national standard GB/T 22022 in the near future.The standard describes temporal relative positions using precise English words and mathematic logic expressions,however,it seems not intuitionistic to understand and it is hard to correspond these English words and logic expressions to Chinese words.To propagandize and carry out the standard,methods for translating temporal relative positions into Chinese and how to display these temporal relative positions by drawing are discussed in this paper,and then all of graphics to display these temporal relative positions contained in the standard are put forward.These graphics turn out to be simple and intuitionistic to understand.更多还原
