To the question of buffer generation for linear objects in GIS, nowadays most of existing studies devote to the algorithms of buffer generation in which the factor of director is not considered because of its complexity, and few people pay attention to study on the lateral buffer generation. This paper attempts to explore and give some preliminary solutions about the lateral buffer generation for linear objects. First it discusses the definition of left and right sides about linear objects, and a new method to determine the lateral relation is designed based on this definition. Furthermore, it puts forward two methods of lateral buffer generation, and gives the implementation steps in detail. In addition, the paper takes some vivid examples to analyze the characteristic and potential problems of these two methods, which have some referenced value to the kindred researches in algorithm design of lateral buffer generation.
