随着无线通信技术的发展和智能移动终端的广泛普及,基于位置的服务已经融入了人们生活的方方面面.其中,Top-k空间偏好查询在地理信息系统、城市建设规划、资源调度与分配、旅游规划等领域具有重要的意义.Top-k空间偏好查询是根据空间对象周围的特征对空间对象进行等级评价,并返回具有最高等级评价的k个空间对象.目前,对于Top-k空间偏好查询的研究主要集中在欧式空间和路网环境,本文对欧式空间和路网环境下的Top-k空间偏好查询方法进行分析和比较.
Research on Top-k Spatial Preference Query Method
With the development of wireless communication technology and the widespread popularity of intelligent mobile terminals, lo-cation-based services have integrated into all aspects of people's lives.Among them, Top-k spatial preference query has important sig-nificance in fields such as geographic information systems, urban construction planning, resource allocation and tourism planning.Top-k spatial preference query evaluates spatial objects based on their surrounding features and returns k spatial objects with the highest level of evaluation.At present, research on Top-k spatial preference queries mainly focuses on Euclidean space and road network environments. This article analyzes and compares Top-k spatial preference query methods in Euclidean space and road network environments.
