There is a continuous and increasing demand for solutions, both software and hardware-based, that are able to productively handle underground utilities geospatial data. Innovative approaches that are ...
Geospatial locations are increasingly considered as a very important factor for providing diverse kinds of public or proprietary services, such as map services including the real time navigation funct...
The fundamental feature of the next generation LBS systems is supporting the Real-time Traffic Information (RTTI). However, in order to speed up the data accessing, The Physical Storage Format (PSF) o...
Location based services (LBS) is one of the quickest developing technology in the past 20 years. But its QoS (quality of service) is one of critical issues and bottleneck handicapping further developm...
Location Based Services (LBS) provide information and data to the user based on geographical position. These services are usually based on a communications network and one or more positioning technolo...
With the increasing number of geographical data and distributed geospatial applications with heterogeneous databases, many problems may arise while integrating the details of user‘...
The Location Based Service (LBS) market has been growing tremendously over the last few years. Mobility and positioning(especially indoor) have been the key features behind the success of LBS. Bluetoo...
LBS(Location Based Services)动态数据管理面临的一个严峻的挑战是需要在一个有限带宽、移动的、不稳定的环境中为用户提供相对稳定的服务.基于关联规则挖掘的思想,试图从业已形成的海量服务数据中发现潜在的规律,以指导服务器有效地完成数据分发工作.但经典的Apriori算法并不适合时序数据的处理,而现有的时序关联规则挖掘算法又对服务的关联时间阈值考虑不够,故对经典的Aprior...
在简要介绍J2EE开发平台的基础上,分析LBS系统设计的原则和数据设计的要求,讨论基于J2EE开发平台的LBS系统4层网络模型的构成,以及在此平台上开发LBS系统的关键技术.
摘要: 分布式移动地理信息系统是传统GIS在21世纪移动互联网时代发展的新方向,笔者分析了应用于空间定位服务(LBS)的分布式移动地理信息系统(DM-GIS)的原理,特点和有关关键技术,提出了应用DM-GIS技术的解决方案。
