LBS服务包含两大要素,位置(经纬度)和地理描述,分别对应两大技术领域,即定位技术和地理信息技术。随着终端技术的不断进步和互联网技术的发展,位置服务从原来的专业领域逐渐走向民用,得到了广泛的普及。就定位技术而言,目前除了传统的GPS定位技术之外,还有网络定位技术、辅助GPS技术、混合定位技术等,定位手段的丰富使定位不再依赖专用终端,使用普通
LBS service contains two major elements, location (latitude and longitude) and geographical description, corresponding to the two major technical areas, namely positioning technology and geographic information technology. With the continuous improvement of terminal technology and the development of Internet technology, location service has been gradually popularized from the original professional field to civilian use. In terms of positioning technology, in addition to the traditional GPS positioning technology, there are network positioning technology, assisted GPS technology, hybrid positioning technology, the rich positioning means that the positioning is no longer dependent on the dedicated terminal, use the ordinary
