网络电子地图的应用及其实现

提高电子地图的速度是所有同类产品要解决的共同问题。通过对电子地图本身进行分析，认为海量的数据处理和网络带宽的限制是影响其速度的主要因素，这两个因素造成的主要影响是数据检索和计算速度慢，地图显示速度慢以及网络传输时延长。提出了相应的解决办法和整套系统的实现构架，整个系统取得了令人满意的响应时间。

Application and implementation of network electronic map

Improving the speed of electronic map is the common problem to be solved all familiar products. By analyzing electronic map, processing mass data and limitation of network bandwidth are main factors of limiting the speed of electronic map and these two factors result in low speed of searching and calculating, low speed of displaying map and long delay of network transmission. According to these problems, corresponding resolvents and implementation architecture of the system are put up. The system gets satisfied response time.
