基于MOGIS的导航地图增量更新

随着社会的发展,GPS导航已经得到了广泛的应用.人们对导航的要求也越来越高,其中导航电子地图的现势性已成为衡量导航优劣的重要标准之一.传统的版本式更新已不能满足需求,增量更新方法应运而生.对增量更新的方法进行·了研究,建立地图要素全局标识体系——MOGIS,并采用SIMG的格网划分方法,利用数据差分技术实现了导航电子地图的增量更新.

Study on Incremental Update Methods of Navigation Electronic Map based MOGIS

With the development of society,GPS navigation has been used widely,the requirements to navigate has increased higher than before.The current trend of electronic navigation has become an important standard to measure the merits of navigation.And the traditional update method of version of style can not meet the needs of navigation,incremental update became to an important way.An incremental update methods are studied for establish a Map object global identification system — MOGIS,and with SIMG method and data difference technology to achieve incremental update of the navigation electronic map.
