vector map

基本解釋

A lossless data hiding algorithm for digital vector maps based on difference expansion is proposed in this paper.
基於差值擴(kuò)大的思想，提出了一種應(yīng)用於矢量地圖的無損數(shù)據(jù)隱藏算法。
To get appropriate electronic vector maps are often expensive and difficult during the development of a small and low cost GIS.
在低成本地理信息系統(tǒng)開發(fā)過程中，郃適的電子矢量化地圖的獲得往往不太容易或費(fèi)用高。
A difference histogram-based reversible data hiding algorithm was proposed for authentication and covert communications of vector maps.
提出一種基於差值直方圖的可逆數(shù)據(jù)隱藏算法，用於矢量地圖的認(rèn)証和隱秘通信。

The other thing these low-bandwidth vector maps enables is offline caching of maps, specifically your most frequently visited locations, and entire trips that have been routed in Navigation, including potential reroutes.
ENGADGET: Google Maps 5.0 hits Android, includes new 3D map view and offline Navigation
We launched Maps initially with the first version of iOS. As time progressed, we wanted to provide our customers with even better Maps including features such as turn-by-turn directions, voice integration, Flyover and vector-based maps.

For example, the vector-based maps load quickly and allow for smooth tilting and rotating of 2D and 3D views.
