dual grid meaning in English
双栅的
Examples
- Dual grid is another spatial expression approach based on discrete geometry
双网格也是一种基于离散几何的空间对象表示方法。 - Different from realms , dual grid adopts finite precision rational coordinate system , which can express intersection points exactly . therefore , the complexity of spatial redrawing can be avoided , and spatial management subsystem can be implemented easily
与realms不同，双网格使用了有限精度的有理数坐标系统，能够准确表示线段的交点，从而避免了复杂的空间调整，使空间管理子系统易于实现。 - The underlayer spatial database of stadbsii is based on realms and supports dual grid techonology . it can express spatial object discretely and avoid the complexity of spatial redrawing . the underlayer support makes it easier to implement efficient spatio - temporal management and spatio - temporal analysis operations
Stadbsii系统的底层空间数据库以realms为基础，同时采用了双网格技术，在离散表示空间对象的基础上避免了复杂的空间调整，为实现高效的时空存取以及时空分析操作提供了底层保证。
