科学家检视这些地图与数据，与过去风暴(如纳吉斯)的实际观测做比较，来评估模型的准确性。

Scientists study the maps and data from the model and compare them against real observations of a past storm (like Nargis) to evaluate the model's accuracy.

Placebase在原始地图数据顶端的层可以抽取出一个基础的服务，这样用户可能根本不会注意（除非，当然，还有性能，准确性或容量的问题）。

Placebase layers on top of raw map-data would abstract a new underlying service so that users may not even notice it (unless, of course, there are performance, accuracy or capability issues).

在栅格数据模型中，地图的准确性还依赖于地图的比例。

In the raster data model, the map's accuracy also depends on the map's scale.
