The logical coordinates are the offsets as they would be if the pixels themselves were scaled.

逻辑座标则是像素本身缩放时，跟著缩放的位移。

With your selected pixel coordinates and a single-layer base reflectivity map, the logical process for detecting precipitation near a spot on the map is straightforward.

使用选定的像素坐标和单层基本反射率图，检测地图中某个场所附近的降水的逻辑过程将十分简单。

Google does, however, offer its own service to map between logical names and coordinates, which is known as geocoding.

但是，Google确实提供了逻辑名称与坐标之间的映射服务，这称为地理编码。
