spherely.is_prepared

spherely.is_prepared(geography, /)

Returns True if the geography object is “prepared”, False otherwise.

A prepared geography is a normal geography with added information such as an index on the line segments. This improves the performance of many operations.

Note that it is not necessary to check if a geography is already prepared before preparing it. It is more efficient to call prepare directly because it will skip geographies that are already prepared.

Parameters:

geography (Geography or array_like) – Geography object(s).
