Detect non-missing values.
Historically, NA values in a GeoSeries could be represented by empty geometric objects, in addition to standard representations such as None and np.nan. This behaviour is changed in version 0.6.0, and now only actual missing values return False. To detect empty geometries, use
- A boolean pandas Series of the same size as the GeoSeries,
- False where a value is NA.
