Listed national flag on land with no indication that there is a
separate flag for the voyage there.
Therefore, for the proper use of flags has been
developed the following scheme:

The fields mean:

HF = merchant flag, national flag for navigation
DF = service flag, flag for customs, police and other authorities

More extensive books and publications, which also usually well
based on a scientific basis, using this scheme.
There are inserted then only points in the appropriate field.

As the following examples is the use of Scheme, together with
the ratio of height to length next to the image of the flag.
