Hi Dima.
I am also interested in entering placemarks via the component k2.
It's the best idea. From this You should start - You shoud make special plugin ZH G.M. for K2
!!!SUGESTIONS (sorry for my english it is bad):
Polish: Możesz do tego użyć zdefiniowanych pól w K2 - The K2 Extra Fields.
Do integracji użyj właściwie zdefiniowanych pól w K2 - the K2ExtraFields, których nazwy będą miały specjalnie oznaczenia czytelne dla twojego pluginu ZhGoogleMapsForK2. Możesz użyć klamer w nazwie pola Przykład extra field name: {zh google maps placemark info}
GoogleTranslation from Polish: You can do this, use the fields defined in K2 - The K2 Extra Fields.
For integration using well-defined fields in the K2 - the K2ExtraFields whose names will be clearly identified specifically for your plugin ZhGoogleMapsForK2. You can use brackets in the name field Extra field name Example: {zh google maps Placemark info}
I send You a letter and described this via e-mail

After this You shoud read my sugestions described here:
forum.zhuk.cc/index.php/forum/main-sugge...-user-front-formular and add this fields in Your own
made in the future the special integration plugin named ZHGoogleMapsForK2
