This is a 3D map of the world. You can rotate it with the two sliders You can also add new places on the map by giving the coordinates for 'Leveys' (=Latitude) and 'Pituus' (=Longitude) and clicking 'Lisää paikka'-button (=Add place). The place will get its name from 'Paikan nimi' (=Place name). If the 'Paikan nimi' is empty the button adds a place without a name. I my self got bored after adding the coastal cities of Africa, Europe and Asia. So you can do the rest... If the map looks too messy you scan try zooming.
