While you're busy making a tour, here are a few
hints and tips to help you create an informative and smooth tour:
Try to order your placemarks in such a way as to make the tour
self-playing. They should be in linear order so that the view moves
from one to the next, rather than jumping all over the area.
Use appropriate icons for each placemark. For parks, ue the tree icon
and for churches, use the church icon. This gives your audience an
immediate clue as to what the placemark is.
Fill in a brief summary of the placemark in the description box. You
might know what "the roundhouse" is, but your audience might not.
The description box for each placemark accepts HTML - take advantage of
that.
If possible, include a link to a page with more information.
If your tour has a very large number of placemarks, consider grouping
them in categories with their own sub-folder. Right-click on your tour
folder in the Places pane and select "New...Folder".
Google Earth lets you zoom, pan and tilt the viewpoint - the view for
each placemark should take advantage of that and show the location
as best as possible. If you find a better view for a placemark, right
click it and select Snapshot viewpoint.
