The instructions Google provide for the tour functionality in GEarth 5.0 are OK if you want to create a tour around a geographical feature in GEarth such as Mt Everest but often you want to annotate your tour or turn placemarks on or off e.g. to show photos such as this one:
In this tutorial I'll talk you how to best create an annotated tour like this one. Don't be put off by the tutorial length, I've just been detailed in places so as not to confuse people, its not really that complex:
- Create a folder (in places column click a folder such as 'Temporary Places', click 'Add' in the menu bar and select folder).
- Create placemarks, polygons or other elements to be included in the tour (see buttons on the top of the main screen). I've created a tour of Cleobury Mortimer in the UK with placemarks with photos in them and a polygon showing the rough extent of the town.
- Check the elements are in your new folder (if you click the minus in a square to the left of your folder they should shrink up into the folder). If they aren't, simply drag and drop them into the folder.
- Turn all the elements you have created off by unticking the tick box to their left
- Click your folder so it has a blue background then click the 'Record a tour' button in the main button bar above the main screen. It's a video cam icon.
- Click the red 'record' button in the box that appears bottom left
- Move to a position where you can see an interesting view associated with your first placemark (or other element) you created to be in the tour .
- Turn the placemark or element on. If its a placemark you may want to click it in the places column to view the pop up balloon too. You may want to turn it off again before moving to the next step but you can choose what you do and the tour will still work.
- Repeat steps 7 and 8 for all the elements in your tour.
- Click the record button again to stop the tour. It should play what you've just recorded. If you're happy with it, click the disk icon in the tour control box bottom left. If not close the tour control box and return to step 5.
- The tour should appear in your new folder. Turn off (i.e. untick) all the elements in your folder except the tour. Then right click your folder > Save Place as, then save the folder as a file to somewhere sensible.
- Creating the folder is necessary to ensure all the elements in the tour are sent with the tour. My making you turn each element on ensures that the element control works properly and also can be useful when you have lots of data to show - you build the complex map up part by simple part.
- Step 11 is needed so that when the user open's your file then only the tour is clicked. The replay will get mangled if you don't have the tour in this state.
- If you want to use elements from the GEarth layers column then you must copy them into your created folder. Many placemarks in the Layers column can be simply copied (right click > copy) to your new folder. This does not mean that it is legal to do this, I'm not a lawyer so I can't advise on the legaility of doing this.
- You can also record historical data and other clever things in tours but I thought I'd stick to simple things to start with. A simple and very useful next step is to click the microphone button instead of the simple record button and record audio narration of your tour.
- Those who are happy to edit kml files can manually edit tours. John Bailey will probably produce a guest post here in the future about such advanced tour production.
- If you have multiple files open with multiple tours you could have problems playing tours. If things aren't working as they should, make sure you close the tour box (bottom left) before opening any other file with a tour in it.
