Measure tool
To measure distances click on any locations on the surface of the globe. With each click a line is drawn and distance is shown in numbers next to the current measure point.
Continuing in this manner the added distances will be displayed along with the previous one.
When choosing another tool the measure lines will be deleted. They cannot be saved at the time being.
The globe can be rotated while measuring by simply holding down the left mouse button and moving the mouse. After releasing the mouse button you can proceed measuring
Use the option "orthodrome" to measure the absolute linear distance between locations.
"Loxodrome" describes a measuring method commonly applied in nautical navigation using a compass. It does not measure the shortest distance. A loxodrome line crosses the meridians of the geographic coordinate system at a constant angle avoiding the dire task of having to recalulate the course of a ship all the time. Orthodrome and loxodrome measuring are almost indistinguishable at shorter distances. The difference becomes obvious when retracing the course of an ancient explorer ship going across the Atlantic Ocean compared to a modern airplane.
While measuring you can add a "great circle" around the whole globe, showing locations lying in the extended direction of the last measured distance.
You can choose the measure units either in miles or kilometers.




Pen (freehand drawing)
You can draw anywhere on the surface of the globe in order to trace a certain area or highlight objects that you want your audience to focus on. You can even do so in perspective mode - your drawing will appear right on the embossed 3D terrain. Save your drawing in a scene if you want to recall it later.
Using the pen tool is simple: Choose color, line thickness and degree of transparency, then move your mouse on the globe while holding down the left mouse button.
IMPORTANT: You can rotate the globe with the the RIGHT mouse button while you are in drawing mode.



Line tool
This function will draw straight lines between points as you click. Choose color, line thickness and degree of transparency before clicking. You can add another line that is not connected to the previous point by pressing the space bar on your computer keyboard.
IMPORTANT: You can rotate the globe with the the RIGHT mouse button while you are in drawing mode.



Area tool
Two options are available to draw areas on the globe. Choosing "freehand", the tool will act just like the pen. Encircling an area will draw a line, the space inbetween will be filled automatically as soon as you release the mouse button.
"Straight line" requires points to be set by clicking. Lines between the points are drawn automatically while at the same time the area will be filled. You can start with a new area right away when pressing the space bar on your computer keyboard
IMPORTANT: You can rotate the globe with the the RIGHT mouse button while you are in drawing mode.
