GPSograph Instructions [ i ]

Reset View
This resets the view to the default settings.

View Mode
Toggle between perspective and orthographic view.

Shadows
Toggle on/off. The shadows are projected to mean sea level from above.

Target
Toggle on/off. Represents the point about which the drawing swivels and indicates the scale and the orientation of the drawing.
The rings at the base are calibrated as distance from the centre, and the arrow points North.

Viewing Tools:
Click to select a tool, then click anywhere on the image, hold down and drag.

Swivel
Rotates the GPS drawing by changing the bearing and inclination.
The movement pivots on the Target.

Pan
Moves the centre of the view in accordance to the mouse movements.
The longitude and latitude change in synchrony.

Zoom
Zoom and View Distance: Vertical mouse movement changes the proximity of the viewer to and from the centre of the image.
Horizontal mouse movement increases and decreases the focal length of the image.
The zoom readout is based on a 35mm SLR camera.

Climb/ Descend
Moves the centre of view up or down.
Useful for measuring the height of a particular trackpoint with the Target.

Altitude Exageration
Turn the GPS drawing into an alpine georama with a click on and click-hold-drag of this tool.

Stereo View
For this tool to work you will need a pair of red/blue anaglyphic glasses.
The stereoscopy, or 'cleavage' of the image is controlled by the horizontal cursor movements.
Dragging the mouse up and down will make the image appear to recede into and pop out of the screen.
A bit of tweaking should allow for most people's eyesight.

*While using some of the buttons the resolution drops to compromise the refresh rate.
