The Circuit Tools software package is designed to vastly simplify the process of extracting more performance from yourself and your car. Watch the demonstration video:
Insert your SD card containing the video and synchronised data, and select the latest file. The software then automatically detects the country, circuit and track configuration you have been driving from the database of 300+ circuits included with the package, then uses the start/finish line in the database to separate and sort the laps contained in that file.
(To download a Google Earth KML file showing all of the tracks currently in the database, click here)
The fastest lap from your latest session is automatically chosen and displayed on the graph window, and the video is moved to the start of this lap. You can then compare runs from this session, or from previous one simply by clicking on the relevant lap-time shown in the session window.
A theoretical 'ideal lap' is calculated from the best sectors in each session. To view sectors, simply click on the relevant sector, or drag the cursor over a number of sectors to show a sequence.
A very useful channel, time difference or 'Delta-T', can be displayed showing the lap-time difference around the lap between two different laps.

Circuit Tools contains a huge database of worldwide circuits and for most circuits in that database are Track overlays.
These are surveyed inside and outside edges of the track, which allow you to truly see and compare different driving lines.
Why is position comparison better than time and distance?
Time: One driver may drive around a circuit at a totally different speed to another. While one driver is still approaching a corner, another could be already on the exit - which makes true comparison difficult.
Distance: As position on the track will often differ between laps or between drivers, distance travelled even around one lap is often very different from lap to lap. This could be as a result of using differet lines, or going around the outside of a corner (and thus travelling further) due to traffic. Around long tracks this can equate to a large difference.
Therefore, if a point is picked for comparison using either of the above options, then there is a high likelihood that the two laps / drivers will be at separate points in the circuit.
Position: Using GPS position (shown in the bottom image, above right) means that it does not matter how fast you are, or what distance you have travelled. This is because the software will look at the GPS sample points and use the position data from each lap when aligning the comparison laps. If you want to compare the same point on a corner, for example, you can do it with a high degree of accuracy.
