About Roller Derby Track Layout

The application displays measurements (In feet, Inches and Meters) between any two selected points on a Roller derby Track.

It displays a Roller Derby Track on the screen with 45 key Points as blue dots. By selecting any two blue dots the application will provide three measurements:

1) The straight line distance in red
2) The vertical distance between the two points in green
3) The horizontal distance between the two points in blue

The horizontal and vertical distances are useful to get from point A to point B if the straight line distance is not parallel / perpendicular to the hall walls but at an angle. By navigating via the horizontal and vertical distance which are parallel / perpendicular to the hall walls, this will ensure a much more accurate result.

The track displayed has also been rotated through 3.27 degrees (as well as all the 45 key points). This results in a track where the outside oval now has it's straights parallel with the hall walls. This saves 2ft in width and is useful if the hall is tight on space. It is the inside track that is now skewed. This means that the inside center line defined by the two inside track markers is now at an angle of 3.27 degrees. It is the line between the two outer track centers that now runs vertically.

Any key point can be selected by touching the screen near it. You do not have to touch the dot exactly. The software works out which key point is the nearest to the place you touched. The first touch will select the first point which will turn red. The second touch will select the second point which will also turn red, but the software will also display the three distances specific to those two points. Another touch anywhere on the screen will clear it and you are now free to select any other two points.

The application has been tested on a screen resolution of 320 * 480. It works but you have to be precise when selecting a point on the screen this small. Less precision is required on devices with larger screens.

The distances is meters is calculated / displayed to a 0.1 of a mm, or 0.0001 of a meter. The distances in Feet and inches are displayed to the nearest 1/8th of an inch. I did try displaying the distance to the nearest 1/64th of an inch. But I found this confusing when most tape measures are marked in 1/8th of an inch.
