Ellipse Setting Out

WARNING: This app will NOT work on Android 5.0 and above devices!

Do you need to do Setting-Out for ellipse-shaped house or swimming pool and it must be hi-precision setting-out and definitely not an arc (simple radius) but ellipse? That is not going to be a problem for anyone with "Ellipse Setting Out" in his pocket.
With "Ellipse Setting Out" you can calculate coordinates along ellipse line from known values of the two "radius", coordinates of the center point, and coordinates for "backsight" (beginning of the R1 [X0,Y0] and its end point [Xbs,Ybs]).
Enter desired distance along R1, from center point [X0,Y0] towards "backsight" and get calculated coordinates for Four points in each quarter of the ellipse at such distance. Enter next distance from [X0,Y0] towards BS, and get next 4 points.
In the example shown at https://sites.google.com/site/settingoutapps/ for distances:
- at 1 unit you get coordinates for points: № 1, 54, 55, 108;
- at 2 unit you get coordinates for points: № 2, 53, 56, 107 etc...
You can start from distance equal 0 and finish at distance equal R1.
With "Ellipse Setting Out" you can make as many points as you wish, to make sure your line is True Ellipse Line.

Program works with Decimal Units.
