Future ideas
- transfer curve computation to JavaScript
- implement normal mode:
- click on point selects point
- point: show lat, lon and "Delete point" button (key Backspace)
- drag point selects it
- add intermediate point selects it
- default selected point: last point
- main tabs:
- Project: name+author, description, curve list, curve+point Properties, Legend
- Colors: select colormap and map background tiles
- Help: help texts
- curvature plot preview over distance with point "sync"
- split curve at selected point
- join curves: select endpoint of one curve, click merge, select endpoint of another curve
- switch curve direction
- altitude:
- set altitude of control points:
- value above sea:
float - interpolate:
"auto"(linear interpolation using altitude from other points) - at ground level:
"ground" - value above ground level:
{"ground": float}
- value above sea:
- pass altitude to API as float value
- use altitude when generating spline, compute slope
- get ground level of curve from an elevation API:

- compute ground level of resulting curve
- bridge: curve > 6m over ground (bright blue hairline on right curve side)
- tunnel: curve > 6m under ground (brown hairline on left curve side)
- display plot: curve altitude compared to ground altitude over distance
- set altitude of control points:
