Using Splines for Area Features #793
Description
When creating a feature like a subducting plate, the intersection between the subducting plate feature and the oceanic plate feature is not always smooth. This is because the subducting plate feature creates the trench using an interpolated spline, and the oceanic plate feature is created using piecewise linearly. This creates a gap between the two features that is visually annoying at best (see image below) and could interfere with models results at worst (since the composition is not necessarily what it should be in this gap). This could be fixed by creating features like oceanic plates and continental plates with interpolated splines, however one would just have to be careful that the same spline is used for the intersection between two features.
