Subject [jira] [Updated] (SIS-453) GeodeticCalculator.toGeodesicPath should build ISO curves
Date Tue, 14 May 2019 16:00:00 GMT


Martin Desruisseaux updated SIS-453:
    Issue Type: Improvement  (was: Bug)

> GeodeticCalculator.toGeodesicPath should build ISO curves
> ---------------------------------------------------------
>                 Key: SIS-453
>                 URL:
>             Project: Spatial Information Systems
>          Issue Type: Improvement
>          Components: Referencing
>    Affects Versions: 1.0
>            Reporter: Martin Desruisseaux
>            Priority: Major
> {{GeodeticCalculator.toGeodesicPath2D()}} currently returns a {{java.awt.Shape}} with
two limitations: A first limitations is that we currently return a single linear, quadratic
or cubic Bézier curve, i.e. an {{java.awt.geom.CubicCurve2D}} at most. Meeting the accuracy
requirement may require to build chain of Bézier curves instead than a single one.
> A second limitation is that we return an object ({{java.awt.Shape}}) which is tied to
the {{java.desktop}} module, which may not be available or may be replaced by another module.
We can make abstraction from the geometry library by using GeoAPI interfaces derived from
ISO 19107, but those interfaces are not yet ready.
