Potential Misleading Name or Behavior of LengthIndexedLine#extractPoint(double)

[MariiaSaltykova]

The expected behavior of the method org.locationtech.jts.linearref.LengthIndexedLine#extractPoint(double) is to return the coordinate of the point on the line at the given index. However, the actual result is the coordinate corresponding to a LinearLocation for the specified length along the linear geometry. This is because the method internally uses org.locationtech.jts.linearref.LengthLocationMap#getLocation(org.locationtech.jts.geom.Geometry, double).

Therefore, there are two possible issues:

1. The name and documentation of LengthIndexedLine#extractPoint(double) are incorrect or misleading.
2. The behavior of LengthIndexedLine#extractPoint(double) does not match its intended or described purpose.

I agree that the word index can be misunderstood to assume to mean something that points to a position in a list [of coordinates] (it is however a floating point number so that would never work).
In this case index is a length hence the name of the class LengthIndexed...
