Geodetic Caluclator - Wrong distance for points on geodetic curve
-----------------------------------------------------------------
Key: GEOT-2716
URL: http://jira.codehaus.org/browse/GEOT-2716
Project: GeoTools
Issue Type: Bug
Components: core referencing
Affects Versions: 2.4.5
Environment: winxp, java 1.5.0_11
Reporter: Katrin Lasinger
Attachments: GeodeticCalculatorTest.java
When computing a geodetic curve the distance between the points on the curve is
wrong.
The problem seems to be in the method "getGeodeticCurve(final int
numberOfPoints)":
deltaDistance (distance between steps) = distance / (numberOfPoints+1)
loop: for (int i = 1; i < numberOfPoints; i++)
the last point before the destination point is not calculated or the distance
between the points is to short
current curve (numberOfPoints = 3):
o---o---o------o
correct curve (extend deltaDistance to distance / numberOfPoints):
o----o----o----o
or (add one extra point with running to loop one more time (for (int i = 1; i
<= numberOfPoints; i++)):
o---o---o---o---o
