GeodeticCalculator - Wrong azimuth calculation
----------------------------------------------
Key: GEOT-2715
URL: http://jira.codehaus.org/browse/GEOT-2715
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 trying to compute a geodetic curve at the equator from east to west,
a wrong azimuth is calculated.
The problem seems to be in the (private) method "computeDirection":
If "dlon" (delta longitude) is < 0 a wrong calculation is done:
... Math.PI * (3 / 2) ...
(3 / 2) is computed as integer and then used with pi.
The whole computation must be performed with double precision!
