This is a Java implementation of the geodesic algorithms described in

The code in this directory is entirely self-contained.  In particular,
it does not depend on the C++ classes.  You can build the example
programs using, for example,

  cd inverse/src/main/java
  javac -cp .:../../../../src/main/java Inverse.java
  echo -30 0 29.5 179.5 | java -cp .:../../../../src/main/java Inverse

Building with maven is also supported (see the documentation).
