A bunch of utilities for working with geographic data and files. This started out when I wanted to clean and analyze GPS tracks from my various devices. It moved into its own project when friends became interested. You're welcome to use them, and I believe all of the calculations are correct, but please don't complain if my function says that you ran 1.23 miles and your watch says 1.26.
There are two sub-projects:
libfor reusable library classes.utilfor specific utility programs.
The package structure starts with com.kdgregory.geoutil, followed by lib or
util. The lib package has several sub-packages:
corecontains core geographic functionality such as distance calculations and tools for managing lists of geographic points.gpxis an (incomplete) data model for the GPX file format.kmlis an (incomplete) data model for the KML file format.
To build, run mvn package from the top-level directory (or mvn install if you
plan to use the library in your own code).
The utilities are packaged as a single "uber-JAR"; to run them, use the following
command (replacing CLASSNAME with the fully-qualified classname of the utility
that you want to run):
java -cp util/target/geoutil-*.jar CLASSNAME
All of the utilities will exit with a usage message if you invoke them without command-line parameters. BEWARE that most of the utilities overwrite the original file; make a backup if you don't want this to happen.
