The OpenMap Viewer loads properties from an
openmap.properties file. It
searches for this file in two locations: 1) in the JAR file or class
directory, 2) in the user's home directory. If it finds the file in
any of these places, it loads the properties from it, overriding
previous settings. We suggest that you copy the
openmap.properties file from the openmap directory to your
home directory, and edit the settings to your own liking.
