#86 Track a Package Across the U.S.

HACK

• A value of yes to signal the program to modify Openmap’s properties. If

you’re curious about the Openmap properties file, there’s plenty of

information about it at http://openmap.bbn.com/cgi-bin/faqw.

py?req=show&file=faq06.004.htp.

$ java -cp . org.rajsingh.maphacks.shipment.PackageTracker \

<path to places.txt> <path to a new file name> yes

The Results

Remember that we started this hack wanting to put our package “on the

map”? Well, we’re finally there. Since we automatically added our data to

Openmap’s properties file, all we need to do is run the program. Your final

result should look something like Figure 7-7.

See “Java-Based Desktop Mapping with Openmap”

[Hack #66] to learn how to

get state boundaries on your map as well.
