The Arlington National Cemetery may be quite a daunting place to navigate through, especially if you do not know exactly where you need to go.

Finding a fallen hero’s final resting place will no longer be as challenging as it used to be, at least if you are the owner of an iPhone. The Arlington National Cemetery will soon become the first to have a 4G network, and a mobile app will soon be available to help visitors find a specific grave.

It will be the first such system in a federal cemetery, and is more accurate and up-to-date than those in the private sector. It was also described as a “byproduct” of an Army Inspector General investigation from a couple of years ago, which revealed double-booked gravesites, graves with no headstones, unidentified urns dumped in a mass grave, and millions of dollars worth of information management systems that were ordered but neither delivered nor installed.

In addition to the app, the modernization also covers new equipment and procedures for various needs, such as taking phone calls and burials, as well as supports the ongoing review of the cemetery’s 259,978 grave sites and urn niches.

It combines aerial photographic maps with digitized records to keep track of urns and grave sites, schedule burials (which happen at a rate of 27 per day), plan procession routes and other events, and provide access to the public to photos and maps, with 3-inch accuracy, for the more than 300,000 who are interred at Arlington.
