"It's not like you have the exact longitude and latitude of each strike," said Peter Bergen, a CNN national-security analyst.
"As an art project, this (Dronestagram) is interesting," Bergen said. "As a piece of actual journalism ... it seems quite off."
Bridle also uses information from the Bureau of Investigative Journalism, a British independent nonprofit organization which compiles local reports of drone strikes in Pakistan, Yemen and Somalia.
The debate over the use of attack drones will no doubt continue, even as U.S. troops continue to draw down in places like Afghanistan, reducing the number of combatants apt to encounter militants face-to-face.
And Bridle says he'll continue trying to put people at the scene of the strikes -- even if it's only through the screens of their smartphones, tablets or desktop computers.
"It's about trying to make it literally visible," he said. "The very nature of this kind of warfare makes the perpetrators, the victims, the landscape, essentially invisible."
