I love having access to online satellite imagery. I can use it to find landmarks, interesting geological features, and military bases! That last item is why many nation states have developed a love-hate relationship with satellite imagery. While the technology is convenient for finding enemy military bases, it’s inconvenient because it allows the enemy to find your military bases.
Yandex decided it wanted to be helpful to several national militaries. Before making its satellite imagery publicly available, Yandex decided to blur out a bunch of military bases. However, in so doing it showed everybody exactly where a bunch of previously unknown military bases were:
A Russian online mapping company was trying to obscure foreign military bases. But in doing so, it accidentally confirmed their locations—many of which were secret.
Yandex Maps, Russia’s leading online map service, blurred the precise locations of Turkish and Israeli military bases, pinpointing their location. The bases host sensitive surface-to-air missile sites and facilities housing nuclear weapons.
The Federation of American Scientists reports that Yandex Maps blurred out “over 300 distinct buildings, airfields, ports, bunkers, storage sites, bases, barracks, nuclear facilities, and random buildings” in the two countries. Some of these facilities were well known, but some of them were not. Not only has Yandex confirmed their locations, the scope of blurring reveals their exact size and shape.
