Le billet de Matt Korda est fort intéressant.
Although blurring out specific sites is certainly unusual, it is not uncommon for satellite imagery companies to downgrade the resolution of certain sets of imagery before releasing them to viewing platforms like Yandex or Google Earth; in fact, if you trawl around the globe using these platforms, you’ll notice that different locations will be rendered in a variety of resolutions. Downtown Toronto, for example, is always visible at an extremely high resolution; looking closely, you can spot my bike parked outside my old apartment. By contrast, imagery of downtown Jerusalem is always significantly blurrier; you can just barely make out cars parked on the side of the road.
As I explained in my previous piece about geolocating Israeli Patriot batteries, a 1997 US law known as the Kyl-Bingaman Amendment (KBA) prohibits US companies from publishing satellite imagery of Israel at a Ground Sampling Distance lower than what is commercially available. This generally means that US-based satellite companies like DigitalGlobe and viewing platforms like Google Earth won’t publish any images of Israel that are better than 2m resolution.
Foreign mapping services like Russia’s Yandex are legally not subject to the KBA, but they tend to stick to the 2m resolution rule regardless, likely for two reasons. Firstly, after 20 years the KBA standard has become somewhat institutionalized within the satellite imagery industry. And secondly, Russian companies (and the Russian state) are surely wary of doing anything to sour Russia’s critical relationship with Israel.
My complete list of blurred sites in both Israel and Turkey totals over 300 distinct buildings, airfields, ports, bunkers, storage sites, bases, barracks, nuclear facilities, and random buildings—prompting several intriguing points of consideration:
• Included in the list of Yandex’s blurred sites are at least two NATO facilities: Allied Land Command (LANDCOM) in Izmir, and Incirlik Air Base, which hosts the largest contingent of US B61 nuclear gravity bombs at any single NATO base.
• Strangely, no Russian facilities have been blurred—including its nuclear facilities, submarine bases, air bases, launch sites, or numerous foreign military bases in Eastern Europe, Central Asia, or the Middle East.
• Although none of Russia’s permanent military installations in Syria have been blurred, almost the entirety of Syria is depicted in extremely low resolution, making it nearly impossible to utilize Yandex for analyses of Syrian imagery. By contrast, both Crimea and the entire Donbass region are visible at very high resolutions, so this blurring standard applies only selectively to Russia’s foreign adventures.
• All four Israeli Patriot batteries that I identified using radar interference in my previous post have been blurred out, confirming that these sites do indeed have a military function.
