Neat but not impressive compared with what's possible today.

Those old KH-11 degraded images are pictures reprinted from a magazine (Janes).

The max resolution in ideal conditions of the late 70's birds was about a inch (3 cm or so) from LEO after processing several look angles (Superresolution techniques). Like the James Webb telescope modern IMINT optics have dynamic image aberration correction for improved resolution and clarity.

You can buy 30 cm resolution images today off the commercial market.

Images with different resolutions, based on aerial photography.

A building explosion in northern Japan's Sapporo that injured 42 people on the weekend occurred after employees of a real estate office emptied about 120 deodorizer spray cans, a company operating the office said Tuesday.

The employees tried to empty 120 out of 160 new spray cans for disposal without knowing the gas was flammable, said Taiki Sato, the chief of the Hokkaido unit of Apamanshop Leasing Co. The explosion occurred after employees turned on a water heater.
