As gold leaves drifted to the ground in Central Park on Monday, a strange-looking vehicle joined the park’s stream of pedicabs, bicycles, baby carriages and skateboards. It was straight out of Roald Dahl’s imagination, at once sinister and innocent — an ungainly contraption cooked up by, say, Good Humor and the K.G.B.

It was, in fact, Google’s Trike, a panoramic camera system with nine lenses mounted on an oversize tricycle. The company, which already offers 360-degree street-level views of New York City and other cities, has turned its attention to parks, as well as other locations inaccessible by car. The Trike has been wheeling through hard-to-reach places across the globe, mapping them and then offering online Street View tours on Google Maps that let the would-be parkgoer mouse-click along a path.

Two weeks ago, the High Line was added to Google’s digital archive, along with Clearview Park Golf Course in Queens, Dyker Beach Park in Brooklyn and Pelham Bay Park in the Bronx. They joined parks in 21 other countries, from Kensington Gardens in London to Koganei Park in Tokyo.

Central Park had its star turn on Monday, when a team of cyclists began the job of maneuvering the Trike along 58 miles of paths. The leaves were in full splendor as the camera lenses captured vistas in all directions, snapping meadows and playgrounds, monuments and ball fields, as well as the occasional squirrel.
