A tool that prints the S2 cell for a given coordinate, prints cell info, as well as generates KML visualizations of cell parents and boundaries.
$ go get github.com/dsoprea/go-s2
The following commands are obviously run from "${GOPATH}/src/github.com/dsoprea/go-s2".
Just encode the location into an S2 cell token:
$ go run main.go cell --latitude 42.533333 --longitude -83.146389
883b2d2febf80c13
Encode, but print in the binary representation:
$ go run main.go cell --latitude 42.331389 --longitude -83.045833 --to-binary
1000100000111011001011010010111111101011111110000000110000010011
Print as a specific level (not as the default level-30 leaf cell):
$ go run main.go cell --latitude 42.331389 --longitude -83.045833 --to-binary --level 28
1000100000111011001011010010111111101011111110000000110000010000
Print the parent hierarchy (all levels, from leaf and downwards but excluding the face):
$ go run main.go parents --cell-token 883b2d2febf80c13

Generate KML showing all parents along with cell bouundaries (at or less than level 15):
$ go run main.go parents_kml --cell-token 883b2d2febf80c13
When the KML is opened in Google Earth, it will render something like:
