Overview

Specifies where the top, bottom, right, and left sides of a bounding box for the ground overlay are aligned. Values for north, south, east, and west are required.

  • north (required) Specifies the latitude of the north edge of the bounding box, in decimal degrees from 0 to ±90.
  • south (required) Specifies the latitude of the south edge of the bounding box, in decimal degrees from 0 to ±90.
  • east (required) Specifies the longitude of the east edge of the bounding box, in decimal degrees from 0 to ±180. (For overlays that overlap the meridian of 180° longitude, values can extend beyond that range.)
  • west (required) Specifies the longitude of the west edge of the bounding box, in decimal degrees from 0 to ±180. (For overlays that overlap the meridian of 180° longitude, values can extend beyond that range.)
  • rotation (optional) specifies a rotation of the overlay about its center, in degrees. Values can be ±180. The default is 0 (north). Rotations are specified in a clockwise direction.
