Package google.geo.type

  • A Viewport is defined by two points, low and high, representing its southwest and northeast corners, respectively, used to specify a rectangular geographical area.

  • Latitude bounds must be within -90 to 90 degrees, and longitude bounds within -180 to 180 degrees, inclusive.

  • Specific cases like single-point Viewports, inverted longitude ranges, full longitude inclusion, and empty ranges are outlined with their conditions.

  • Both low and high points are required, and the defined Viewport area cannot be empty, otherwise, an error will occur.

Viewport

A latitude-longitude viewport, represented as two diagonally opposite low and high points. A viewport is considered a closed region, i.e. it includes its boundary. The latitude bounds must range between -90 to 90 degrees inclusive, and the longitude bounds must range between -180 to 180 degrees inclusive. Various cases include:

  • If low = high, the viewport consists of that single point.

  • If low.longitude > high.longitude, the longitude range is inverted (the viewport crosses the 180 degree longitude line).

  • If low.longitude = -180 degrees and high.longitude = 180 degrees, the viewport includes all longitudes.

  • If low.longitude = 180 degrees and high.longitude = -180 degrees, the longitude range is empty.

  • If low.latitude > high.latitude, the latitude range is empty.

Both low and high must be populated, and the represented box cannot be empty (as specified by the definitions above). An empty viewport will result in an error.

For example, this viewport fully encloses New York City:

{ "low": { "latitude": 40.477398, "longitude": -74.259087 }, "high": { "latitude": 40.91618, "longitude": -73.70018 } }

Fields
low

LatLng

Required. The low point of the viewport.
high

LatLng

Required. The high point of the viewport.
