## Method Documentation

geocircle circle(coordinate center, real radius)

Constructs a geocircle centered at center with a radius of radius meters.

geocircle circle()

Constructs an invalid geocircle.

See also geocircle.

`[since 5.12]` point coordToMercator(coordinate coord)

Converts a coordinate coord into a mercator coordinate and returns it.

This method was introduced in Qt 5.12.

See also mercatorToCoord.

coordinate coordinate(real latitude, real longitude, real altitude)

Constructs a coordinate with the specified latitude, longitude and optional altitude. Both latitude and longitude must be valid, otherwise an invalid coordinate is returned.

See also coordinate.

coordinate coordinate()

Constructs an invalid coordinate.

`[since 5.12]` coordinate mercatorToCoord(point mercator)

Converts a mercator coordinate into a latitude-longitude coordinate.

This method was introduced in Qt 5.12.

See also coordToMercator.

`[since 5.9]` geopath path(list<coordinate> coordinates, real width)

Constructs a geopath from coordinates and width.

This method was introduced in Qt 5.9.

See also geopath.

`[since 5.9]` geopath path()

Constructs an empty geopath.

This method was introduced in Qt 5.9.

See also geopath.

`[since 5.12]` geopolygon polygon(list<coordinate> perimeter, list<list<coordinate>> holes)

Constructs a polygon from coordinates for perimeter and inner holes.

This method was introduced in Qt 5.12.

See also geopolygon.

`[since 5.10]` geopolygon polygon(list<coordinate> coordinates)

Constructs a polygon from coordinates.

This method was introduced in Qt 5.10.

See also geopolygon.

`[since 5.10]` geopolygon polygon()

Constructs an empty polygon.

This method was introduced in Qt 5.10.

See also geopolygon.

georectangle rectangle(coordinate topLeft, coordinate bottomRight)

Constructs a georectangle with its top left corner positioned at topLeft and its bottom right corner positioned at bottomRight.

See also georectangle.

georectangle rectangle(coordinate center, real width, real height)

Constructs a georectangle centered at center with a width of width degrees and a hight of height degrees.

See also georectangle.

georectangle rectangle()

Constructs an invalid georectangle.

See also georectangle.

geoshape shape()

Constructs an invalid geoshape.

See also geoshape.

`[since 5.5]` geocircle shapeToCircle(geoshape shape)

Converts shape to a geocircle.

This method was introduced in Qt 5.5.

See also geocircle.

`[since 5.9]` geopath shapeToPath(geoshape shape)

Converts shape to a geopath.

This method was introduced in Qt 5.9.

See also geopath.

`[since 5.10]` geopolygon shapeToPolygon(geoshape shape)

Converts shape to a polygon.

This method was introduced in Qt 5.10.

See also geopolygon.

`[since 5.5]` georectangle shapeToRectangle(geoshape shape)

Converts shape to a georectangle.

This method was introduced in Qt 5.5.

See also georectangle.
