WebThe sides of an Envelope align with the axes of its spatial reference. If the spatial reference is a geographic coordinate system, the x-coordinates relate to longitude and the y-coordinates relate to latitude. Envelopes are commonly used to represent the spatial extent covered by layers or other geometries, or to define an area of interest. Webcoordinate QML Basic Type. The coordinate type represents and stores a geographic position. This type is a QML representation of QGeoCoordinate and represents a geographic position in the form of latitude, longitude and altitude attributes. The latitude attribute specifies the number of decimal degrees above and below the equator.
