WebGeographic coordinate systems (GCSs) use a three-dimensional ellipsoidal surface to define locations. The coordinates are based on angles from the center of the Earth to the surface. Typically GCSs use latitude and longitude specified in degrees. The coordinates derived from a GPS device are returned in a GCS named WGS84 (WKID=4326). WebThe coordinate system is controlled by the QPainter class. Together with the QPaintDevice and QPaintEngine classes, QPainter form the basis of Qt's painting system, Arthur. QPainter is used to perform drawing operations, QPaintDevice is an abstraction of a two-dimensional space that can be painted on using a QPainter, and QPaintEngine provides the interface … navy federal credit union home refinance
