Coordinates

Geo locations in Navmii SDK is represented as NMMapCoordinates class instances. As expected, it has two properties: latitude (takes values from -90 to 90) and longitude (takes values from -180 to 180) . You can create NMMapCoordinates instances in two ways: via instance or class methods.

//creates a NMMapCoordinates object representing London coordinates
NMMapCoordinates *mapCoordinates = [[NMMapCoordinates alloc] initWithLongitude:-0.12574
									    						   andLatitude:51.50833];
//or, alternatively
NMMapCoordinates *mapCoordinates = [NMMapCoordinates mapCoordinatesWithLongitude:-0.12574
																	 andLatitude:51.50833];

Navmii SDK also has NMMapRectangle class representing a rectangle area on the map. It can be created throughout initWithMinLongitude:minLatitude:maxLongitude:maxLatitude: and initWithLeftTop:andRightBottom: instance methods and mapRectangleFromCoordinates: class method. The later creates a NMMapRectangle surrounding all the coordinates passed as the argument.

//creates a NMMapRectangle with four double values
NMMapRectangle *mapRectangle = [[NMMapRectangle alloc] initWithMinLongitude:minLongitude
																minLatitude:minLatitude
															   maxLongitude:maxLongitude
																maxLatitude:maxLatitude];
//or, alternatively
NMMapCoordinates *leftTop = [NMMapCoordinates mapCoordinatesWithLongitude:minLongitude
															  andLatitude:maxLatitude];
NMMapCoordinates *rightBottom = [NMMapCoordinates mapCoordinatesWithLongitude:maxLongitude
																  andLatitude:minLatitude];
NMMapRectangle *mapRectangle = [[NMMapRectangle alloc] initWithLeftTop:leftTop
														andRightBottom:rightBottom];

//creates a NMMapRectangle bounding all the coordinates in coordinatesArray
NMMapRectangle *mapRectangle = [NMMapRectangle mapRectangleFromCoordinates:coordinatesArray];
