Vectors
Cartesian and Polar co-ordinates are two different methods used to describe the magnitude and direction of a vector.
Cartesian co-ordinates are the two or three-dimensional linear distances (x,y,z) from a known point or origin to the end of a vector.
Polar co-ordinates are the angular orientations (α & β) of a vector along with its length (V) defined from a known point or origin.
Map Co-Ordinates
Latitude-Longitude angles and UTM distances are used to define a point on a curved or (flattened) surface.
Latitude and Longitude are the vertical and horizontal angles (respectively) that define a point on the surface of a sphere (such as a planet) with respect to a fixed vertical meridian (Longitude) and a fixed horizontal meridian (Latitude). These meridians can also be used as datums from which to define surface distances to the same point.
Coordinates converts between Cartesian and Polar vector co-ordinates and also between spherical latitude-longitude angles and UTM distances.
The co-ordinates calculator includes four calculation options; Cartesian to Polar (Vectors) & Polar to Cartesian (Vectors), Angle to Distance (Lat-Long) and Distance to Angle (Lat-Long).
