TurfConstants (kits-turf API)

java.lang.Object
- ai.nextbillion.kits.turf.TurfConstants

```
public class TurfConstants
extends java.lang.Object
```
This class holds the Turf constants which are useful when specifying additional information such as units prior to executing the Turf function. For example, if I intend to get the distance between two GeoJson Points using TurfMeasurement.distance(Point, Point, String) the third optional parameter can define the output units.
Note that TurfConversion.convertLength(double, String, String) can be used to transform one unit to another, such as miles to feet.

public static final java.lang.String UNIT_NAUTICAL_MILES
```
    The nautical mile per hour is known as the knot. Nautical miles and knots are almost universally used for aeronautical and maritime navigation, because of their relationship with degrees and minutes of latitude and the convenience of using the latitude scale on a map for distance measuring.

    The kilometer (American spelling) is a unit of length in the metric system, equal to one thousand meters. It is now the measurement unit used officially for expressing distances between geographical places on land in most of the world; notable exceptions are the United States and the road network of the United Kingdom where the statute mile is the official unit used.
    In many Turf calculations, if a unit is not provided, the output value will fallback onto using this unit. See UNIT_DEFAULT for more information.
