Function getLineLength

getLineLength(feature, units?): number
JMap.Geometry.getLineLength

Works for feature having geometry equals to LineString or a MultiLineString.

It returns the line length in the desired units (default in kilometers).

Throw an error if the provided feature geometry is not a LineString or a MultiLineString.
Parameters
- feature: Feature<LineString, GeoJsonProperties> | Feature<MultiLineString, GeoJsonProperties>
  The LineString or MultiLineString feature to measure.
- Optional units: JGEOMETRY_UNITS | JMAP_DISTANCE_UNITS
  Can be "degrees", "radians", "miles", or "kilometers" (default)
Returns number
Example
```
const line = ...

// The method will return the line length in kilometers
JMap.Geometry.getLineLength(line)

// The method will return the line length in miles
JMap.Geometry.getLineLength(line, "miles")
```
