- org.locationtech.spatial4j.context.SpatialContext

Direct Known Subclasses:

JtsSpatialContext
```
public class SpatialContext
extends Object
```
This is a facade to most of Spatial4j, holding things like DistanceCalculator, ShapeFactory, ShapeIO.
If you want a typical geodetic context, just reference GEO. Otherwise, You should either create and configure a SpatialContextFactory and then call SpatialContextFactory.newSpatialContext(), OR, call SpatialContextFactory.makeSpatialContext(java.util.Map, ClassLoader) to do this via configuration data.
Thread-safe & immutable.

    Is the mathematical world model based on a sphere, or is it a flat plane? The word "geodetic" or "geodesic" is sometimes used to refer to the former, and the latter is sometimes referred to as "Euclidean" or "cartesian".
  - normX
```
@Deprecated

  - toString
```
@Deprecated
public String toString(Shape shape)
```
    Deprecated.
    
    Writes the shape to a String using the old/deprecated LegacyShapeWriter. The JTS based subclass will write it to WKT if the legacy format doesn't support that shape. Spatial4j in the near future won't support writing shapes to strings.

    shape - non-null

    non-null
