getInverseTransformation

getInverseTransformation(projection: Projection): ProjectionTransform

- Defined in lib/Projection.ts:85
Get the inverse transformation from this Projection to the EPSG code. Each thread of execution should have it's own transformation.

Parameters
- projection: Projection
  
  projection
Returns ProjectionTransform

transform

getInverseTransformationTo

getInverseTransformationTo(authority?: string, code: string | number): ProjectionTransform

- Defined in lib/Projection.ts:115
Get the inverse transformation from this Projection to the EPSG code. Each thread of execution should have it's own transformation.

Parameters
- Default value authority: string = ProjectionConstants.AUTHORITY_EPSG
```
       coordinate authority
```
- code: string | number
```
       coordinate code
```
Returns ProjectionTransform
