public class TLcdTransverseMercatorSPCS
extends ALcdTransverseCylindrical

Transverse Mercator SPCS projection.

Introduction

The transverse Mercator projection is an adaptation of the Mercator projection. In the transverse Mercator, the cylinder is rotated 90° (transverse) relative to the equator so that the projected surface is aligned to a central meridian rather than to the equator. This projection used for the United States State Plane Coordinate System (SPCS).

Properties

• The projection is conformal.
• The central meridian, each meridian 90° from the central meridian and the Equator are shown as straight lines.
• Other meridians and parallels are shown as complex curves.
• Scale is true along the central meridian.
• Scale becomes infinite on the sphere 90° from the central meridian.

Example

Sample code

 ILcdProjection projection =
     new TLcdTransverseMercatorSPCS(-50.0);
 

Implementation aspects

The equations of the transverse mercator projection are taken from [Snyder1987].

Checks if a ILcdPoint is inside the valid cartesian area of the projection.
