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].

    • isAllInBounds

      public boolean isAllInBounds()
      Deprecated.
      Description copied from interface: ILcdProjection
      If all geodetic coordinates (l ,j ) are projected (visible) by an ILcdProjection and all (x,y ) coordinates are bounded this is true. All ILcdProjection objects have bounded (x,y ) coordinates because the projection is cut off if necessary.

      isContinuous in interface ILcdProjection
      Overrides:
      isContinuous in class ALcdTransverseCylindrical
