Transverse Mercator Snyder

This projection is based on the description and formulae in John P. Snyder's Map Projections: A Working Manual (U.S. Geological Survey Professional Paper 1395), pp. 60-64. These formulas have been superseded by more precise versions. There are, however, some instances where users may want to use the older, less precise formulas (for example, if the results will be compared to old data).

The "Transverse Mercator Snyder" projection has the following parameters:

• Longitude of the Central Meridian

• Latitude of the Origin of the Projection

• Scale Reduction Factor at the Center of the Projection

• False Easting

• False Northing
