Mercator chart convergence

Universal Transverse Mercator (UTM) and the Universal Polar Stereographic (UPS) grids. It also discusses computations for convergence from geographic positions and from grid coordinates for the UTM grid, and convergence in the Polar Stereographic projection. Both mathematical and tabular methods are illustrated for the above items. Grid convergence & point scale factor. Grid convergence is the angle at a point between true north and grid (projection) north. The point scale factor is the scale factor at a point that changes with increasing distance from the central meridian. The Universal Transverse Mercator Coordinate (UTM) system provides coordinates on a world wide flat grid for easy computation. The Universal Transverse Mercator Coordinate system divides the World into 60 zones, each being 6 degrees longitude wide, and extending from 80 degrees south latitude to 84 degrees north latitude The polar regions are excluded.

The rectilinear co-ordinates of Mercator's chart, wherein degrees of latitude "are of the earth and the consequent convergence of the continents at the poles. The transverse Mercator map projection is an adaptation of the standard Mercator projection.The transverse version is widely used in national and international mapping systems around the world, including the UTM.When paired with a suitable geodetic datum, the transverse Mercator delivers high accuracy in zones less than a few degrees in east-west extent. The convergence angle (CA) is the actual angle on a chart formed by the intersection of the Greenwich meridian and another meridian; the pole serves as the vertex of the angle. CAs, like longitudes, are measured east and west from the Greenwich meridian.
