2. Cylindrical and Pseudo-cylindrical Projections 2.6 Universal Transverse Mercator (UTM) UTM maps are needed only for high-quality maps of small regions of the globe (less than a few degrees in longitude). This is an ellipsoidal projection. Options are similar to those of the Transverse Mercator, with the addition of These are computed automatically if not specified. The ellipsoid defaults to 'normal', a spherical earth of radius 1 unit, but other options can also be chosen using the following property: For a list of available ellipsoids try m_proj('get','utm'). The big difference between UTM and all the other projections is that for ellipsoids other than 'normal' the projection coordinates are in meters of easting and northing. To take full advantage of this it is often useful to call m_proj with 'rectbox' set to 'on' and not to use the long/lat grid generated by m_grid (since the regular matlab grid will be in units of meters). UTM is an ellipsoidal projection, and both the lambert conformal conic and albers equal-area conic can be specified with ellipses if desired. This is sometime useful when you have data (e.g. from a GIS package) at scales of Canadian provinces or US states, which are often mapped using one of these projections. It is unlikely that this will be a problem in normal usage
2. Cylindrical and Pseudo-cylindrical Projections 2.7 Sinusoidal This projection is usually called "pseudo-cylindrical" since parallels of latitude appear as straight lines, similar to their appearance in cylindrical projections tangent to the equator. However, meridians curve together in this projection in a sinusoidal way (hence the name), making this map equal-area. 2.8 Gall-Peters Parallels of latitude and meridians both appear as straight lines, but the vertical scale is distorted so that area is preserved. This is useful for tropical areas, but the distortion in polar areas is extreme.
