Project regular data grid on map axes in z = 0 plane
h = pcolorm(...)
a surface to represent the data grid
Z in the current
map axes. The surface lies flat in the horizontal plane with its
vectors or 2-D arrays that define the latitude-longitude graticule
mesh on which
Z is displayed. For a complete description

These limits should match the geographic extent of

Latlim is a two-element vector of
lonlim has the form:
A latitude-longitude graticule of size 50-by-100 is constructed.
FaceColor property is

Load elevation raster data and a geographic cells reference object. Then, display the data as a surface.

This function warps a data grid to a graticule mesh, which is
projected according to the map axes property
The fineness, or resolution, of this grid determines the quality of
the projection and the speed of plotting it. There is no hard and
fast rule for sufficient graticule resolution, but in general, cylindrical
projections need fewer graticule points in the longitudinal direction
than do complex curve-generating projections.
