Warp regular matrix map to projected graticule mesh
Syntax
h = meshm(map,maplegend) h = meshm(map,maplegend,PropertyName,PropertyValue,...) h = meshm(map,maplegend,npts) h = meshm(map,maplegend,npts,alt) h = meshm(map,maplegend,npts,PropertyName,PropertyValue,...) h = meshm(map,maplegend,npts,alt,PropertyName,PropertyValue,...)
Description
This command warps a regular matrix map to a graticule mesh, which is itself projected according to the MapProjection property of the current map axes. 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 very few graticules points in the longitudinal direction, while complex curve-generating projections require more.
h = meshm(map,maplegend) projects the regular matrix map onto the current map axes. The handle, h, of the displayed surface can be returned.
h = meshm(map,maplegend,npts) specifies the resolution of the graticule grid. The input npts is of the form [latitude-points longitude-points]. The default value of npts is [50 100] (the graticule has 50 vertices in the latitude direction and 100 vertices in the longitude direction).
h = meshm(map,maplegend,npts,alt) sets the z-axis altitude of the graticule mesh. alt can be a scalar, in which case the map is plotted on a z = alt plane, or alt can be a matrix of size(alt) = npts, in which case the graticule mesh is plotted in 3-D.
h = meshm(map,maplegend,PropertyName,PropertyValue,...) allows the input of property/value pairs to control the surface object properties. Any property supported by the standard MATLAB command surface except XData, YData, and ZData can be altered in this manner.
