Load elevation raster data and a geographic cells reference object. Display the data using a contour plot on a world map. Then, create a legend in the lower-right corner of the map. Specify the contour elevations as meters.
Contour matrix, specified as a matrix with two rows. The first row
represents longitude data and the second row represents latitude data. You
can create a contour matrix by using contourm, contour3m, or contourfm.
h — Handle of contour patches hggroup
Handle to the contour patches displayed on the current axes, returned as
an hggroup. You can get a
handle to contour patches by using contourm, contour3m, or contourfm.
loc — Location 0 (default) | 1 | 2 | 3 | 4 | -1

unitstr — Text to append character vector | string scalar
Text to append to each entry in the legend, specified as a character
vector or string scalar.
labels — Labels cell array of character vectors | string array
Labels in the legend, specified as a string array or cell array of
character vectors. labels must have the same number of
entries as the line children of h.
