1. In order to plot a rectangle on the matlab basemap ‘topographic’, use the below code.

xRec = [44.56 44.51 44.51 44.56 44.56];
yRec = [-72.73 -72.73 -72.63 -72.63 -72.73];
geoplot(xRec, yRec,'r','LineWidth',5);
geobasemap('landcover')                   %  Here, ‘landcover’ is the basemap

2. To know the elevation of a point on the basemap, you can refer to "getElevations” which is one of the several submissions in MATLAB File Exchange on MATLAB Central which is a forum for our product users to interact, exchange information and knowledge, without MathWorks' involvement.

Feel free to contact the author of this submission directly for specific questions about the implementation.
