Largest area of city of Rhodes, in a map composition generated from a macro language file (upper left 
window) & visualised in a window as a whole (lower right) & in several zoomed parts (main city upper center & a legend part upper right). The map can be converted to a graphic file or be plotted directly. Some relevant issues critical for the end-user : Are the methods for compositioning a map (text commands & / or tools) convenient & easy-to-learn? Are there enough tools & user interface features for legend creation? Are the colours on the screen similar to the plotted ones?
