| Abstract: | :According to the positioned data and the code of the symbols in the geo-da-tabasc, the principles and the methods of symbolising have been introduced by using the symbol-data in the rast symbol-base. The symbolled maps, in which the rivers' representation can vary thick or thin, are beautiful and vivid0 This simple method has the advantage of not only being in common use highly and independant of data and programs. |
