Abstract: Snow/ice stratigraphic profile is one of the traditional and important research fields in glaciology. The profile drawn by hand, however, is a tough job. Drawing Software for Snow/Ice Stratigraphic Profile is developed by means of the Object Oriented Programming (OOP) Visual Basic (VB). This paper introduces the major functions, designing process and realizing methods of the drawing software, and presents the key techniques and aspects that should be paid attention to during the software development. Moreover, the paper also proposes the idea for complete development of this drawing system. Legend database is a key aspect in this software designing. Comprehensively considering all kinds of snow/ice types divided in snow-ice research previously, the authors designed and drew a relatively complete set of legends in the software. The functions of the software include the stratigraphic profile drawing, edition and data management, which can help researchers draw the stratigraphic profile (including the scale, stratigraphic figure, text note and legend) efficiently in a computer. In addition, the database technique is used to manage drawing data, which make the figure drawing convenient and efficient. It is also convenient to preserve, exchange, handle and make use of the drawing data.

Key words: snow/ice stratigraphy, drawing software, legend, database
