KEY TECHNIQUES RESEARCH OF AUTOMATIC CARTOGRAPHY OF ACTIVE FAULT

Mass of data in geochemical,geophysical,geological,seismological and other aspects were collect- ed for the national active fault database system in the Tenth Five-Year Plan. How to make use of these mass of data to produce thematic map for government’s decision making in urban development plan- ning,land use,significant engineering site selection and providing the scientific basis for urban earth- quake resistance and disaster mitigation has become an issue worth studying. Automatic cartography solves this problem well. By summarizing,we find that most of present researches in automatic cartography care much a- bout cartography process itself,rarely involve property and spatial data inspection. Thus,it is hard to ensure the accuracy of data and may lead to a drop in quality of automatic cartography. Firstly,this pa- per discusses the process of automatic cartography. Secondly,considering the actual situation of urban active fault detecting project,we propose to add inspection of automatic cartography and topology check to guarantee the quality of cartography. Thirdly,further research is done in the principle of auto- matic matching and topology checking to develop a feasible process for automatic matching and topolo- gy checking. Finally,a system is designed to realize the function of automatic matching. The techniques and methods used in this system have important reference value in mapping auto- mation in other areas,such as climate,geography,resources and land use,etc.
