| Abstract: | TIN is basis of many kinds of surface analysing in GIS.The paper presents a effective algorithm of producing and storing TIN through analysing data structure of TIN on ARC/INFO system. Comparing the same algorithm of ARC/INFO system，the algorithm has mainly two characteristics: (1)speeding producing TIN;(2)reducing redundant data. |
