主 题:Symbol symbol matching powerful mutual resolve convenient hence polygon Petroleum
摘 要:Symbols are considered as the language of a map;hence,accurate understanding of the meaning of symbols is crucial when obtaining geographical information from a map: the symbolisation of spatial data is of key importance in cartography.A geographical information system(GIS) provides a convenient mapping platform and powerful functions for spatial data symbolisation,while the presence of various mapping standards impedes the understanding of maps and sharing of map *** the other hand,the available GIS platforms find it difficult to deal with automatic conversion between maps and different mapping *** resolve this problem,an approach for symbol recognition and automatic conversion is proposed,and a conversion system based on the approach and the Arc GIS Engine platform is developed to realise automatic conversion between maps produced based on different mapping *** test these conversion effects of the proposed system,the petroleum sector is chosen as the research field and the mutual conversion of a map in practical work among the three mapping standards(*** Chinese Petroleum,Shell and USGS standards) governing this field is taken as a *** results show that the conversion system has a high conversion accuracy and strong applicability.
