The Information Loss In Data Format Transformation Between ArcGIS And MapGIS
Abstract:The research employs the data structure, data model and data format of ArcGIS and MapGIS as breakthrough point. Meanwhile, ArcGIS standard data format, namely shapefile, and MapGIS standard data format, including .wt, .wl and .wp, are utilized as transformation base. Two transformation methods, including direct conversion and conversion with E00 intermediate format were used for Yunnan University main campus data to study the transformation feature and information mission, where the display pattern and information mission between the two softwares at spatial data and attribute information mission, as well as some example attribute fields, including string, float, double, text, image, and binary data format as research key point.
Keywords: ArcGIS MapGIS spatial data transformation GIS E00 intermediate transformation format
