Abstract: This paper deeply discusses the data format of MapGIS and ArcGIS software, and analyze the differences of ArcGIS Geodatabase format and shapefile format, designs and implements the scheme of nondestructive and automatic conversion of data from the MapGIS platform to ArcGIS platform, effectively solves the problem in original data conversion scheme that information is missing and note can't render. Through the contrast experiment shows that the scheme has higher accuracy and better time performance from MapGIS to ArcGIS Geodatabase of data transformation process than the traditional shapefile format.
