Abstract

GIS data sharing is an important content in field of GIS research.Commonly,people mixed GIS data conversion and map data conversion,that complicates the problem of GIS data conversion.In this article,research of these two data conversion methods is separated.Aimed at map data conversion,the author put forward direct conversion,check list conversion and procedural conversion methods.Aimed at GIS data conversion,the author put forward separate-indirect conversion method.First,separate-indirect conversion method converses GIS data into spatial data file and attribute data file;second,spatial data file and attribute data file are joined together to an GIS data,after two files switch to target software respectively.
