Research On GIS Data Quality Control And Data Format Transformation

This paper mainly researches the meanings, contents and methods of data quality control and data format transformation, Now, some GIS software are provided for the functions of data check and data processing on 3D data, attribute data, spatial topology relationship, and so on, which greatly decrease the problems of data quality from human-machine interactive interfere, As for data quality control, these methods are not enough, Thus, it is important to make data quality control, The geographical data is the key and the core of GIS application . Due to many GIS software platforms, Complicated data structures, different and continuous developing models in GIS, Realizing the transformation among some kinds of data is always an important problem in the development of GIS application in recent years. In this article, based on the study of Geo-spatial data transformation format, the following contents are studied:1: Analyzed contents and methods of data quality control in GIS 2: Studied the compatibility between the vector data transformation format and shape file data format.3: This paper tried to establish data quality control and workout data transformation procedure by making use of oriented-object idea and process accidence realizes.At last, the result of the researching and studying is summarized and the future development tendency is looked forward to in this article.
