Based on the introduction of image identification,this paper puts forward the method of grid conversion and then establishes the relationship between the image coordinate and the plane coordinate.

In this paper,NTv2 is deemd as the preferable one according to the comparison and analysis on two formats,and then it is made as a reference,the concrete format of grid file which is used in the grid coordinate transformation facing CGCS2000 is studied and the design sample is provided,which is based on the case of the transformation from BJS54 to CGCS2000.

In order to improve transformation accuracy,grid coordinate transformation is used to fit residuals further,in which covariance function and multi-quadric function prediction model are respectively adopted to predict the coordinate correction of grid node.

NET,then offers the programme for format transforming,image plaster an.

It illuminated the rules of SC Transform and Format Transform of Eg-TS and E1-TS.

This paper primarily describes the definition of general quick-view data imaging format,processing of data format transformation and general multifunctional image display components and so forth,and proves the feasibility of this technology via implementation of real system which correctly processed various remote sensing data from simulation source.
