  • This paper introduces briefly the principle of coordinate transformation between the spatial information multi-grids. By comparing the coordinate accuracy of the affine transformation and rigorous coordinate transformation, it is found that the coordinate accuracy of affine transformation instead of rigorous coordinate transformation is higher than map presentation accuracy in the grid of proper scale. The experimental results provide the scale criterion for both the division of spatial information multi-grid and the manner of spatial data organization which is adapt to spatial coordinate transformation.

Abstract: This paper introduces briefly the principle of coordinate transformation between the spatial information multi-grids. By comparing the coordinate accuracy of the affine transformation and rigorous coordinate transformation, it is found that the coordinate accuracy of affine transformation instead of rigorous coordinate transformation is higher than map presentation accuracy in the grid of proper scale. The experimental results provide the scale criterion for both the division of spatial information multi-grid and the manner of spatial data organization which is adapt to spatial coordinate transformation.
