| Abstract: | The core idea of spatial information multi-grid and the coding system areintroduced in brevity,transforms among the coordinates of the spatial points,the row,column of basic grid,the level of the coding and the code of a grid are used to create multiple levels grids for map spatial data,which is fulfilled by means of Visual Basic development platform and MapObjects of ESRI of the United States. |
