| Abstract: | SVG is a language for describing two-dimensional graphics. It is attention-greeting in WebGIS domain for its different merit. However, the problem that how to dynamically publish SVG graphics by the spatial data management engine is not settled. A method is proposed to publish SVG on Oracle Spatial. Some important technologies are introduced, such as the special spatial object coordinates transform, the relationship between SDO_GEOMETRY and SVG,the method to transform SDO_GEOMETRY to SVG, the switch from projection coordinates to screen coordinates. |
