| Abstract: | The map projective transformation is a very important approach of the geospatial data handling for the digital mapping and GIS.Besides,the polynomial transformation is one of the most popular and effective method in the map projective numerical transformation.The influencing factors on the accuracy of map projective polynomial transformation were proposed and analyzed intensively by calculating data.Some conclusions for enhancing the accuracy of map projective polynomial transformation were given lastly. |
