| Abstract: | The integration of digital technology of mapping the production industry within and outside showed a tremendous advantage in the accuracy of data and map clean and so on,on the basis of in the grating topographic map made use of advanced computer technology,handling of its digital conversion to digital topographic maps,optical map correction occupies an important position.The method and step of realization of MicroStation software was illustrated simply with a project performed in topography map optical image correction area of Henan.The experiments show that this method is simple,accurate and made a foundation for the full automation of topography vectogram work.It is a valid way of optical image correction. |
