Abstract

A method for automatically verifying the accuracy of an electronic map, said method involving an XORing operation for raster data produced by scanning an original map and vector data finally produced based on the raster data, and a filtering operation for data resulting from the XORing operation. The method includes the steps of scanning an original map, thereby producing raster data, digitizing the raster data, thereby producing vector data, transforming the vector data into raster data, comparing the raster data transformed from the vector data with the original raster data by use of a function of similarity involving an exclusive ORing operation, and removing noise existing in the original raster data by a filtering operation. In accordance with this method, it is possible to reduce the verification time and costs while improving the accuracy of the verification.
