Automatic Discovery of Feature Change Based on the Database of Urban Large Scale Topographic Maps

    Abstract
  • This paperpr proposes a method to discover automatically feature change based on topographic map database, field patrol, topographic map surveying by compared the original data from database with the surveying data later. This method is of high efficiency and accuracy, and it is used to discover automatically features change before Beijing topographic map database updating on scale of 1∶500.
