A SYSTEM FOR GENERATING URBAN SPATIAL INFORMATION USING BUILDING DATA SELECTED ACCORDING TO LEVEL INFORMATION OF URBAN SPATIAL INFORMATION MODEL

摘要

PURPOSE: a kind of system is provided to support decision and improved intuition by providing accurate and realistic virtual environment according to grade information city space information model using the selection of building data for generating city space information. ;CONSTITUTION: mistake removes the coordinate value that unit (311) remove the exploration area airborne laser scan data of error information, according to the point of surrounding. Filter unit (312) filter scan data are identical into road data and the first building data to classify. Data extraction device (313) extracts road data and the first building data. Original drawing data extraction unit extracts the database that original drawing data includes 3D coordinate value buildings. Data conversion unit executes the original drawing data of coordinate conversion. ;The 2013 of copyright KIPO submissions;The unit of [Reference numerals] (310) data classification; (311) error removal unit; (312) coarse filter unit; (313) data extraction device
