Optical measurement technologies refer to laser scanning and photogrammetry which output point cloud and raster imagery. CAD-based method is not sufficient to represent such data in terms of accuracy and richness. The essence is drawing method lags behind  measuring technologies. The project addresses this problem by integrating BIM-GIS-CAD with reference to various levels of surveying hierachy.
