ABSTRACT

A new concept of multi-source views (MSV) topographic data was applied for fusing top-view light detection and ranging (LiDAR) data with side-view SfM data as input for 2D model schematics. Unlike the top-view LiDAR topographic data, the new concept of multi-source views (MSV) topographic data maintains all information of top-view and side-view point cloud data, which now can be translated for creating the novel raster-based MSV topographic data. Merging multi-source views (MSV) topographic data mainly focuses on top-view LiDAR and side-view SfM data sources. By merging top-view LiDAR data and side-view SfM data, one could reduce some missing key features and create the novel Multi-Source Views Digital Elevation Model (MSV-DEM) to be used as topographic input data for complex 2D model schematisation. For the new MSV-DEM, errors in data processing can also accumulate but these new MSV data are better representing specific urban features of complex cities.
