2015/11/20
Three Dimensional City Model (3DCM) research becomes a hot area in GIS field in recent years. The 3DCM research also has great significance in traffic, land, mine, surveying and mapping, and other fie...
AUTOMATIC MATCHING OF TERRESTRIAL SCAN DATA AS A BASIS FOR THE GENERATION OF DETAILED 3D CITY MODELS
LIDAR Laser scanning Fusion Matching
2015/6/1
The request for three-dimensional digital city models is increasing and also the need to have more precise and realistic
models. In the past, 3D models have been relatively simple. The models were de...
A framework for generalization of city models based on CityGML and X3D
CityGML X3D Generalization CityTree Visualization Aggregation
2016/4/12
In this paper, a novel framework for generalization of 3D city models based on CityGML and X3D is proposed. In the proposed framework, the CityGML files are first parsed into a Java environment to acq...
However, the semantic attribution within existing models is either poor or non-existent. In this work, we describe a novel and robust approach for the combination and enrichment of existing city model...
