An Integrated 3D Cadastre-Malaysia as an Example
3D Cadastre Integration Spatial Objects DBMS
2015/12/11
In Malaysia, the cadastre system is controlled by two main agencies, namely, Department of Surveying and Mapping Malaysia (DSMM) and Land Offices (L.O). The DSMM is responsible for the cadastral spati...
Monoplotting - a Semi-Automated Approach for 3D Reconstruction from Single Satellite Image
Modelling Reconstruction Triangulation Visualization Rendering Semi-automation
2015/12/9
Once the predicted base and shadow positions match their positions in the image by observation, the height of the object is determined. As a consequence, the 3D object is reconstructed simultaneously....
