The city environmental element was extracted using Geographical Information System (GIS). The influence of the city environmental element was correlated with the formation of land values and analyzed ...
Cadastral topological structure change is the foundation for conducting change analysis, and updating data in Cadastral Information Systems (CIS), and it almost happens every day in many cities. In th...
The generalization operation should first make decision of object importance at geographic level, which relates not only to the geometric properties of independent object but also the other context ob...
College of Informatics, South China Agricultural University, 510642 Guangzhou, Guangdong, China E-government software structure was proposed according to the solutions refining from the development pr...
This work presents a new approach towards the construction and manipulation of 3D cells complexes, stored in the Augmented Quad-Edge (AQE) data structure. Each cell of a complex is constructed using...
In this paper, we propose a robust metric structure from motion (SfM) algorithm for an extended sequence with outliers and missing data. There are three main contributions in the proposed SfM algorit...
Handling time in geospatial information systems (GIS), the applicability of these valuable systems will increase, so, there hardly exist an application dealing with spatial information which can not b...
Re cently, a l as er sc anne r has be en r ec eivin g mor e att ention as a us e ful to ol for r e al-time 3D dat a acquisition, and various applic ations su ch as c ity mode ling, DTM gener ation an...
To efficiently store, retrieve and update the globalspatial data, a hierarchical and dynamic data model on a globalscale is urgently needed. The QTM (Quaternary Triangular Mesh) as a hierarchical qua...
A large number of strategies and implementations of Structure from Motion (SFM) have been developed; some are being included in photogrammetric software packages. However, finding specific parameters ...
