The data collection and updating are all related to editing module in GIS, whether or not the editing module is good determine the system effect and the feeling of the user even the users' judgments. This passage mainly talks about how to describe the geo-entities via geometry model and how the geometry model and the geo-entities model cooperate with each other.
For the limited monitor capacity and high cost of the "Compass" satellite navigation and positioning system, a virtual managed user computer system is proposed and designed in this thesis. The operating environment of the virtual managed user computer system - Compass monitoring and management network is introduced. Also, the differences between Compass and other systems are compared. The...
Nowdays, most people have embedded GIS devices, such as navigator, handset map and so on. But when developing embedded GIS software, programmers have to write different codes according to different embedded software and hardware. This paper explains the design and realization of Embedded GIS Graphic Mid-ware( CG-GDI). The Embedded GIS based on CG-GDI can be easily transplanted to other embedded software...
This paper analyzes the characteristics of the embedded GIS and the LBS. In addition, the paper presents how to solve the key technology in the embedded GIS, such as interactive map matching, keeping high time-effectiveness and using different electronic map modes.
Motivated by the principles of artificial neural networks in artificial intelligence, this paper presents the concept of mathematical templates and method for the construction of the mathematical model (called model for short) through these templates nesting and recursive calls. Based on this idea, a new strategy for the construction and its application of the model in embedded GIS are advanced, first,...
The structure, dynamics as well as IR spectrum of water molecule in tetra-fluoroborate (BF4-) solvation shell at room temperatures are studied by computer simulation. Various BF4- anion and water mixture with varying concentrations were simulated to understand the interactions and dynamics. In both liquids, water molecules tend to be isolated from each other in mixtures with more ions than water...
