The intelligent loading is a technology which is widely used in GIS Software. The paper designed a method which is based on the users' preference that is extracted and analysed from users' historical operating records. A matrix is used for describing the relation between code modules and users' behavior. Two vectors are used to formalize the users' behavior in the dimension of code modules. The two...
Different algorithms have been raised for viewshed analysis and measures were taken to get the compromise between performance and accuracy. The most accurate and standard algorithm is still the basic interpolation method, though its time cost is high. However, the development of Graphic Processing Unit (GPU) enables us to acquire high performance with normal PC, especially when the Compute Unified...
In wireless sensor networks, we usually need to detect interesting events based on the information gathered from multiple sensors. One useful detection is to test whether or not the average sensory value within an area is larger than a given threshold. Such type of query is called geo-range query. It should report the geographic centers where the average value of nearby sensors is greater than a certain...
