In order to cope with system complexity and dynamic environments, modern industries are investing in a variety of sensor networks and data acquisition systems to increase information visibility. Multi-sensor systems bring the proliferation of high-dimensional functional profiles that capture rich information on the evolving dynamics of natural and engineered processes. This provides an unprecedented...
Log management module plays an important role in the massive spatial database management system. Recently there are few three-dimensional spatial database management systems with pertinent log management sub-system, or the administrator can only use the log, which is attached by database system, to recover the data. To improve this issue, hierarchical structure of the log management module should...
Sorts of models in current geological hazard information management system and digital disaster reduction system (DDRS) in China still lack of enough basic data support. One key problem is how to realize integration and share of complex geological hazard heterogenous spatial information. Isomerous geological hazard data have four types: structural isomer, syntax isomer, system isomer and semantic...
