To establish the framework of
digital geological survey with new generation of information technology
and raise the current digital geological survey to a more intelligent
level, authors investigate the characteristics of procedures in digital
geological survey (e.g., data acquisition, data processing, data
communication, 3-D modeling, and information service) based on tools
such as cloud computing, cloud GIS, and Hadoop Ecosystem. It is the
author's opinion that the construction of intelligent space is the core
of intelligent geological survey (IGS). Intelligent space is a
composition of information space and physical space, as depicted in
Fig.1. It has ubiquitous computing ability of perception, analysis,
reasoning, communication, and self-adaptation in order to serve the user
intelligently. The information space consists of context awareness,
comprehensive analysis and modeling, knowledge discovery (data mining),
etc. On the other hand, the physical space is a new generation
technology portfolio of Internet, Internet of Things, communication
network, Cloud Computing, and big data solutions.
To build a working pattern for big data in an intelligently cognitive perception way, integration of cloud and in the cloud, ground-air-space, 2-D and 3-D, information space and physical space, geological survey procedure and GIS technology has been highlighted during the construction of basic software system platform. Particularly, it can support intelligent functions like knowledge service of current location, dynamic data acquisition, and fast modeling during field geological survey. To deal with key issues of resources sharing and interconnecting between information space and physical space, multiple technologies (e.g., Cloud Computing, Cloud GIS, Grid Computing, and Hadoop) are integrated, especially at resources layer and resources aggregation layer. Therefore, the working mode with intelligent perception services and ubiquitous service can be achieved in geological survey. Meanwhile, based on the HBase storage model and rules of ontology domain knowledge, the dynamic participle knowledge database can be created via machine learning mechanism. Hence, overall efficiency and accuracy of data discovery and mining can be improved.
Nowadays, intelligent mobile phone has powerful perception ability of location, attitude, motion, and environment information. First, it becomes a semantic electronic field record book for the digital geological survey system, which combines description of geological route, assisted recording of audio and video, perception of geology attitude, and profile of route. Second, it provides automatic perception service that covers from the physical coordinates to semantic geological location (including the geographical map and the geological position at the current location). This new generation geological survey system has been applied to the geological mapping in China since 2011.
