Problems solved by technology
The existing sensor network ontology has the following problems: the sensor network ontology is built in isolation with the sensor as the center or the observation data as the center, and does not give a complete definition and description of the relationship between the sensor, the observation process, and the observation data product. The data source is single, and the semantic description of the multi-source data information in the geospatial sensor network is not detailed enough, which cannot meet the complex needs of users for multi-source heterogeneous data, and cannot meet the requirements of intelligent search and decision-making services

The invention relates to the technical field of geographic space observation, in particular to a geographic space sensor network body construction method and device. The method comprises the following steps of: constructing a geographic space sensor network observation resource according to hardware physical information of a sensor, attribute information of an observation object, attribute information of an observation process, attribute information of observation data generated by the sensor in the observation process and attribute information of an observation product; configuring semantic description element metadata for the geographic space sensor network observation resource; expanding an inner type and an attribute of a to-be-expanded geographic space sensor network body according to the semantic description element metadata; and under an appointed application circumstance, obtaining the observation data and metadata of the observation data according to the expanded geographic space sensor network body, and carrying out living example type construction, interior associated construction and exterior associated construction on the expanded geographic space sensor network body. The method and device provided by the invention are rich in data sources and are capable of satisfying the requirements, for multi-source observation data, of the users.
Description
technical field [0001] The invention relates to the technical field of geospatial observation, in particular to a method and device for constructing a geospatial sensor network ontology. Background technique [0002] With the development of modern technology and the continuous maturity of the manufacturing industry, a large number of sensor devices are used in various aspects of human society, such as disasters, weather, agricultural production, etc., to help people obtain more that cannot be obtained due to human limitations. information. A large number of sensors constitute a sensor network, which can continuously provide periodic and multi-mode observations, providing a more powerful data basis for accurate analysis and decision-making. [0003] According to the different application fields and core concept definitions of sensor network ontology, the existing sensor network ontology is mainly divided into two categories: sensor-centered construction and observation data-...
