Embodiment Construction
[0042] Preferred embodiments of the invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the invention, and are not intended to limit the protection scope of the invention.
[0043] It should be noted that, in the description of the invention, terms such as "upper", "lower", "left", "right", "inner", "outer" and other indicated directions or positional relationships are based on the terms shown in the accompanying drawings. Orientation or positional relationship, which is only for convenience of description, and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation on the invention.
[0044] In addition, it should be noted that, in the description of the invention, unless otherwise clearly stipulated an...

The invention provides a despecialized multi-source heterogeneous space-time geographic data integration system. The system comprises a basic geographic database module for providing geographic information, the city construction database module used for providing related city information for city construction management; the functional module used for independently realizing different functions; the data display module used for displaying data; the data service management module used for data configuration, the database processor used for processing relevant geographic database information andurban construction database information, the centralized processor used for processing the data information in a centralized mode to achieve corresponding functions, and the ArcGIS interface used forvisualizing a data model. A geographic information system technology, a database technology and a network technology are used as support to solve the problem that construction standards of departments and professional data are not uniform in the use process of geographic information resources, and interconnection and intercommunication and distributed online services of the geographic informationresources are achieved.
Description
technical field [0001] The invention relates to the field of data integration, in particular to a system and method for integrating de-specialized multi-source heterogeneous spatio-temporal geographic data. Background technique [0002] Geospatial data is different from general transaction management data. Due to the different understanding of spatial phenomena, the definition, expression, and storage methods of spatial objects are also different, which brings great inconvenience to geospatial data integration and solves multi-format data. Exchange has always been an important problem to be solved in the development of GIS application system in recent years. Currently, there are roughly three ways to achieve data integration. [0003] 1. External data exchange mode [0004] External data exchange refers to directly reading and writing the internal format and external format of other software or converting it to a certain standard format. It is an indirect data exchange fo...
