The combination of basic mapping data production of Sunway Technologies and SuperMap GIS makes basic mapping data into GIS applications, providing more straight forward support. In the intelligent mapping situation, building a mapping circle can provide intelligent geo-information solution.
Mapping industry is the basic for economic construction, defense construction and social development. With the development of time, mapping technologies also changed from artificial collection to the intelligent methods like satellite navigation, drone, internet or IoT, big data, etc.
The main features of intelligent mapping are: using new technologies like drones, oblique photogrammetry to acquire land surface model data; using oblique photogrammetry to acquire DLG data, automatic discrete modeling; 2D & 3D integration database setting and dynamic updating to improve the services of intelligent mapping, smart city.
In order to meet the requirements of intelligent mapping, fully use mapping data. In 2016, SuperMap and Sunway set joint development team, adding EPS data model in SuperMap SDX+, making data generated by EPS stored in SuperMap SDX+. After integrating the model, the GIS functions and 3D visualization have been embedded in SuperMap GIS.
The traditional mapping process is to set up database and then produce and process data, finally use data. The database created in EPS or SuperMap can be opened and managed by both of software, skipping the data exchange process. After transforming data into map, the map can be published by SuperMap.
EPS 3D mapping system is based on oblique photogrammetry data; using digital orthophoto image, surface model as basic, realizing data overlaying, multi-window, multi-view, 2D & 3D linkage displaying and mapping, the collection results can be shown in SuperMap.
The real estate data generated in EPS can be seamless shown in SuperMap. In 3D scenes, it can be extended into building directly, automatically generate 3D model. The attributes of the building can be shown directly.
In the data production and processing, the dynamic updating technology can realize update on 2D & 3D data, realizing the data downloading and uploading and automatic checking.
3D Pipeline Data Production and Application
The pipeline data collection, graphic editing, attribute editing, etc. are provided by EPS pipeline data production, which can generate 2D pipeline data. The pipeline data generated by EPS can be displayed in SuperMap, which supports displaying in symbol, also supports loading in 3D scene. The pipeline styles can be set, like where are connected, and burst analysis, etc., combining with city model, making a real city grid system.
No matter in traditional or intelligent mapping solutions, real estate data, 3D pipeline data. We can see that the advantages of Sunway technologies are database setting and production of mapping data. And the advantages of SuperMap are GIS application, making various mapping data into GIS application, providing solution support for decision makers.
In conclusion, the cooperation of SuperMap and Sunway will create mapping circle, providing GIS solutions for users.
