Problems solved by technology

[0003] ①The technical defect of ArcGIS ModelBuilder is caused by the limitations of its GP processing tool. Its underlying technology implementation relies on Windows COM technology, which has strict specification restrictions on the realization of the model operator interface. Therefore, a complete technical system can be guaranteed for the closed platform, but for third-party model computing Insufficient sub-access support
[0004] ②The technical defect of GeoKettle is that its modeling method is developed from Kettle, and Kettle is a pure ETL modeling processing tool, which must execute the built model through its command line mode or GUI mode. Micro-quantity cohesion leads to separation from the operating environment provided by it, and the model cannot be embedded into other applications

Embodiment Construction

[0028] The present invention will be further described below in conjunction with accompanying drawing:

[0029] Such as figure 1 Shown:

[0030] ①Compared with this technical method, ArcGIS ModelBuilder technology can only use the built-in GP processing tool that meets its interface requirements to model, and cannot quickly integrate third-party processing tools and executable programs into the processing model as processing operators;

[0031] ② Compared with this technical method, the GeoKettle technology can only run the model in its host environment for data ETL, and cannot separate the core model and quickly integrate it into other application scenarios for secondary development and call.

[0032] The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above. Those skilled in the industry should understand that the present invention is not limited by the above-mentioned embodiments. What a...

Abstract

The invention discloses an automatic and reusable rapid modeling method for geospatial information processing. Through the main technical scheme, for geospatial information processing, various existing processing capabilities can be widely gathered together to form different platforms The largest combination of functions in the environment, in addition to the complete integration of the existing GP functions of ArcGIS, the Python operator functions developed by other parties based on the GP model, the operator functions developed by each topic application according to the needs, and the large amount of historical accumulation Executable program functions are all included in the model. Through the secondary technical scheme, the reusable effect of the model can be maximized. Through simple secondary development calls, the model formed by the main technical scheme can be quickly connected to various application environments, which greatly improves the application of the model. The effect and application range reduce the difficulty of rapid reuse of the model.

Description

technical field [0001] The invention relates to a rapid modeling technology method for geographic spatial information processing, in particular to an automatic and reusable rapid modeling method for geographic spatial information processing. Background technique [0002] For the rapid modeling technology method of geospatial information processing, there are two kinds of existing technologies closest to the present invention: one is the ModelBuilder modeling method in the commercial geographic information software represented by ArcGIS; the other is represented by GeoKettle Open source geospatial information ETL tool modeling method. [0003] ①The technical defect of ArcGIS ModelBuilder is caused by the limitations of its GP processing tools. Its underlying technology implementation relies on Windows COM technology, which has strict specification restrictions on the realization of the model operator interface. Therefore, a complete technical system can be guaranteed for the ...
