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 reusable geographic space information processing rapid modeling method. through a main technical scheme, aimed at geospatial information processing, various existing processing capacities can be widely gathered together, and a function maximum union under different platform environments is formed. Except for completely integrating the existing GP function of the ArcGIS, Python operator functions developed by other parties based on a GP model, operator functions developed by each special application in a customized manner according to requirements, and a large number of historical executable program functions are integrated into the model. Through a secondary technical scheme, the reusable effect of the model is maximized, and through simple secondary development and calling, the model formed by the main technical scheme can be rapidly accessed to various application environments, so that the application effect and the application range of the modelare greatly improved, and the rapid reuse difficulty of the model is reduced.

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 ...
