Novel geographic computing mode

Abstract

The invention relates to a novel geographic computing mode. The computing mode comprises an intelligent document system, a geographic model computing control system and a background interpretation system. The intelligent document system adopts a natural language to describe a calculation task, an evaluation model and a calculation process through a WORD document; the geographic model calculation control system acquires a task name and drives the background interpretation service system; and the background interpretation service system is used for interpreting and executing the WORD document inthe intelligent document system and outputting an execution result. In a traditional geographic computing mode, a technical document only guides a technician to operate, and a computing result completely depends on the level of the technician, but under the novel geographic computing mode, the technical document is intelligentized through the DAS technology, the content of the intelligentized technical document is directly driven by the system, the processing flow of each evaluation index is executed, the evaluation process is automatically recorded, and the flexibility is very high.

Description

technical field [0001] The invention relates to a new geographic calculation mode, and relates to fields related to geographic calculation, such as land space planning, environmental assessment and the like. Background technique [0002] As the basis for the compilation of national land and space planning, the double evaluation of land and space planning (hereinafter referred to as double evaluation) needs to involve a large amount of data processing and calculation, and the work is complex and arduous. First, the scope of implementation is wide: According to the unified deployment of the Space Planning Bureau of the Ministry of Natural Resources, the double evaluation work needs to be carried out at the national, provincial, city and county levels. Due to time constraints, urgent tasks, high requirements, especially the technical strength at the city and county levels, it is difficult and challenging to fully implement and complete the dual evaluation work with quality and ...

Problems solved by technology

Third, the data processing is difficult: the double evaluation work involves a large amount of spatial data processing. The technical guide includes 7 individual evaluations, 5 integrated evaluations and 5 comprehensive analysis, and also includes 3 optional evaluations. For these evaluations or analyzes , all need to go through multiple spatial data processing steps, ranging from a few to dozens, and the entire double evaluation work requires a total of nearly 400 processing steps

Although visual modeling does not require programming, the scale of the built model is limited, and it is difficult to maintain, debug and use the model

The script development mode requires a certain foundation of software development programming, but it faces the problem of system code maintenance to deal with the flexibility of evaluation work

However, the system development mode needs to be developed independently, which has high requirements for technical personnel, and the developed system has poor flexibility, which cannot meet the flexibility requirements of geographic computing.

At the same time, these four calculation modes all have the problem that the evaluation process is not automatically recorded, and the evaluation results are difficult to check
