Processing method capable of rapidly rendering vector data, and system and electronic equipment

Abstract

The invention relates to a processing method capable of rapidly rendering vector data, and a system and electronic equipment. The method comprises the steps of configuring rendering colors and the position of a to-be-processed file; calling a geographic data format operation library GDAL to read source data information of a vector file generated by the to-be-processed file; calling a rendering class in the PyQGIS core library to execute rendering operation; and generating an SLD file and exporting the SLD file. According to the method, a vector rendering tool is optimized, a non-rendering vector function is removed, the overall program size is optimized, the memory occupation amount is dynamically adjusted, the problem that a large amount of memory of a computer is occupied when an existing rendering vector tool is started is solved, memory occupation is avoided, operation is easy and convenient, and efficiency is higher. Phenomena such as program false death and program crash are greatly reduced, and the problem that an existing rendering vector tool is unstable in performance is solved. According to the method, the independent software package is constructed through the Python language, the program is executed on the computer, college operation is achieved for simple rendering operation, and the GeoServer publishing requirement is rapidly met.

Description

technical field [0001] The invention relates to the technical field of data rendering, in particular to a processing method, system and electronic equipment capable of quickly rendering vector data. Background technique [0002] In the past 10 years, geographic information system technology (GIS technology) has developed rapidly, its functions have been continuously improved, and its wide application fields have increasingly shown. Among them, vector layer information is more widely used. At present, vector layers have penetrated into all aspects of society, such as agriculture, forestry, water conservancy, land, resources and environment, etc. Its specific applications include natural resource management, agricultural, industrial and commercial layout, political and economic analysis, urban land planning, engineering design management, science, education, culture and sports, national defense technology, financial transportation, public facilities and other fields.
