Embodiment Construction

[0017] The technical solution adopted in the present invention is: a batch processing system for geographical and national conditions census data, characterized in that it includes batch projection, batch cutting, batch merging, batch conversion, batch geometric operation, batch fusion, batch generation of map formats, and MDB files Designate layer operations, extract geographical conditions data, calculate building density, organize sample data, organize basic statistical analysis data, add administrative division fields, and create the above modules for DOM metadata.

[0018] Preferably, the batch projection includes a single MDB file assignment projection; the single MDB file clears projection information, and the clear projection is used to remove the projection information of the layer in the MDB file, and the layer projection becomes Unknown after removal; the SHP file batch Assign projection; MDB file batch projection; GDB file batch projection; file batch projection tra...

Abstract

The invention discloses a geographical national condition census data batch-processing system which comprises batch development, batch cutting, batch merging, batch conversion, geometrical batch operation, batch fusion, batch graph breadth generation, MDB file specified coverage operation, geographical national condition data extraction, building density calculation, sample data organization, basic statistical analysis data organization, administrative division field adding and DOM data making modules. The geographical national condition census data batch-processing system is simple in structure, and the functions of geographical national condition data extraction, building density calculation and sample data organization are developed specially for geographical national condition census.Conversion from basic geographic information data to geographical national condition census data is completed through geographical national condition data extraction. The building density calculationmodule is used for calculating the proportion of building floor area in the total housing estate area. The sample data organization module is used for completing collection of remote-sensing imagery interpretation sample data, including field operation inspecting information and remote-sensing image cutting, cut remote-sensing image four-axis coordinate reading and other functions, and the geographical national condition census data batch-processing system aims to generate sheets in the forms required by remote-sensing imagery interpretation sample databases.

Description

technical field [0001] The invention relates to the technical field of big data processing, in particular to a batch processing system for geographical and national conditions census data. Background technique [0002] Geography and national conditions are to analyze, study and describe national conditions from the perspective of geography, with the spatial changes of natural, biological and human phenomena on the earth's surface and their interrelationships and characteristics as the basic content, and analyze the various conditions and factors that constitute the material basis of the country. Make macroscopic, holistic and comprehensive surveys, analyzes and descriptions, and form spatial and visualized information on national conditions. The census of geographic and national conditions is a major survey of national conditions and national strength. Finding out the geography and national conditions is of great significance for understanding national conditions, grasping n...
