Method for unified data modeling in informatization surveying and mapping production equipment integration process

Abstract

The invention discloses a method for unified data modeling in the informatization surveying and mapping production equipment integration process. The method comprises the steps of defining data description, wherein data attributes and space features are included; defining a data cube structure, wherein an organization structure and format specifications forming a data cube unit are included; explaining the content of the data description and the data cube structure, outputting a data model file (xsd format), constructing data types and completing model building; extracting data cubes and features of the data types, recombining the data cubes, rebuilding the features, achieving information conversion between different data types, and completing model conversion. According to the method, various data resources are modeled in different environments in the informatization surveying and mapping production equipment integration process through a unified data modeling model, data conversion between different environments is achieved, and data are processed more reasonably, directly, rapidly and clearly.

Description

technical field [0001] The invention relates to the field of information processing, in particular to a method for unified data modeling in the integration process of information-based surveying and mapping production equipment. Background technique [0002] At present, my country's surveying and mapping methods and application of results are gradually entering the information age from the digital age. Photogrammetry technology has an unprecedented level of automation and intelligence, geographic information element data production software is in full bloom, information-based surveying and mapping production management models show a new scene, information-based surveying and mapping key support technologies have initially formed a system, and hardware equipment is developing towards cluster computers and cloud computing platforms. Data resources have initially realized network integration and sharing, and the surveying and mapping function has been transformed and upgraded f...

AI Technical Summary

Problems solved by technology

During the integration process of information-based surveying and mapping production equipment, production software in different environments has different standards for data definition, and there is a lack of a unified standardized data model to support the software, resulting in data connection, processing interoperability and system integration among different production software. On the one hand, there are differences in data semantic description, which brings a lot of development workload, and the efficiency of data management and the degree of sharing and utilization are not high
