A method for producing and publishing color topographic maps

Abstract

The invention discloses a method for producing and publishing color topographic maps. Based on the integration and support of relevant geographic information technologies, the invention proposes the storage management of geospatial network resources, digital elevation data processing, batch geospatial data rendering, and standard geospatial network resource service publishing. , standard geospatial network resource caching and other sub-processes, through the related processing process, realize the rapid production of topographic map data in grades and blocks, and provide a standard online topographic map publishing and access method. The present invention is mainly used to integrate geospatial data service resources, design relevant data processing procedures in combination with data features such as digital orthophoto, digital elevation, vector maps, generate clear and accurate topographic map data and services, and improve topographic data production and access efficiency .

Description

technical field [0001] The invention belongs to the technical field of geographic information, and mainly relates to a method for producing and distributing color topographic maps. Background technique [0002] In today's society with the rapid development of the Internet industry and information technology, geographic information technology-related industries have also developed rapidly, and various network map services have gradually become an important support for geographic information technology and big data platform technology. The network map service based on Internet resources is an important part of the public basic geographic information platform, and the basic geographic information carried is rich and diverse, which is convenient for people to recognize geographic space more intuitively. Topographic map data, as an important part of geographic information network map services, is a multi-dimensional geographic information network service released after the organi...

Problems solved by technology

However, today there are still many problems in terms of topographic map data sources, map accuracy, data quality, and service efficiency: network topographic map services based on geographic information transmission and expression of spatial entities have different forms in different industries and fields. Time semantics is seriously lacking, the expression object is incomplete, the scale is inaccurate, the carrying file forms are various, and the production system is huge and complex. At the same time, high-precision network topographic map service production and remote sensing technology, digital image processing technology, big data Parallel processing technology is closely related, and also requires the support and cooperation of different industries such as surveying and mapping, urban construction, aerospace, etc. Therefore, the early single topographic map data production method can no longer meet the existing comprehensive needs, and an efficient, accurate and convenient topographic map service is proposed It is very important to change the mode
