Geoportal for highways as a basic element of spatial data infrastructure

Abstract

This article is devoted to the development of geographic information systems, WEB-mapping and information integration into the spatial data infrastructure (SDI). The analysis of the history of the creation of spatial data infrastructure in the world community and in Russia is carried out, the specifics of the development of Web-GIS and SDI are revealed. As part of the study, the analysis of the world experience of using the Web-GIS of highways, as well as the current state of applied geoinformation systems in Russia was carried out. The key issue considered in the article is the development of the architecture of a Web GIS (geoportal) of highways for the purposes of accounting, analysis and systematization of spatial data. The main features of the formation of systems for recording data on highways are determined, the main tasks solved by these systems are given. The automobile road is a complex and lengthy object, which should become the spatial basis for the development of spatial data infrastructure in Russia. A block diagram of the main modules of the geoportal has been developed and proposed. The main functionalities implemented at each stage of the Web GIS operation are highlighted. As a result of the implementation of the proposed architecture of the geoportal, a system of analysis, systematization and management of spatial data of a road enterprise was introduced. The use of a geoportal significantly affects the optimization of the performance of various works on highways. Also, the result of the work (Web-GIS) can be implemented as a system for analysis, accounting and systematization of data on other extended linear objects (power lines, gas pipelines, water pipelines, etc.). A user interface of a geoportal, a structure for storing spatial data, modules for transforming coordinates and information, blocks for loading, analyzing and unloading data have been developed. The proposed architecture is versatile and easy to use, which is a clear advantage over the analog systems described in the study. Further study of the research topic opens up prospects for the rapid development of integrated geoinformation software tools on the Internet and a deeper understanding of the need to develop spatial data infrastructure.
