This paper touches upon the experience of research and development of hardware and software for air pollution monitoring of industrial cities, carried out at the Institute of Computational Modeling of the Siberian Branch of the Russian Academy of Sciences. Functional possibilities, architectural features, and user interface of the distributed web geographic information system of ecological monitoring of the city of Krasnoyarsk, which is being developed in service-oriented architecture, are discussed. Data are collected from automated posts for observing the state of atmospheric air and services of aggregation and representation of information in the form of interactive graphs and thematic maps in the web interface. An original device is developed for measuring the pollution level of the atmosphere with fine dust (PM2.5), the data from which is fed in real time to the system via a cellular network. A system is formed for integral assessment of the pollution level of the atmosphere based on Air Quality Index (AQI) calculations.
Formation and effective use of geospatial data is today one of the most pressing problems facing the scientific community and public authorities. Are posed the task of technological and organizational support geographically distributed systems for collecting, processing, storing and providing spatial data and metadata. These systems must provide its users with remote access to digital geographic information, provide them with information interaction. Consider the stages and features of the creation of the state information system, the 'Bank of spatial data' for interagency cooperation and integration projects of Krasnoyarsk region along line cataloging, storage, analytical processing and publishing of geospatial data. Considerable attention is given to web services, software interfaces and generally accepted standards. In developing the software many different software libraries and components were used. Web mapping user interface was created using a number of open source libraries. To create a server-side web application author used GIS platforms MapGuide Open Source and Minnesota MapServer. GeoWebCache was another essential component of distributed web mapping environmental monitoring applications.
ПРОГРАММНО-ТЕХНОЛОГИЧЕСКОЕ ОБЕСПЕЧЕНИЕ ГЕОИНФОРМАЦИОННОЙ СИСТЕМЫ БАССЕЙНА Р. ЕНИСЕЙ Резюме. В работе рассматриваются вопросы формирования проблемно-ориентированной геоинформационной системы бассейна р. Енисей на основе междисциплинарных научных исследований. Создание системы, в которой будут собраны и систематизированы сведения о его речной сети, обеспечит возможность проведения анализа и моделирования гидрологических процессов, различных природных и природно-техногенных явлений, качественной и количественной оценки водных ресурсов, экологического состояния. Методической основой разработки является формируемая региональная система показателей устойчивого природопользования. Разработка создается в сервис-ориентированной парадигме на основе геопортальных технологий, средств интерактивной веб-картографии, системы распределенного хранения и обработки данных. Основное внимание в настоящей статье уделяется проблемам формирования программно-технологического обеспечения, особенностям реализации программных компонент веб-ГИС, вопросам эффективной обработки и представления геопространственных данных. Ключевые слова: геоинформационная система, бассейн р. Енисей, геопортал, геопространственные данные, веб-картография, веб-приложение, картографический сервис, тайловая подложка, веб-шаблон.
