Аннотация: The city is a complex system in which all components of the ecosystem interact with each other. In the course of the constant collection of information about the ecological situation, significant amounts of data are accumulated, the combination of which in a single information space provides new opportunities for obtaining new knowledge about the study area. The paper presents a study of the ecological component of the urban environment quality on the example of Krasnoyarsk city using open spatial data. Since one of the main factors for the assessment is the natural and ecological situation in the city, the following quality indicators were selected: the nature of thermal anomalies, air and land surface temperature, relief, number of storeys of residential and industrial buildings, concentration of suspended particles. The data on the land surface temperature were prepared using the Landsat-8 satellite data from 2013 to 2020, cloudless scenes were selected during the snowless period, which amounts to 30 scenes per city territory. The Open Street Map database was used to determine the number of storeys and types of all city structures. To achieve the goals, the authors selected the necessary vector layers for analyzing the urban environment, carried out a search and download of data on the air temperature and the land surface temperature, organized a single information space for geoinformation analysis across the Krasnoyarsk city. As a result of the geoinformation analysis, the search for relationships between objects was carried out, a comparison of data on one indicator from different monitoring sources was made. A vector polygonal layer has been created from small segments on the territory of the city that are more homogeneous in terms of buildings and relief features to search for relationships. Sets of layers where seasonal thermal urban anomalies are displayed have been created, the ratio of stable elevated temperatures to local climatic zones has been found, and existing sources have been evaluated regarding assessment of atmospheric air in relation to stable heat islands. © 2021 Copyright for this paper by its authors.
