The paper describes the technology of Internet mapping of the ecological and magnetic state of soils on the example of the soil cover of the town of Chusovoi in Perm Region. The ecological and magnetic state of soils reflects the results of the long-term impact of industry and transport on the urban ecosystem, and the presentation of such data in the form of maps is generally accepted in ecological soil science. However, there is a problem of availability of spatial data characterizing soil pollution, caused, on the one hand, by the placement of materials in specialized literature and reports, and, on the other hand, by digital inequality due to the specificity of geographic information. In this regard, today the process of integration of geoinformation technologies and web technologies is actively taking place. The purpose of the research is to develop the technology for creating a typical web map of the ecological and magnetic state of soils in an urbanized area. The creation of a web map of the ecological and magnetic state of soils was carried out according to the standard stages of soil mapping: preparatory, field, and final cameral. Maps of magnetic susceptibility and content of heavy metals in soils were made using the ordinary kriging. Web application development is implemented using the qgis2web module and the Brackets code editor. The web application is hosted on the GitHub Pages platform. The results of the work represent a combination of geostatistics and visualization methods based on Internet mapping technologies, which makes it possible to present a whole set of geoecological maps dedicated to the ecological and magnetic state of soils in the form of a website. The presented geotechnology greatly simplifies the development of a soil-ecological web GIS application – the work is mainly carried out in a GIS environment and therefore does not require advanced competencies of a soil-cartographer in web programming.
