Abstract
The article presents the results of the development of an open geoinformation system of soil cover based on a medium-scale soil map. The scale of the map is 1:100 000. Coverage of the territory—Okhansky Urban District of the Perm Krai. The relevance of the work performed is caused by the growing demand for digital soil-cartographic information on a medium scale, which is characterized by representativeness in the conduct of a land cadastre, environmental impact assessment, obtaining information about the thickness of the fertile layer in civil, industrial and road construction, as well as in the development of adaptive landscape farming systems. The purpose of the research is to develop and test a method for integrating archival soil-cartographic materials with open web GIS solutions for a modern level of visualization and efficient use of soil maps (using the example of a medium-scale level within the boundaries of the Okhansky Urban District of the Perm Krai). For vectorization, the scanned map was defined in the coordinate system of the Pulkovo 1942/Gauss-Kruger zone 10 projection. As a result of vectorization, the total number of soil contours was 648. The source of attributive information is the soil outlines of land uses in the Okhansky District of the Perm Krai. The structure of the GIS project, in addition to the layer of soil contours, contains thematic layers characterizing the granulometric composition and quality classes of soils, calculated by the method of A.S. Fatyanov. The developed technological scheme for creating an open soil web GIS has two main blocks: the development of a GIS project and web design. Between them is the result of the functioning of the qgis2web module, which allows you to create a web map from a GIS project. Open access to GIS is organized at the web page [Web resource: https://chascshin.github.io/Ohansk-GIS (accessed 27.09.24)]. Using GitHub Pages to host a site with a web map significantly reduces the cost of the final geoinformation project. However, the main disadvantage of GitHub hosting is the limitations on the count and amount of data.
