Abstract:

The article deals with the technology of creating a digital map of agricultural lands in QGIS in order to form an information base on their state in individual farms. As a result of the conducted research, the authors identified the main stages of creating a digital map, defined key tasks at the stage of spatial reference of raster images and proposed ways to solve them. We developed an algorithm for creating an attribute table using the Python programming language, which enables avoiding errors in the process of filling in the semantic part of the generated information base. The main tools for digitizing raster images are highlighted, and in order to identify mistakes in the process of forming its graphical part, a topological editing module is to be used. The obtained research results can be helpful for the executive authorities of the Russian Federation subjects, local self-government bodies to make decisions in the field of land and property management of a separate entity.
