This paper describes the software module of the geographic information system, developed in the framework of research on methods for intelligent detection of anomalies for deep exploration of deposits. The module is based on the use of a mathematical model for determining the distribution field of a chemical element at a given depth given by the Fredholm integral equation with a Poisson kernel. The software module contains the implementation of algorithms for solving the indicated inverse problem for predictive calculations of the concentration of chemical elements based on measurement data on the day surface, as well as a number of auxiliary capabilities. The algorithm is implemented using the M. Lavrentiev regularization method and the Landweber iteration method. The results of predictive calculations are displayed on the map of the QGIS geoinformation system. The paper describes the structure of the software module and the process of its development, as well as the algorithm of QGIS user actions for interacting with the functions of the module. Implemented module is able to import the initial data obtained as a result of field and laboratory research into the databaseautomatically. The geographic information system database contains data on 29 chemical elements at 3920 points of material sampling in the Novo-Khairuzovsky area of southern Altai, located on the territory of Kazakhstan. The approbation of the mathematical model was carried out by comparing the calculated data with empirical data for gold. On the basis of the comparative analysis, it was concluded that the mathematical model makes it possible to recover the distribution field of chemical elements at a given depth of occurrence with an acceptable accuracy.
