Предложен вычислительный алгоритм для определения взаимосвязей ЭУ разных туров агрохимического обследования земель, основанный на применении алгоритма Уайлера – Атертона, который позволяет находить области пересечения границ элементарных участков и выполнять расчет процентного вхождения площадей ЭУ предыдущего тура в ЭУ текущего тура, что делает возможным установление между ними связей типа «родитель – потомок». Разработанное на основе предложенного алгоритма программное обеспечение реализовано с использованием современных веб-технологий (PHP, Drupal, MySQL, Bootstrap, Leaflet), что обеспечивает пакетную обработку больших массивов геоданных, визуализацию границ ЭУ на интерактивной карте и создание удаленного доступа к получаемым результатам. Апробация метода на материалах предполагаемых 15-го и 16-го туров агрохимического обследования показала его эффективность для выявления пространственных соответствий между ЭУ. Разработанные вычислительный алгоритм и программное обеспечение открывают новые возможности для ведения истории полей, расчета доз удобрений и оценки их эффективности, а также для решения инновационных задач точного земледелия и комплексной оценки состояния биосферы.</p></abstract><trans-abstract xml:lang="en"><p>The study considers the problem of determining geographical relationships between agricultural management zones (MZs) across different rounds of agrochemical surveys of agricultural lands in the Republic of Belarus. A computational algorithm is proposed for identifying relationships between MZs from successive survey rounds, based on the application of the Weiler – Atherton polygon clipping algorithm. The algorithm enables the detection of intersection areas between MZ boundaries and the calculation of the percentage of overlap between MZs of the previous and current survey rounds, thereby allowing the establishment of hierarchical “parent – child” relationships among them. Software developed on the basis of the proposed algorithm was implemented using modern web technologies (PHP, Drupal, MySQL, Bootstrap, Leaflet). The system provides batch processing of large volumes of geospatial data, interactive visualization of MZ boundaries on digital maps, and remote access to analytical results. Experimental validation using geodata from the supposed 15th and 16th agrochemical survey rounds demonstrated the effectiveness of the proposed approach in identifying spatial correspondences between MZs. The developed computational algorithm and software offer new opportunities for the field history maintaining, optimization of fertilizer application rates, and evaluation of their agronomic efficiency, as well as for addressing advanced challenges in the precision agriculture and comprehensive biosphere assessment.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>элементарный участок</kwd><kwd>алгоритмы пересечения многоугольников</kwd><kwd>алгоритм Уайлера – Атертона</kwd><kwd>анализ геоданных</kwd><kwd>история поля</kwd><kwd>геоифнормационная система</kwd><kwd>ГИС</kwd><kwd>агрохимическое обследование</kwd><kwd>мониторинг окружающей среды</kwd></kwd-group><kwd-group xml:lang="en"><kwd>agricultural management zone</kwd><kwd>polygon intersection algorithms</kwd><kwd>Weiler – Atherton algorithm</kwd><kwd>geospatial data analysis</kwd><kwd>field management history</kwd><kwd>geo-information system</kwd><kwd>GIS</kwd><kwd>agrochemical survey</kwd><kwd>environmental monitoring</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Основные мероприятия по повышению плодородия почв сельскохозяйственных земель Республики Беларусь на 2021–2025 годы / В.
