This method gives accuracy results of ±2 mm in altimetry and better than ±5 mm in planimetry, but it requires a lot of expenditures and a long time of execution and more staff. Nowadays, the constellation of the GNSS satellite positioning system and the improvements to electronic tachymeters can provide solutions to gaps in auscultation using conventional measurements. However, these methods also present their weaknesses, resulting by this way from their uses under the high voltage lines. The study of the influence of electromagnetic waves on high-voltage lines on topographic devices allows observations made with a GNSS receiver to be made from an electronic station or total station or with the aid of optical-mechanical theodolite to analyse and interpret the quality of the data obtained on the ground in the Maria Gléta zones in the municipality of Abomey-Calavi and Araromi in the municipality of Sakété. This makes it possible to present the effects of high voltage cables on these measurements and the determinations made in topometry. Very important on measurements at the GNSS receiver and at the total station, the actions of the electromagnetic waves evolve with the variation of the temperature.</p></abstract><trans-abstract xml:lang="ru"><p>Точные топографические работы выполняются посредством таких классических инструментов, как высокоточный уровень, угломер и дальномер. С их помощью можно получить результаты с точностью до ±2 мм при измерении высот (альтиметрии) и до ±5 при измерении площадей (планиметрии). Но этот способ является затратным с точки зрения финансов, времени и количества персонала. Сегодня система спутниковой навигации ГНСС совместно с усовершенствованными моделями электронных тахиметров может решить проблему устранения пробелов при измерении территорий стандартными методами. Тем не менее и данные методы не являются совершенными, имея сбои в работе при использовании под высоковольтными сетями. Изучение влияния электромагнитных волн высоковольтных линий на топографические устройства позволяет проводить наблюдения при помощи спутникового приемника (GNSS-приемник) и электростанции, общей станции (total station) или при помощи оптико-механического теодолита с целью интерпретации и анализа качества данных, полученных на земле в зонах Мария Глета (Maria Gléta) муниципалитета Абомей-Калави (Abomey-Calavi) и Арароми (Araromi) муниципалитета Сакете (Sakété). В результате можно определить степень влияния высоковольтных кабелей на качество выполняемых в топометрии измерений. При проведении измерений GNSS-приемником и общей станцией (total station) важно учитывать, что активность электромагнитных волн зависит от изменения температур.</p></trans-abstract><kwd-group xml:lang="en"><kwd>GNSS receiver</kwd><kwd>electromagnetic waves</kwd><kwd>satellite positioning</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>GNSS-приемник</kwd><kwd>электромагнитные волны</kwd><kwd>спутниковая навигация</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Degbegnon L.
