UAV Aeromagnetic Survey

UAV Aeromagnetic Surveys utilize advanced drone technology to capture high-resolution magnetic field data over specified areas, providing critical insights for geological and mineral exploration. By employing Unmanned Aerial Vehicles (UAVs) equipped with sensitive magnetometers, we can efficiently map subsurface geological features, detect anomalies, and identify potential resource deposits.

Our UAV Aeromagnetic Surveys offer numerous advantages, including rapid data collection over large and difficult terrains, reduced costs compared to traditional methods, and minimal environmental impact. The high precision of the magnetic measurements allows for detailed analysis and interpretation, helping clients make informed decisions in mining, archaeology, and environmental studies. Our experienced team conducts thorough pre-survey planning, ensuring optimal flight paths and data acquisition parameters. After the survey, we process and analyze the magnetic data using advanced software, delivering comprehensive reports that highlight significant geological features and anomalies.

Our drones are fitted with LIDAR as well for topographically challenging areas pre-empting safe aeromagnetic surveys.

Aeromagnetic Surveys find its applications in mineral ore exploration & archaeological research, primarily because of the presence of ferromagnetic minerals in ores resulting in magnetic anomalies.

Applications

Deposits survey
Using UAV for precise magnetic field data acquisition
Agriculture
High resolution aerial imageries help assess crop health, soil conditions and drainage system of the farmlands and thus facilitating effective farming. Aerial surveys provide accurate field size which is key to efficient cost management by correctly assessing the cost of seeds, fertilizers, pesticides & fuels and also avoids inaccuracies in yield estimations. The 3D models from the aerial surveys provide accurate crop volume measurements and help insurance assess damage assessments in case of eventuality.
Urban development and land planning
Constructing intricate models of cities and cultural heritage sites, spotting cadastre violations and real land use borders, and creating structures and urban amenities in three dimensions. High spatial resolution allow keeping effective accounting of small objects such as advertising structures.
Geodesy
Geoscan technologies allow to solve any mapping issues within the shortest possible time and with the minimum labor costs. Create detailed maps and accurate 3D models with the help of out UAVs
Construction
Tracking operational changes and keeping an eye on the construction process, progress and scope of performed earth works, constructing three-dimensional panoramas of built-in real estate items, current and precise information about the geometrical features of structures, construction sites, and associated infrastructure. The UAV surveys enables quality control of the performed works and the geometrical parameters of the erected structures. The results of the engineering – geodetic surveys performed prior to construction are subject to the relevant data of the area provided by the UAV survey products.
Mining
Accurate and current geometry information about a mine, quarry, or section's surface. Control over the extent of excavation, production volume calculations, overburden removal volume accounting, loss calculations, and side and dump steady state monitoring. Manage property and equipment.
Public road system
Monitoring of road pavement condition, construction of longitudinal and cross profile. Examination of the railway bed, bridges and other facilities.
Oil and gas sector
Monitoring of the oil and gas infrastructure, ground surface subsidence, territory ecological state and reclamation activities. Resource management, inventory of existing objects and objects under construction.
Forestry management
Economical forest land monitoring, inventory of forest areas without lengthy detours for inaccessible areas, estimating heights of the trees wood reserves, locating places for drying and falling, and detecting breaches. Accurate spatial data enable development of thematic maps helping in placement of roads, trails and loading sites
Energy industry
Regular monitoring of energy infrastructure facilities (Power Transmission Lines, Power Stations, etc.) enables on time detection of defects of insulation and corrosion thus avoiding emergency situations. Products of UAV data processing viz. orthophotos, digital surface models and high resolution photos help in making topographic & thematic maps and define power tower locations with surrounding forestry or trees dangerous to the wires, reconstruction of wire positions and new PTLs and erecting the facilities with suitable approach roads.
