An important element of water resources management is monitoring. Evaluation of human impact, erosion processes and water logging, monitoring of waters quality require performance of time-consuming and expensive works.

UAVs provide unprecedented opportunities for remote mapping and spatio-temporal monitoring of the water bodies. Surveying with the desired frequency, you can observe development of a variety of hydrological processes and identify their consequences. The automated process of spatial data collection and processing ensures high accuracy of results. At the same time, our complexes significantly increase efficiency of the performed operations and reduce labor costs.

Regular monitoring

Simple and safe to handle, and at the same time being reliable, Geoscan UAVs enable you to obtain highly accurate spatial data that are not possible or very difficult to obtain by the use of other remote-sensing methods. Our surveying complexes will give you a possibility of aerial monitoring of water resources and the surrounding area. Regular water regime monitoring ensures the correct and timely decision-making and will help to use the resources more effectively. With access to the detailed images, you will be able to identify different changes in the water masses. Eutrophication, presence of suspended solids, water blooming and overgrowing of waters can be clearly seen from a bird’s eye view.

Surveying of the problem areas

Small and light UAVs provide data,that contribute to better understanding of the spatial and time processes in the watersheds. Use of UAVs is particularly warranted to determine dynamics of the rapidly developing processes in the areas where floods, active erosion and deforestation are typical. Early detection of silting and clogging of waters, as well as of the bank caving will allow you to eliminate the unwanted processes quickly and cost-effectively. The monitoring of ice conditions and snow melting will help to predict the volume of run-off and prevent the possible floods.

Mapping and design

Output data of the Geoscan surveying complexes is the full orthophotomaps and the three-dimensional elevation models. They are suitable for mapping of river and lake basins at different scales up to 1:500. A few hours of flight, automatic data processing, and you obtain the data corresponding to the results of the airborne laser scanning. Use of the Geoskan technologies will allow you to save time and costs for design and exploration work in the hydrological structures construction. Relevant cartographic materials are indispensable for planning of water protection zones and development of the aquatic ecosystem degradation stoppage projects.

Emergency monitoring

The largest advantage of UVAs is their economical efficiency and quick operation. It is possible to perform aerial survey within several hours even in the most difficult conditions where use of the usual aviation is complicated or impossible. Monitoring from the UAV in case of high waters or flood will allow to determine zones of flooding, discover the injured, estimate damage and plan emergency remedial actions. In case a flood is caused by ice clogging, detailed survey will help to find the most appropriate places of explosive charges placement for their removal. Data from the air will be useful upon mitigation of environmental disasters consequences. Images allow to determine all contaminated sites, and online monitoring helps to coordinate work of the ground-based teams.

Detailed 3D models of the area allow to carry out accurate hydrological analysis


Technology of generating detailed 3D models of the area with UAV provides wide opportunities for natural processes modeling. Compatibility of the initial data with GIS will allow you to use hydrological analysis tools. You will be able determine drainage direction and rate more accurately, calculate total drainage, distinguish watersheds and create water course networks. Precise three-dimensional spatial data will help to model various external conditions, processes of suspended particles and contaminants transfer.


Supervision over water users and water consumers will become much easier with the use of unmanned aerial vehicles. Systematic aerial survey will allow to control water withdrawal, detect unauthorized use of water basins and water conservation zones. According to the thermal survey results, you will easily determine places of unauthorized discharge of sewage waters or thermal springs outputs. With the help of our UVAs you will be able to perform visual examination of the waterworks for defects and damages detection.
