Environmental Monitoring – Hydrography

Use of UAVs and modern equipment in the Fields of Environmental Monitoring and Hydrography

Accurate and Safe Monitoring

The use of specialized aerial and underwater equipment, combined with appropriate
sensors, cameras, and software, enables large-scale, detailed surveys in environmental and
hydrographic applications. These technologies provide precise maps and models, along with
telemetry data ready for immediate use. The goal is to significantly contribute to data
collection through an automated process, reducing costs and fieldwork time in hard-to-
reach and remote areas.

Environmental Monitoring with Productive Solutions

Case Studies

Integrated solution for bathymetric surveys

SPH Engineering’s sonar system is suitable for use in sea, rivers, or lakes, with main features being high productivity, easy access to hard-to-reach areas and the ability to choose from a range of single-beam/single-frequency, single-beam/dual-frequency and multi-frequency sonar systems, depending on the application. The main tool for producing depth measurements is a sonar system, installed on a DJI Matrice 350 RTK UAV.

Recording and mapping of habitat types

Aerial and underwater monitoring/mapping of habitats with Unmanned Aerial Vehicles and Underwater Unmanned Vehicles systems, using specialized thermal and non-thermal sensors to enhance environmental protection and preserve biodiversity.

Monitoring of protected areas

Wetland monitoring with DJI Matrice 350 RTK UAVs and acoustic and passive sensor systems, providing the capability for remote detection of illegal activities in the area of interest (day and night), with the aim of maintaining ideal conditions for the feeding and protection of wildlife and flora.

Use of innovative methodologies for air quality (AQ) monitoring

Collection of high-quality data with suitable sensors of various types (images/cameras, advanced detectors) for the development of 2D/3D maps measuring air quality and the concentration of particulate matter and pollutants, using UAVs in a specific area of interest.

Integrated Photogrammetric Software

Photogrammetry software is an essential tool in the fields of mapping and 3D modeling.

Photogrammetry software processes images captured by drones or other cameras and converts them into a high-precision 3D digital model and a geometrically corrected image mosaic. Typical products of a photogrammetric software are the production of 3D point clouds, the production of 3D meshes with textures, the production of 2.5D digital surface models and the production of orthophoto maps.
