TOPOGRAPHY (GEODETIC) SERVICES

Exploration and prospecting, geodetic and topographical survey are one of the main activities of CASPIAN GEOMATICS company.

One of the widely used fields of topography service is agriculture. A preliminary survey of the relief of the area is essential for economic activities and infrastructure. Design works also require topographical surveys. Our company has signed numerous contracts for the purpose of carrying out engineering topography surveys on geodetic service for the cultivation of agricultural plants. There are a number of methodological approaches applied in the field of agriculture. This includes topographical surveys carried out by GPS survey and integrated application methods.

Firstly, topgraphers methodically analyze the investigation area for topographic surveys (exploration and prospecting) based on cartographic materials. Secondly, we analyze the surface structure of the area and use aerospace data with different resolutions. After that, we assess the area in terms of applied methodology. At another level, we select the reference base points for this measurement (RTCM-REF GNSS), connect them, and select the observation criterion. We calculate benchmarks based on GNSS stations as a method.

Topography service is widely used in the following fields:

landscape design and military, planning, agriculture and forestry, irrigation, hydrotechnical facilities, hydrographic objects, underground communication lines detection.
topographic surveys, determination of geometric indicators for the object, land subdivision, modeling, volume calculation.
design (water supply, sewerage, pumping station, power lines, etc.), transport, subsidence and slope determination.
geological and hydrogeological, geophysical surveys, topographic mapping and updating, natural resources study, mining, oil and gas industry.

Many sectors rely on accurate geodetic control (Floodplain mapping, Spatial management, Engineering and Construction, Geographical sciences, Agriculture). Researchers often study topography using maps, which display the position of objects on the ground and their relationships to other elements. Assessing the area beforehand is crucial for agricultural activities and infrastructure development. Topographical survey enables this preliminary assessment. Moreover, the topography of an agricultural area can significantly impact the crops grown and the farming methods used. For example, areas with steep slopes may be more suited to terraced crops. Meanwhile, flatter areas are better for large-scale farming operations.

Drone services

High-resolution orthophoto mapping based on aerospace data.
Creation a digital elevation model with high accuracy.
Drone-based topographic mapping, volume calculations.
Geodetic provision of drone-based surveys and surveys conducted by other methods.
Digital elevation model (DEM) and digital terrain model (DTM).
Georeferencing of images.

Operational methods involve using either terrestrial laser scanning surveying or aerial surveying (LIDAR) to prepare a topographic map. Firstly, a flight is planned in the application of photogrammetric methods by topographic prospecting works. After that, the exact execution of the flight is planned. Thirdly, geodetic reference points are installed in the area to ensure the geodetic accuracy of the product. Fourthly, their coordinates and elevations are measured. As a result, high-resolution images are obtained by equipping the Unmanned Aerial Vehicle (UAV) with a high-quality camera for the purpose of topographical prospecting works (surveys). In conclusion, we process the aerial photo, create the model, and regulate it.

HSE

Generally, we strictly adhere to safety techniques in geodesy. Methodologically, HSE specialists assess the risks in the project area and minimize all potential dangers. This ensures the safe execution of work. As part of the procedure, specialists first inspect the project area, prepare the necessary documents, and present them to the Client.
