Geodetic survey on construction

For this service, geodetic surveys of reinforced concrete elements (columns, walls, crossbars, stairwells, elevators) are performed on the construction site and in the building. Average levels of entrances, communication details of floors (diameter, material, destination) and floor spaces are determined by geodetic service. The sub-levels of the floor, ceiling and crossbars are determined, the floor levels are distributed. Geometric dimensions of windows, door openings and passages are determined, profiles are created and geodetic points are balanced on each floor and marking works is carried out. Buildings can be designed both in a single plan and with all floors included. All normative documents on geodetic service are followed, plan and vertical works are performed with high accuracy.

It is necessary to carry out the determination of all the bias missed in the construction process, as well as the determination of the coordinates and height of the constructed object, and the determination of the dimensions of individual parts, according to the geodetic service. In this regard, we consider all the details and give the necessary advice, despite the methodologically overlooked criteria of the Client.

Topography service for agricultural fields

One of the widely used fields of topography service is agriculture. Topography is the study of the land, including its features and characteristics such as elevation, slope, soil, and other features. Topography is often studied using maps, which show the position of objects on the ground and their relationships to other things and elements. We have extensive experience in this field. Preliminary assessment of the area is important for agricultural activities and infrastructure (road (highway), electricity, water lines). Preliminary assessment is possible as a result of topographical survey. Land design is also an important issue, which requires topographical surveys. CASPIAN GEOMATICS LLC has signed numerous contracts for the purpose of carrying out engineering-topography surveys in the field for the cultivation of various agricultural plants. There are a number of methodological approaches applied in agriculture. These methods include tacheometric survey and GPS measurement methods, drone, integrated application methods, high-resolution aerospace data application methods. Our company has a special potential for applying all the mentioned approaches.

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. The type of topography can also affect how water is drained from the land, impacting irrigation and the types of crops that can be grown.

Usually, the investigation area for topographic survey by topographic service is methodically analyzed based on cartographic materials in advance. The surface structure of the area is analyzed and aerospace data with various resolutions are used. Then, the area is assessed in terms of applied methodology. At the next level, the issue of installing a geodetic reference point or using an existing state geodetic station by geodetic service is considered. Based on this, the issues of measuring, calculating and balancing geodetic reference points in static mode are solved. In these measurements, reference base points are selected (RTCM-REF GNSS points), connected and an averaged observation criterion is selected. The equipment is centered on the point and the height is measured. Installed benchmarks are calculated based on GNSS stations as a method.

Operational methods include terrestrial laser scanning surveying methods or aerial photography (LIDAR). In the application of photogrammetric methods, the issues of flight planning and its accurate execution are considered. To ensure the geodetic accuracy of the product, photogrammetric reference points are installed in the area, their coordinates and elevations are measured. The unmanned aerial vehicle is equipped with a high-quality camera, and high-resolution images are obtained. Aerial photos are processed, an aero triangulation model is created and balanced.
