Bathymetry
Our company has been offering comprehensive surveying services to both private individuals and companies for 13 years.Bathymetry is a science that studies the shapes of reservoirs and watercourses, as well as seas and oceans.
The data is presented using contour maps, cross-sections, bathymetric maps, digital terrain models and 3D models. A hydroacoustic measurement method is used to create a visualization of the area beneath the water surface. Our bathymetric measurement system is based on versatile ultrasonic technology. High-frequency acoustic waves are sent from the emitter to the bottom of the water body. The distance is determined by differential measurement of the signal speed per unit of time.
Oprócz echosondy, innowacyjny system zawiera precyzyjny odbiornik GNSS. Ta modułowa konstrukcja zapewnia każdemu pomiarowi głębokości współrzędne poziome, określone z dokładnością do pojedynczych centymetrów. W rezultacie siatka punktów pomiarowych dna zbiornika jest efektywnie mierzona w krótkim czasie.
The bathymetric sensor is mounted on a floating platform that can be easily controlled from land. In order to perform reliable and complex tests, an autonomous route is generated in the appropriate application.
An unmanned surface vehicle with a bathymetric sensor is extremely helpful, especially in hydrographic studies of sediment ponds, where the involvement of a manned boat may be dangerous due to the irregular bottom and the activity of dredging machines.
Compared to traditional pond surveys using a survey pole, bathymetric USV not only provides better accuracy, but also increases the efficiency and safety of the measurement session.
The survey data set can be presented in a variety of ways - from elevation and color depth maps to integrated with photogrammetric terrain models, offering engineers the ability to calculate complex excavation volumes and submerged piles.
The main advantages of the bathymetric system in our company:
- Fast and safe one-person measurement,
- High coordinate accuracy,
- Possibility to combine bathymetric data with photogrammetric models,
- Comprehensive presentation of the bottom of a reservoir or river along with the surrounding area,
- Detection of sediment accumulation in hard-to-reach places,
- The frequency of measurement is adapted to the customer's needs,
- A clear and easy-to-interpret way of presenting data.
Our products
As a result of appropriate data processing, we can offer several products - both for full 3D and classic 2D work. These are, among others, orthophoto-maps, projections, cross-sections, longitudinal profiles and various thematic maps.
Point cloud
A point cloud is a multi-million point set that is a geometric representation of a scanned object.
Clouds are acquired either indirectly (photogrammetry) or directly (3D laser scanning). There is a possibility to provide a cloud that is a combination of both technologies, which allows for full imaging of a scanned object.
Point clouds are usually so dense that they appear to form a continuous surface. The density of a point cloud depends on the class of scanner, its accuracy settings, and the distance from the object being scanned. Each point has a colour assigned to it, which makes it easier to identify the reconstructed objects in the cloud. Unlike the photogrammetry technique, the acquired point cloud has a scale, so measurements can be performed on it immediately without the need for fitting.
Upon client’s request, the cloud is provided in Polish Coordinate System 2000. Available data exchange formats include: LAS, LAZ, PLY, XYZ, RCP and RCS. Point cloud can be conveniently viewed and measured in Autodesk Recap software. Additionally, it can be loaded into AutoCAD, Microstation, Cyclone or ArcGIS software.
Application: Design, architectonic, visualization and planning purposes
3D model with superimposed texture
3D model with superimposed texture: OBJ, STL, PLY, FBX and 3D PDF.
It is possible to load the file into programs such as Revit, Inventor, Meshmixer, Infraworks, 3D Studio Max and Sketchup and print it on a 3D printer.
Application: Visualization and planning purposes
Orthophotos
Orthophoto-map is a cartometric image acquired as a result of processing a photo taken by an unmanned aerial vehicle (BSP, drone). It is a comprehensive source of knowledge about a given space.
The image obtained from the drone is characterized by a high resolution of the field pixel (at the level of 1 cm), which allows us to identify even the smallest elements of the infrastructure. In contrast to the aerial photo, orthophoto-map has a uniform scale for the entire surface of flat field. The use of drones in surveying work enables the preparation of an orthophoto-map of a given area even of several hundred hectares. The product is georeferenced which makes it possible to read the map in the appropriate software and to make the project and add resources in the form of the basic or register map.
It is possible to load maps with accurate georeferencing into such programs as AutoCAD Map 3D, AutoCAD Civil 3D, Microstation and ArcGIS.
Uses: spatial planning, land registry modernization, environmental analysis, designing construction works, site visualization, detecting changes in the natural environment, creating documentation of natural disasters, quality control of maps and cartographic data
Numerical land coverage model
Numerical coverage model provides precise representation of the existing field, which generates a wide range of possibilities for analysis, comparison, calculation, design and spatial planning.
The available formats are: GEOTIFF, XYZ, LAS and LAZ. It is possible to import the file to AutoCAD Map 3D, AutoCAD Civil 3D, ArcGIS and Microstation.
Videos and photos with editing
Tworzymy filmy w dowolnej jakości – nawet do 4K. Dokumentacja video pozwala na precyzyjną inspekcję
We create films in any quality - even up to 4K. Video documentation allows for a precise inspection of a specific element. We also offer visualisations in the universal MPEG4 (MP4) format which enables a comfortable presentation of an object to a Client, investor or supervisory inspector. We offer taking a very large number of photographs (from several dozen to several thousand - depending on the size of an object) with a resolution of up to 36 MP.
The photos are in a customized format.
Application: Very detailed documentation of an object and its changes over time
We deliver films in MP4 or AVI format.
Application: Very detailed documentation of a specific component
Calculations of volume, area and length
The information is supplemented by an appropriate graphical presentation, authenticating the calculated value.
We use low-altitude aerial photogrammetry technique with the use of non-metric images. The technology involves processing digital images to a 3D point cloud, which is a spatial, finite representation of field consisting of points with coordinates X, Y, Z and the colour value of each point (pixels).
In order to calculate the volume of earthworks, we create numerical field models in the form of TIN (Triangulated Irregular Network) grid in AutoCad Civil 3D software.
The computational task is to compare the created numerical field models (TIN meshes). The difference between the 3D surfaces is obtained and then the values of excavations and embankments between the models are calculated.
Cross-sections and projections
An interesting product for documenting building structures is the orthometric projection.
It is a fully cartometric representation of a specific plane, e.g. a façade, a building front, an acoustic screen or a retaining wall. Saving to a TIFF file enables us to review an object in high resolution. Depending on the Client’s wish, cross-sections may be saved to CAD (DWG, DXF) or PDF files.
Application: Creating a clear architectural and construction inventory (mainly for planned renovations).
3D modelling
3D modelling is a process in which we use software to transform a mathematical representation of an object into a 3D model. The created object is called a three-dimensional model used in branches such as mining, industry, construction or architecture.
3D modelling facilitates communication of ideas, is used to create interactive positioning of objects or surfaces that represent the actual design. It provides control of the real condition with design parameters. It allows us to create a part of a physical object in a very fast time, so we can make analyses of physical properties and then update the model as needed.
Available data formats are: DWG, DXF, DGN, STP and others. Models (solids) are created by us on the basis of a point cloud to maximally facilitate the Client’s work in such programs as AutoCAD Civil 3D, Inventor, Revit or Archicad. Processed buildings, machines or pipe networks give the possibility to work comfortably in the environment familiar to the designer.
