Surveying & GIS

Surveying with our drone offers enormous potential to GIS professionals. With a drone, it is possible to carry out topographic surveys of the same quality as the highly accurate measurement collected by traditional methods, but in a fraction of time. This substantially reduces the cost of a site survey and the workload of specialists in the field.

CX is a complete unmanned or autonomous system, that captures aerial data with downward-facing sensors, such as RBG or multispectral cameras, and LiDAR payloads. During a drone survey with an RGB camera, the ground is photographed several times from different angles, and each image is tagged with coordinates.

From this data, photogrammetry software with CX series drone can create geo-referenced orthogonal, elevation model or 3D model of the project area. These maps can also be used to extract information such as highly accurate distances or volumetric measurements.

Unlike manned aircraft or satellite imagery, CX drones can fly at a much lower altitude, making the generation of high-resolution, high-accuracy data, much faster, less expensive and independent of atmospheric conditions such as cloud cover.

Reduce field time and survey costs

Capturing topographic data with a drone is up to five times faster than with land-based methods and requires less manpower. With CX series and PPK geo-tagging, you also save time, as placing numerous GCP’s is no longer necessary. You ultimately deliver your survey results faster and at a lower cost.

Provides accurate and exhaustive data

Total stations only measure individual points. One drone flight produces thousands of measurements, which can be represented in different formats (point cloud, DTM, DSM. Contour lines etc). Each pixel of the produced map or point of the 3D model contains 3D geo-data.

Land Surveying / Cartography, Management & development

CX drones generate high-resolution orthomosaic and detailed 3D models of areas where low-quality, outdated or even no data, are available. They thus enable high-accuracy cadastral maps to be produced quickly and easily, even in complex or difficult to access environments. Surveyors can also extract features from the images, such as signs, curbs, road makers, fire hydrants, and drains. After post-processing with photogrammetry software, these same images can produce very detailed elevation models. Contour lines and break lines, as well 3D reconstructions of land sites or buildings.

Aerial images taken CX drone greatly accelerates and simplify topographic surveys for land management and planning. This holds true for site scouting, allotment planning and design, as well as final construction of roads, buildings and utilities. These images also provide the foundation for detailed models of site topography for pre-construction engineering studies. These generated data can also be transferred to any CAD or BIM software so that engineers can immediately start working from a 3D model.

Map inaccessible areas

CX aerial mapping drone can take off and fly almost anywhere. You no longer limited by unreachable areas, unsafe steep slopes or harsh terrains unsuitable for traditional measuring tools.

Stockpile Volumetric measurements

With CX 3d mapping software, it is also possible to obtain volumetric measurements from the very same images. This fast and inexpensive method of volume measurement is particularly useful to calculate stocks in mines and quarries for inventory or monitoring purposes. With a CX drone, surveyors can capture many more topographic data points, hence more accurate volume measurements. They can also do this in a much safer way if they had to manually capture data by going up and down a stockpile. Since drones are capturing the data from above, operations on site won’t be interrupted. The short acquisition time enables capturing a site snapshot at a specific point in time.

Urban Planning

The development of increasingly dense and complex urban areas requires intensive planning and therefore time-consuming and expensive data collection. With CX, urban planners can collect a large amount of up-to-date data in a short period of time and with far less staff. The images produced in this way allows planners to examine the existing social and environmental conditionals of the sites and considers the impact of different scenarios. At this point, it is possible to reach an absolute accuracy down to 0.4 inches and 0.3 in/px GSD under optimal conditions with a higher-end surveying drone.
