A drone survey, also known as a UAV survey, is a method of surveying that uses unmanned aerial vehicles (UAVs), commonly known as drones, to capture images and data of a specific area or site. Drones are equipped with high-resolution cameras, GPS, and other sensors that allow them to capture aerial images and data with high precision and accuracy. Drone surveys can be used in various industries, including construction, mining, agriculture, and environmental management. The data collected from drone surveys can be used for mapping, 3D modeling, inspections, and analysis of land and structures. Drone surveys are becoming increasingly popular due to their cost-effectiveness, speed, accuracy, and safety. They can cover a large area in a short amount of time and provide a high level of detail that may not be possible with traditional surveying methods."

While drone surveys offer many benefits, they also have some limitations. Some of the limitations of drone surveys include: Weather conditions: Drone surveys can be affected by weather conditions such as high winds, rain, and fog. Poor weather conditions can reduce the quality of the data captured and increase the risk of accidents. Battery life: Drones have a limited battery life, which means that they can only fly for a limited amount of time. This can limit the coverage area and the amount of data that can be collected in a single flight. Legal regulations: There are strict regulations regarding the use of drones for commercial purposes, and these regulations can vary by country and region. Operators must ensure that they are complying with all relevant regulations. Technical issues: Drones can experience technical issues such as GPS errors, sensor malfunctions, and communication problems. These issues can result in inaccurate data or a complete loss of data. Privacy concerns: Drone surveys can capture images of people and private property, which can raise privacy concerns. Operators must ensure that they are respecting the privacy rights of individuals and complying with all relevant regulations. Cost: While drone surveys can be cost-effective in some cases, they can also be expensive, particularly for larger projects. The cost of equipment, software, and personnel can add up quickly. Overall, while drone surveys offer many benefits, it's important to consider their limitations and potential challenges before deciding to use them for a project.

Photogrammetry is a method that uses photographs for surveying and mapmaking. It is the science that helps in obtaining important information about the physical objects and environment through the process of recording, interpreting, and measuring the photographic images.

Photogrammetry is the process of image capture and processing to allow measurements to be taken from photographs. Commonly used at ground level for building facades and aerially from camera equipped drones, a number of survey and mapping tasks can be completed or benefited by this method.

From traditional 2D & 3D cad drawings and PDF layouts to photogrammetry outputs such as orthomosaics, point clouds and digital elevation models.

An orthophoto is a photogrammetrically orthorectified image product mosaicked from an image collection, where the geometric distortion has been corrected and the imagery has been colour balanced to produce a seamless mosaic dataset.

A point cloud is a set of data points in three-dimensional space that represent the shape and form of an object or environment. These data points can be used to create detailed 3D models of objects and environments.

A Digital Elevation Model (DEM) is a digital cartographic dataset that represents a continuous topographic elevation surface through a series of cells. Each cell represents the elevation (Z) of a feature at its location (X and Y).

Yes, we will deploy our drones to report volumes on any stockpile which is hazardous or inaccessible.

Bulking refers to the expansion of materials after excavation where shrinkage refers to the opposite effect when material is compacted. Also known as fill and cut.

The performance and type of drone, the quality of its components, the camera resolution, the height at which the drone flies, the vegetation, and the method and technology used to geolocate the aerial images can heavily influence the accuracy of drone survey mapping. At this point, it is possible to reach an absolute accuracy down to 1 cm and 0.7 cm/px GSD under optimal conditions with a high-end surveying drone.

Ground sample distance (GSD) in a digital photo of the ground from air is the distance between pixel centres measured on the ground. For example, in an image with a one-meter GSD, adjacent pixels image locations are 1 meter apart on the ground.

This can range from historic aerial photography which can be used as evidence in a boundary survey, to high resolution drone survey images and video, which can be processed into 3D maps, models and orthophotos.
