APPLICATION OF DRONE FOR SURVEYING IN VARIOUS INDUSTRIES
LAND SURVEYING: -
Drones are powerful tools to help in the mapping and surveying industry. They can effectively perform work for 3D mapping, land surveys, photogrammetric, and topographic surveying by flying above the ground. Surveying drone solutions can produce surveys with different degrees of accuracy, depending on the requirements of the project.
We at AEROWHIZZ create precise topographic maps and 3D models of areas with inaccessible evidence. Extensive land surveys and topographical surveys permit the most definite representation of cadastral maps, immediately and in a hassle-free manner. Our GIS crew then post-processes the data with photogrammetric software to generate deliverables like a detailed Digital Elevation Model (DEM), Digital Terrain Model (DTM), contours, brake lines, ortho-mosaic/ortho-imagery, interactive 3D Mode, and 3D reconstructions of land sites or buildings.
PRECISE MEASUREMENTS:-
The photogrammetric drone makes it possible to record any object with one or more images. This allows three-dimensional reconstruction to be made, in which the shape and position of the object are taken by measurements in the image.
Drones are commonly being used in industries such as surveying, mining, building construction, agriculture, and more, to measure all kinds of things, including area and volume. This is typically done with a method called photogrammetry. In basic terms, photogrammetry involves taking one or more photos, making measurements of the objects in the photos, and generating a three dimensional reconstruction based on those measurements.
This process would be quite complicated and inefficient to try to achieve on your own, but we can get accurate area or volume measurements from images that you take with your standard drone, there are a number of software options to allows to upload photo files, and would turn around and deliver measurable maps or 3D reconstructions based on the images .We can use these maps to find measurements of things such as land area or even the volume of objects or structures.
For absolute, centimeter level accuracy, you would need to go beyond the capabilities of a standard drone, and venture into sensors that can get through vegetation and other obstacles to give accurate ground level readings. This professional level of drones and camera sensors also offer georeferenced imaging to accurately connect images to geolocations.
TOPOGRAPHICAL SURVEY:-
Unlike traditional topographic survey data—which is basically a set of line work—drone surveys include an orthophoto, contour map, digital terrain model, and dense point cloud. The result is a highly accurate, visual dataset. All ready for analysis. Drones are now being used with laser scanners, as well as other remote sensors and digital cameras, as a more economical method to scan large and small areas. The possibility of drone remote sensing also eliminates any danger that crews of a manned aircraft may be subjected to in difficult terrain or remote areas. Drone data is already being used in many land development projects. From the early stages of planning and designing land subdivisions, through to preconstruction assessments, it’s also helping with progress tracking and final as-built.
Civil contractors are among the earliest adopters of drones. They say that drone-captured data, when used with ground control systems and processing software provides a quicker, easier, and safer way to produce digital terrain models and aerial site maps than previous methods. Using a surface-to-surface comparison, site terrain can be viewed against design to see where material should to be added or removed. These makes it easy to visually track changes in specific areas, or across the entire site, to make sure everything’s on track for successful completion.
URBAN PLANNING:-
As drone surveying lays a path toward well-established urban planning, with us at Aerowhizz you can quickly accumulate large amounts of real-time data. Our extensive aerial mapping services and state-of-the-art UAV technology have benefited government agencies and private developers while designing and analyzing existing social and environmental concerns. Aerial imagery has proven valuable in agriculture and environmental conservation projects as well. Through 3-D surveying, we can assist city planners, architects, tax collectors ,landscape and administrators for data collection.
Our drone cameras decked with high-quality features not only seize greater detail of the project when opposed to traditional inspection methods but also to do more economically. Drone cameras equipped with scanners produce three-dimensional representations as well. Our UAV technology, along with suitable sensors, obtain accurate topographical data that encourages clients to pay regard to energy efficiency, project progress monitoring, sewage design, utility establishment, detect illegal constructions, encroachments, etc.
ASSESSMENT OF BLASTING IN MINES:-
The use of UAVs can aid the blast improvement process by providing valuable feedback on the blasting process while decreasing the hazards to which personnel are exposed when collecting data. The valuable feedback described in this study included pre-blast structural mapping of pit walls and estimation, assessment of drill hole alignment, identification of problem areas during the blast using high-speed photography, post-blast measurement, comparison of the theoretical and actual powder factor, assessment of blasting impact on final pit walls, quality control of pre-split drill holes and an assessment of muck pile configuration. The performance of the operation can be closely tracked without significant time requirements. Work stoppages can be avoided because remote sensing techniques are employed to collect data. Additionally, data are collected at more flexible vantage points than ground-based remote sensing. Using UAV technology, it is also possible to cover larger and commonly inaccessible areas. This is particularly useful as mining progresses deeper in open pit mines and more benches become inaccessible. If issues develop in the top benches, they can be identified and addressed in a timely manner using UAVs and digital photogrammetry to ensure safety and efficient production without significant delays.
STOCKPILE MANAGAEMENT:-
In the mining and aggregates industries, stockpile inventory management is one of the primary use cases for drone surveying. Construction sites also use drones to survey their sites more quickly. The 3D maps generated from those flights collect actionable data, including stockpile volume calculations. By flying a drone to measure stockpile volumes instead of sending someone out to traverse a dangerous site, site management can track their inventories and site progress in a faster, safer, more reliable way. When you have accurate site surveys at your fingertips—and thus full oversight of your stockpile inventory—finding the answers you need gets a whole lot simpler. We provide dependable, highly accurate stockpile measurements. And you can measure progress as frequently as you want to fly. This influx of stockpile inventory data enables teams to tighten up worksite operations, which can include everything from financial forecasting and supply-chain management to accurate reconciliation.
3D MODELS OF CONSTRUCTION SITE:-
A drone is mainly used in the construction industry for surveying and inspection purposes. Drones are equipped with downward-facing sensors, such as RGB can capture a great deal of aerial data in a short time. During an aerial drone survey with an RGB camera, the ground, its features and buildings are photographed multiple times from different angles, and each image is tagged with coordinates. First, these highly detailed geotagged images can be used for assets and inspections, for example, of building roofs or hard-to-reach areas. They can also be used to monitor areas across long distances, such as vegetation rows, roads and railroads. Taking the technology a step further, photogrammetry software can combine the images to generate geo-referenced 2D maps, elevations and 3D models. These maps can be used to extract information such as precise distances, surface and volumetric measurements. Companies building and managing large infrastructure such as roads, railways, bridges, dams, water reservoirs, airports, industrial complexes, oil and gas operations, and power complexes have considerable potential to use drone data to optimize their operations. The complexity and scale of such projects exposes them to many challenges this technology can help solve, including long and costly surveys, early identification of construction mistakes, penalties for missing deadlines, miscommunication between stakeholders and contractors, and volumetric assessment. It can also help stakeholders efficiently survey to avoid financial liabilities post-construction due to lack of maintenance and resultant damage to the environment.
Drones can also open up new applications that were previously very hard or costly to access or closely track. Think of monitoring or inspecting hard-to-reach areas or of analyzing and optimizing rapidly changing environments such as construction sites.
MONITORING LAND CHANGES:-
Park, Coastlines and protected area managers would benefit from applying drones for monitoring impacts, which will result in spatially explicit and comprehensive high-quality data at very low cost. Combining orthophoto, DSMs and classified maps provide with high-quality information that can improve the knowledge on the landscape and lead to more efficient management. Furthermore, the low cost of operating a drone, as opposed to traditional fieldwork, allows for more comprehensive assessments, resulting in appropriate temporal and spatial scales. Monitoring of the management actions will also be easier using drones by automating the assessment of land cover changes in the landscape (e.g. by flying the same mission over time) or being able to re-visit the sites retrospectively if needed.
