In today’s data-driven world, businesses are increasingly realizing the value of aerial imagery and mapping. At Above and Below Drone Inspections (ABROV), we provide industry-leading aerial solutions in the United States to help you make informed decisions and optimize your operations.
Our services utilize the best commercially available aerial photography, exceeding the detail offered by satellite images. This clarity, combined with our commitment to capturing cloud-free imagery, makes ABROV a cost-effective option for a wide range of projects.
We offer regular updates of aerial imagery and maps, alongside historical imagery, providing valuable insights for businesses, farmers, and real estate developers.
We believe that a picture is worth a thousand words. An orthophotograph, a scaled aerial photograph with corrected elevation data, provides a wealth of valuable information. Points on the orthophotograph can be identified with precise coordinates, allowing for accurate measurements of lines and areas.
Orthophotos helps power your operations in the following ways:
The information contained within an orthophotograph is not limited to its visual representation. It acts as a comprehensive data set that can be used to interpret and supplement other types of data and thematic layers.
By correcting distortions caused by camera tilt and terrain elevation, orthophotos provide a true and accurate representation of the landscape, making them invaluable for a variety of applications.
ABROV utilizes the latest advances in Geographic Information System (GIS) technology to ensure the most efficient and cost-effective delivery of aerial data. Our fully digital workflow minimizes production time, while advanced data storage and management solutions enable us to deliver high-resolution imagery faster and smarter.
Orthophotos have a wide range of applications, including:
A raster containing elevation values can be used to create Digital Terrain Models (DTMs) or Digital Surface Models (DSMs).
Elevation models of all kinds are automatically interpolated on the basis of 3D point clouds extracted from aerial imagery. The best results for DTMs and DSMs are obtained by wide-angle aerial mapping cameras. A combination of image matching and data filtering must be applied in order to achieve the highest accuracy.
The Digital Terrain Model (DTM) depicts the surface of the bare earth. Using this type of data, orthophotos can be created, as well as volumes (cut-and-fill / stockpiling), slope and aspect can be calculated on their own. The quality of a DTM is determined by several factors, including the size of the pixels, camera geometry, and software parameters. It is important to capture break lines in a DTM when appropriate in order to achieve a perfect fit with the real world.
For applications requiring precise information about the shape, size, and orientation of landforms, a DTM is indispensable. The technologies can be used for a wide variety of purposes, including civil construction, water services, bushfire modeling, engineering, mining, topographic mapping, recreation, and defence.
With Digital Terrain Model Plus, we provide our top-of-the-line product. The product is produced by extracting 3D point clouds from imagery and reviewing them in 3D with skilled operators. A fully stereo-edited DTM, complete with 3D breaklines at steep changes in slope, ensures that the DTM is an accurate reflection of reality. This level of absolute accuracy is ideal for engineering projects that require a high degree of precision.
Buildings and trees can both appear on an elevation surface, such as a Digital Surface Model (DSM). Telecommunications applications use line-of-sight analysis to determine the path to the destination. The placement of antennas can be used for a variety of applications, including TV, wireless networks, mobile phone towers, microwave towers, and others.
We also incorporate elevations of natural terrain into our Digital Surface Models, along with the tops of trees, buildings, and other objects. Elevation models of this type are comparable to LiDAR ‘first-return’ models. Analysis of lines of sight, extraction of buildings, and obstructions on transmission lines can be performed with this program.
Stereo-edited, industry-standard digital terrain model
A digital terrain model created by our company represents a bare earth terrain with no buildings, vegetation, or other objects on it. The company can collect and provide breaklines upon request.
Through a combination of stereo-correlation and image-matching software, raw 3D data can be generated from aerial imagery. Using advanced automatic filtering algorithms, 3D points may be removed that may cover buildings, vegetation, or other non-ground objects.
Photogrammetric software requires RAW frames
Building modelers, mapping companies, surveying firms, property developers, and architects can all benefit from this information. The triangulated raw frame is the basis for many downstream data products. If an organization has in-house facilities for photogrammetric mapping, it may be advisable to use its own staff to create these products.
Raw frames are needed by agencies with in-house mapping departments to create products that require their special expertise, such as crop mapping or tree mapping.
