![]() This means that it’s possible to make measurements associated with location, distance, and area. ![]() All the objects and features in an orthomosaic are scaled and can be georeferenced. ![]() Through a process called photogrammetry, these many images are then turned into a single complete image, called an orthomosaic. Drone mapping allows a level of highly detailed data collection across a large area that isn’t possible through satellite images or traditional ground surveying.ĭrone mapping works by taking many aerial images of an area of interest. As it’s name suggests, it involves mapping an area of your choice with a drone to produce all kinds of useful outputs like an orthomosaic, digital elevation models and 3D models. So what is drone mapping and how can you use it?ĭrone mapping (sometimes called drone surveying) is a fairly straightforward way to collect data with drones. ![]() From real estate, to environmental science to mining, drone mapping has been a game changer and as technology advances, it’s becoming useful in more and more fields. While drones can collect data in many different ways, one of the most widespread methods is drone mapping. In Japan in 2017 they first introduced earthmoving equipment manufacturer’s using drone imagery coupled with powerful 3D models to operate unmanned digging equipment on land cut and fill sites.Part of what makes drones such a valuable technology is their ability to collect large volumes of data. Our drone data is up to date and more detailed that satellite data collected from Google Earth or Google Maps.įor land and mining applications 2D photo-mosaics and 3D Digital Surface Models are becoming an integral part of the day to day operations, progress monitoring and volume measurement of materials.ģD Digital Surface Models show the topography and the exact landscape contours. These 2D and 3D maps can be compared to older and newer versions to record change and calculate length, area, volume, cut/fill, and elevation between two or more dates.īelow are some current industry sectors and applications for drone flights to collect images for 2D photo-mosaics and 3D Digital Surface Models: Industry Sectors Using this information combined with additional oblique side images taken at 30° and 45 ° angles the software can also produce a 3D model that can be viewed from any side or orientation. The overlapping geo-referenced aerial images are stitched together in the software to produce a 2D Orthomosaic - 2D photo-mosaic. We fly at a consistent height in a lawnmower path with the overlap of images to the front and the side normally set at 75-80% for most jobs.ĢD orthophotography can be used to measure real distances, because it is an accurate representation of the Earth's geographic surface. The flight altitude and image overlap is determined by the type of industry and the results required. The maximum resolution of the images starts at 5cms per pixel but this can be increased to 1cm per pixel. The higher altitude we fly, the more acres of land we can cover, but the lower we fly the more detailed the image. The processing and analysis of this aerial imaging data is done quickly on powerful servers to produce an accurate useable map in various file formats for our clients to use or to import into GIS, CAD compatible software - ArcGIS, Global Mapper, QuantiumGIS, AutoCAD, 3D Reshaper, Trimble, Quick Terrain Reader, Bentley and CC Viewer. This can form a 2D Map or 3D Model.ĭepending on the client requirement, we use either PC based or cloud based drone mapping software suppliers Pix4D Mapper and DroneDeploy to produce 2D photo-mosaics and 3D Digital Surface Models in the form of geo-referenced Orthomosaics, DSM, DEM, NDVI, and Point Clouds. Photogrammetry simplified is a mapped display of data stitched together, based on still images and their positions/angles determined by their Geo positioned metadata. We can measure and map hard to reach areas like, quarries, landfill sites and open cast mines. Drone Photography Services fly our drones (UAV’s) with a high-resolution camera to collect 20 megapixel aerial photographs for a wide variety of commercial photogrammetry mapping uses. ![]()
