![]() ![]() The micro 4/3 sensor on the Mavic 3 Enterprise is significantly larger than the 1 inch sensor on the Phantom 4. A mechanical shutter will dramatically improve your drone models because you won’t have rolling shutter issues which create blur in your images when you are flying. The reason that this drone is awesome for mapping is because it’s one of a handful of drones that has a mechanical shutter. The Mavic 3 Entreprise is a long-awaited replacement to the DJI Phantom 4, which has long served as the workhorse of drone mappers worldwide. Top 5 best drones for mapping and surveying 1. Not all drones are made for the job, so here’s a short list of the best drones for mapping and surveying. However, doing a drone survey is going to take more than just buying any standard commercial drone. Not only do drones make surveying jobs easier, but they can also produce data and models that are more accurate. By using a drone, surveyors no longer need to spend several days or weeks walking through the survey area and taking manual measurements. Spherical coordinate system: WGS84 (EPSG: 4326) This coordinate system is commonly used for more traditional "desktop" mapping tools.Of the many commercial uses of drones, mapping and surveying seem like some with the most natural fit. ![]() This is great for importing into web mapping systems such as Google Earth or Mapbox. We also make exports available in the most commonīy default, most exports are generated using the Web Mercator projection (EPSG: 3857). Most common file format accepted across Construction & Mining software formats. xyz point cloud that contains RGB information (XYZRGB). Includes a.TWF file with the georeferenced metadata.įile format suited for 2D analysis in GIS software such as ArcGIS or QGIS.Ĭan be used in AutoCAD, ArcGIS, Global Mapper, Applied Imagery, or similar software. ![]() TWF file with the georeferenced metadata.Įasy to share through any standard image software such as Windows Photo Viewer or Preview. Mapping files will be delivered in any of the following Autodesk compatible formats:Īvailable for all 2D layers: 2D Map, Elevation, and Plant Health. We can output our data in a number of formats to suit our clients or provide HTML codes for embedding into websites should that be required. Most online satellite mapping can be up to four years out of date with major developments and buildings missing.Īll our maps are georeferenced and with the inclusion of ground control points the maps are built with a high degree of accuracy. That's up to twenty times higher resolution than online satellite imagery. Global Drone Surveys provides fully integrated mapping services for our clients, using the latest technology we are able to produce mapping resolutions down to 1.7cm / px if required. They are much more efficient than traditional methods, and can be done without putting people in dangerous situations. It also has the advantage of being able to cover large areas quickly.īoth drone mapping and photogrammetry are relatively new technologies that are revolutionising the way we survey land and inspect infrastructure. It is accurate and relatively easy to do. Photogrammetry is a useful tool for many different applications. This model can be used for things like planning construction projects, measuring distances and heights, or studying topography. The photos are then processed by special software that stitches them together to create a 3D model. This can be done with any camera, but drones are often used because they can take many pictures from different angles quickly and easily. It is similar to traditional surveying, but instead of using measurements to create a map, it uses photos to create a 3D model. Photogrammetry is the process of creating a 3D model from photographs. These images are then stitched together to create a high-resolution map. This technology is often used for surveying land or inspecting infrastructure.ĭrone mapping involves flying a drone in a grid pattern over an area to capture overlapping images. Drone mapping and photogrammetry is the process of using drones to capture images that can be used to create detailed maps. ![]()
