Do I Need a Drone Survey?
You may be wondering if a drone is better than those traditional methods. There are numerous ways that they're more beneficial. These drones can acquire data at vantage points that aren't accessible to humans, especially those areas with challenging terrains. There is no need for human operators to measure points in hazardous locations physically. However, those traditional methods do require pre-planning before reaching the site. When a drone flies over a location, it can capture the same quantity of data in a shorter time frame. Drone surveying allows the surveyor to collect data more safely and quickly than those traditional methods. If you're after a more efficient solution to survey those areas, it may be time to contemplate using a drone survey.

How Accurate Is really a Drone Survey?
If you are concerned about the accuracy of a drone survey, these units are incredibly accurate. Oftentimes, you can expect drone surveys ahead within two centimeters of the actual location. Most drones are even more accurate than those measurements. When you utilize a professional drone surveying company, you may expect these types of results. Remember that they will have usage of better equipment and that always results in more accurate outcomes. Plus, the kind of drone, quality of the camera, flight height, and ground cover can all influence the survey results.

HOW CAN YOU Map a Drone?
Many surveyors spend hours planning their flight paths. They want to make sure that all of the coordinates and perimeters are accurate for an effective survey. Depending on the drone, all that information should be entered into the software system. From then on, the operator must make sure that buildings or other hazards do not obstruct the flight path. Once the coordinates are entered, the drone will take off for its survey. Sometimes, the operators can maneuver the drone from the remote control, or the device could have autonomous control of the flight path.

How Much Does a Survey Drone Cost?
More often than not, a drone survey can cost anywhere between $30 to $120 per acre. However, those costs may differ depending on the type of survey needed to be completed and the period of time to finish the work.

What Kinds of Deliverables IS IT POSSIBLE TO Achieve With Drone Surveying?
Based on More helpful hints surveying software and data sensors, a drone can perform several types of deliverables.

2D Orthomosaic Maps
Many drones focus on 2D photogrammetry mapping, such as for example an Orthomosaic map. Once the drone flies above the ground, it can capture hundreds of photographs. Those photos are stitched together to produce a 2D Orthomosaic map. Each point on the map contains an X/Y axis and color information. These maps feature unformed scales and can be used to measure distances between specific points. Many professionals consider these maps to be an accurate representation of the planet earth?s geological surface.

3D Orthomosaic Maps
Ever since the first maps were created, 2D projection has been a problem. With these 2D images, the image is flattened at first glance, leading to distorted regions on the map. 3D Orthomosaic maps can fix some of those issues. They collect several hundred photos and compile them right into a 3D map, which helps to provide better topographic data. In the construction industry, drones work with Building Information Modeling (BIM) software. During each construction process step, a high-resolution 3D map is captured and compared with the BIM objects. This enables for any discrepancies to be identified and resolved.


3D Models
Drones are also effective at collecting data to create 3D models. These machines are airborne scanners to capture datasets linked to large objects like construction sites and buildings. Once that data is collected, 3D software can create a model for more in-depth site analysis with BIM.

Thermal Maps
The drone imagery from an aerial drone may be used to identify areas with abnormal signatures. The drone inspection can survey complexes, facilities, campuses, cities, and military bases for these thermal images. Warm water lines, supply water mains, supply steam pipes, and condensation return lines could be accurately monitored with the aid of a drone survey. When a concern is discovered, leaks can be repaired, saving energy loss along the way.

LiDAR Point Cloud
LiDAR can help a drone to see through trees and ground cover. This technique uses lasers to fire at a specific target to see in complete darkness or with obstacles in the way. When the drone has this software, data is collected to make a high-density point cloud for the survey site.

Multispectral Map
Another type of data which can be collected is a multispectral map. With that, images capture data inside a specific wavelength range on the electromagnetic spectrum. These maps provide better insights to those who need assistance with their crop and agriculture management.
