Do I Need a Drone Survey?
You might be wondering if a drone is preferable to those traditional methods. There are numerous ways that they are more beneficial. Find out more can acquire data at vantage points that are not accessible to humans, especially those areas with challenging terrains. You don't have for human operators to measure points in hazardous locations physically. However, those traditional methods do require pre-planning before achieving the site. When a drone flies over a location, it can capture the same level of data in a shorter timeframe. Drone surveying allows the surveyor to get data more safely and quickly than those traditional methods. If you're after a more efficient way to survey those areas, it may be time to contemplate using a drone survey.

How Accurate Is really a Drone Survey?
If you are worried about the accuracy of a drone survey, these units are incredibly accurate. In many cases, you may expect drone surveys ahead within two centimeters of the specific location. Most drones are even more accurate than those measurements. When you work with a professional drone surveying company, you can expect these kinds of results. Remember that they have access to better equipment and that always leads to more accurate outcomes. Plus, the kind of drone, quality of the camera, flight height, and ground cover can all influence the survey results.

HOW WOULD 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 in to the software system. From then on, the operator must ensure that buildings or other hazards usually do not obstruct the flight path. When the coordinates are entered, the drone will need off because of its survey. In some instances, the operators can maneuver the drone from the remote control, or the device could have autonomous control of the flight path.

JUST 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 would have to be completed and the period of time to finish the job.

What types of Deliverables IS IT POSSIBLE TO Achieve With Drone Surveying?
With regards to the surveying software and data sensors, a drone can perform various kinds deliverables.

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

3D Orthomosaic Maps
Ever since the first maps were created, 2D projection is a problem. With one of 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 into a 3D map, which helps to provide better topographic data. In the construction industry, drones use Building Information Modeling (BIM) software. During each construction process step, a high-resolution 3D map is captured and weighed against the BIM objects. This allows 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 fully capture datasets related to large objects like construction sites and buildings. Once that data is collected, 3D software can make a model for more in-depth site analysis with BIM.


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

LiDAR Point Cloud
LiDAR can help a drone to look out of trees and ground cover. This process uses lasers to fire at a particular target to see in complete darkness or with obstacles in the manner. 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 that can be collected is a multispectral map. With that, images capture data within a specific wavelength range on the electromagnetic spectrum. These maps provide better insights to those that need assistance with their crop and agriculture management.
