With drone surveying, McCord Engineering Geospatial Services can collect high-density LiDAR data used to create a 3D model. Data can be delivered to you in the form of topographical maps, point clouds, cross sections and mosaics; in a variety of file formats.  This is especially helpful in hard-to-reach locations.


[Disclaimer: We are not licensed or certified surveyors/engineers. We are a data collection service that owns and uses cutting-edge technology to save your company time and money.]

TDP Workflow:

  1. Define Job Area (.kmz files)
  2. Define Deliverables
    1. Point cloud
    2. DTM
    3. Mosaic
    4. Topography
    5. Cross-Sections
  3. Confirm Property Permissions
  4. Check for COA Requirements
  5. Plan Mission
  6. Set Ground Control
  7. Fly Property
  8. Process Data
  9. Deliverables
  10. **Request Feedback to Refine Deliverables

We use high-res digital cameras for photogrammetry , and have a high-quality LiDAR. Either of these technologies give you accurate 3D measurements of surroundings you need mapped.

When we are finished, you get a full map, measurements of objects specified, and any files we created in collecting your data.

Drone Benefits to Surveying:

  1. Low-cost data collection
  2. High-density point clouds
  3. Drone point clouds allow for:
    1. All-inclusive orthomosaic of work area
    2. Fewer manual surveying points
    3. Precise measure of specific points

In addition, drone data allows for:

  1. Topographical mapping
  2. Watershed & flood analysis
  3. More precise line work for engineers

Drone surveying flyovers can help surveyors more precisely measure elements conventional surveying wouldn’t pick up without many hours of field labor. This in turn can help optimize procedures for saving money in equipment and man-hours.


Just listen to what Henry Mayo of Joe Orr/Baseline had to say about it in this company circulation:

McCord Engineering Geospatial Services does all the data collection for you. We handle the aircraft, insurance, FAA, etc. . . You show us the site, we’ll get you the data.

It is important to note we are not certified surveyors, nor do we do line work. We are simply another tool to help the industry collect more usable, more valuable data.

Drone LiDAR strengths?
We can fly over hard-to-reach locations and areas of heavy road traffic. We can help small companies obtain large projects and any company can use us for smaller areas. We can also penetrate heavy tree canopies, finding ground points in otherwise impossible to reach locations.

Drone LiDAR weaknesses?
Our LiDAR doesn’t penetrate water and it can’t map items buried underground.

What kind of density can we produce?
We collect 700,000 shots/sec. That produces a point density of 500 points per square meter, or 50 points per square foot.

What is our accuracy?
We have a 2cm horizontal and 5cm vertical accuracy.  Total volumetric accuracy is within 3%.

How do you keep the accuracy?
With LiDAR or photogrammetry, we use ground control points for absolute point cloud positioning (we make sure the data matches your specs).

How do you check accuracy?
In addition to ground control points, we use visual landmarks and other known “check points” to verify accuracy within the point cloud.

Are Drones legal to use in commercial business?
The rules relative to drones in commercial business are changing on a regular basis. As a drone company it is part of our service to stay current on the FAA requirements for operation. As of the start of 2017, you can operate drones for business if you have:

  1. An FAA Exemption 333 or Part 107 license
  2. A registered “N-numbered” aircraft
  3. Appropriate COA, certificate of authorization for your flying location
  4. Permission from the owner or authorized agent of the property

Drones can be operated in most locations with what is called a “Blanket COA”. This COA is part of the 107 license. Some areas, such as close to airports require special authorization from the FAA. This authorization can take from a few days to a few weeks depending on the specific location.

There are many more details relating to the legal and safe operation of drones in US Airspace. We can provide more details upon request. The most important detail is it is completely legal to operate when you follow the appropriate FAA regulations.

Safety?
We operate at all times with our authorized Pilot and “Observer”. If the job warrants, we add extra crew members to keep needed areas clear and safe for flight.

The aircraft we use have several safety features in the case of technical issues during a mission. We can supply further details upon request.

Liability?
McCord Engineering Geospatial Services carries at least $2 million in Liability insurance. If your company requires a specific level of insurance coverage we can make sure to match or exceed that level before starting work.
