Laser Survey
Small area LiDAR scanning
Laser Survey has specialized in small area LiDAR scanning all around the world.

Laser Survey started as an idea form one of its founders who has worked many years as chief surveyor in Africa. At the time he had many projects surveying roads for upgrade.

Many times it was hundreds of kilometers and the idea of scanning them was not far away, but every time he contacted an aerial scanning company, the answer was the same. The setup costs for plane coming from Europe was minimum 60.000,- euro and that a job of 100 km corridor

mapping wasn’t interesting due to its small size.

The idea
of a down sized LiDAR system was born. The objective was to develop a system that could undertake 100 km of road surveying in a corridor of 100 meter width, in a country sub Sahara at the costs not more than 80% of a traditional survey. In order to achieve that the system needed to be portable, easy to use and as accurate as other systems in the marked.

To reduce the setup costs the system needed to be small enough to be transported as hand luggage, and if that could include the aircraft, we would also be able to reduce the running costs. As the complete system with

scanner and camera no larger than a cabin suitcase was developed and by choosing a paraplane as platform, it was possible to pack it all in standard suitcases only paying a small fee for overweight.

The future
It was soon clear that there was a much wider use for the system than just road corridor surveying in Africa. The system has proven its worth several times both in Africa but also in other parts of the world and the development continues. Several different options for choice of platform has been developed, latest the use of UAV, but also the performance of the system is constantly developed making sure that Laser Survey is always offering the best solution.

Multiple platforms

The LAMS system from Laser Survey is so small and flexible that it fits with a wide variety of platforms.

Paraplane
The paraplane can be packed in standard suitcases and operate from smaller fields close to the survey site. The drawback is its sensibility to weather and small operational radius.

Gyroplane
The gyroplane is a very stable surveying aircraft with many of the same characteristic as Helicopter but with a fraction of the air time costs.

Helicopter
For helicopters there are two options. Either the system can hang underneath the helicopter in a sling, or it can be fitted to the side in a pod.
The fitting of the LiDAR system using the sling option takes literally only minutes and is a good option for small areas.

UAV
The LAMS system is so small that it can even be flown with unmanned aerial vehicle (UAV).

Other options
The LiDAR system can be carried by any low speed air craft or even be fitted on a vehicle for mobile LiDAR scanning.

LiDAR scanning is 4-5 times more accurate than traditional surveying.

Laser Survey’s tests has shown that LIDAR scanning is 4-5 times more accurate for volume calculation compared with traditional surveying. This makes LiDAR scanning an obvious choice and in combination with Laser Surveys low setup costs it makes it a realistic opportunity for open pit mines, construction companies and others that needs an accurate estimate of volumes for i.e. piles, baffles etc..

High Quality
The system might be small, but the accuracy is high.  

The LAMS system is developed with support from the Danish National Space Institute and Technical University in Copenhagen.
The gold has been to develop a small and portable, but with the same or better specifications than other aerial LiDAR systems from larger system manufactures as Optec, Leica and TopoSys.

Test
The accuracy tests has been carried out in normal operation mode, meaning that no manual work has been done to improve the result.

Low Cost
Laser Survey has a different approach to aerial LiDAR scanning.

The different approach means that setup costs are significantly smaller than what is normally expected.

The system is so small that it can easily be transport as standard luggage and as is does not require calibration on site, the setup costs are comparable to setup costs for traditional land based surveying.

LAMS Specifications    The concept of LAMS is to bring LIDAR surveying to remote areas by filling the gap between terrestrial survey and traditional LIDAR survey. The focus is laser surveys at competitive prices.

The system has been calibrated and tested on a test site in Hillerød, Denmark.
The test site consists of 2 km secondary road in a sub urban area. More than 200 control points was taken on and along the road.

The post processing of the LiDAR data was done automatically without manually enhancing the result and without use of reference points. The concept of LAMS is to bring LIDAR surveying.

As a check the test has been completed several times over a period of years, and the result has been the same or better every time. The concept of LAMS is to bring LIDAR surveying.

In projects where the results has been firmly checked the results has been the same

FAQ

Delivery

Question:
What products can you deliver?

Answer:
Our normally deliveries are:

  • Raw LiDAR data
  • Classified laser points
  • DTM (grid or model key points)
  • DSM (Digital surface model)
  • Contour line maps
  • Ortho photos / Ortho mosaic
  • Vectorized maps
  • 3D models
  • Volume calculation

We deliver a wide range of products, so if you did not find what you were looking for, please ask.

 Question:
How fast can you deliver?

Answer:
Deepening on size of the project we anticipate that the flying will be completed within 1 week from mobilization and that the entire survey will be delivered 5 working days after flying. The concept of LAMS is to bring LIDAR surveying.

Question:
In which format can we get the result?

Answer:

  • Ortho images will be supplied in ecw compressed format.
  • LiDAR points will be supplied in ASCII format.
  • Contours will be supplied in Microstation dgn format.

A number of other formats are available, such as Geotiff for imagery, LAS binary for the laser points and AutoCAD format for the contours. Should these or other formats be required, they must be specified and agreed to on contract award.

Question:
In which system can the survey be delivered?

Answer:
The client provides geoid model and reference point that shall be used in the project.
If geoid model and/or reference point is not provided, data will be delivered in ellipsoidal heights on a navigated basis.
All data will be delivered in the UTM co-ordinate system. The concept of LAMS is to bring LIDAR surveying.
Orthometric heights will be determined via the geoid model used, and fitted to local reference point.
Alternatively the EGM2000 model can be used.

 

Flight planning

Question:
Do your flights depend on the weather?

Answer:
Yes, like all flights are. We cannot operate in rain or in strong wind.
Likewise we must be careful when the heat is too strong.
This means, that we often are limited to the hours after dawn and before sunset. The concept of LAMS is to bring LIDAR surveying.

Question:
What about flight permit?

Answer:
It shall be investigated from project to project. Normally you will find restrictions around airports, military installations and around larger urban areas. It also depends on where in the world you are. We will always make every effort to work around any of these restrictions but sometimes it shows not to be possible.   The concept of LAMS is to bring LIDAR surveying.

 

The survey

Question:
On which projects can you compete traditional survey?

Answer:
It depends on size of the project and where it is, but normally we will be able to compete on projects that will take more than one to two weeks for one surveyor.   The concept of LAMS is to bring LIDAR surveying.

Question:
On which projects can you compete traditional lidar?

Answer:
As with the traditional survey, it depends on size of the project and where it is. The concept of LAMS is to bring LIDAR surveying.
In remote areas you probably do not find any companies doing traditional lidar and it normally is very costly bringing a plane with equipment to the airport near the site. The concept of LAMS is to bring LIDAR surveying.
In developed countries you might have problems getting flight permits over urban areas. This might limit us to rural areas for jobs such as gravel pits, survey of corridors for transmission lines e.g. power lines, district heating, water supply etc.
