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.
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.
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.
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 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.
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.
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.
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.
