Hi Trisan

 

I do not agree 100% with your points.

I have seen LiDAR system that are base on VLP16 which is a $8000 sensor, addition of GNSS and IMU and other few integration aspects suddenly the whole thing becomes 10 times more expensive? It is typical of technology, when something new comes out, it usually overpriced at the beginning.

 

With rights to flight altitude, I'm not sure which country you are referring. But if you are from the US the FAA provides 500feet AGL as maximum flight altitude, so the 300 feet you are referring to is not really an advantage as you have tried to put. Because there are many cases when I have does my flight in remote places in Africa and I made justification to fly up to 1200feet and it always been accepted because it is unknown in those remote places there is almost no air traffic and if there would nothing would be flying anything below 10k feet. In situations like this I would not be able to take advantage of that.

 

Thanks

Hi IronDome,

I agree that lidar systems are expensive. However it not only includes the scanner, but also high grade GNSS and IMU, and software to get accurate survey a few minutes after flight.

Flying as high is possible is efficient to cover larger areas, but at the same time UAV regulation often limits the flying altitude to 100m, line of sight, which is suited for small sensors.

All the best,

People know about the LiDAR units yours and others. The main problem is the cost. It at the moment really hard to justify the investment especially for most of us who are small businesses. For large corporations, it may not be a problem.

I have looked at many different LiDAR sensor options nothing is below 75kUSD. The cheaper once have smaller range 50 to 100m, which makes it not cost effective as you have to fly pretty low, so covering large areas can be challenging.

Thanks

Hi,

We are producing Lidar mapping payloads (< 2 kg) since a few years.

Big advantage compare to photogrammetry is that it can see and map the ground below vegetation.

Has anyone been able to get vector layers or markers from a mapbox map to actually display on your mapbox map in tower? 

I have a mapbox project with raster layers that DO display over the top of the basemap, but any markers or .kml, .shp files will not display in tower, but they will display in the browser. 

Pretty damn frustrating.

put an ROI as the first point, at the center of the building, then use the wp circle like you already did

i want to map this building how can i make the front of the multi rotor face inward to capture images of the building ?

Comment by Justin H. on December 3, 2015 at 9:28am

Captured well over 200 acres of usable data on this one.

Gimbal,

I have a 2013 3drobotics quad, does anybody have a gimbal mounted on one of these. I would like to mount a gimbal I can use a canon 260 for video
