What a simple orthomosaic and DEM can do


Using Orthomosaic and Digital Elevation Model to create 3 D model is nothing new. But normally it will require lots of computing power and knowledge. Skyline's TerraBuilder and TerraExplorer make it easy for the average people to make 3D video from an orthomosaic and DEM. For sure there are lot's of other functions within the software, I think just a 3D fly around video create by my recent aerial mapping work will enable my client understand his land better as he can view the area at difference angle and prospective.

I just learn some very basic function and will need proper training to fully utilised the powerful software. I find very limited resource in the net to help the learning process. Any idea ?

Stunning results and great quality of this 3D tour, Keeyen.

This looks great. Did you use TerraBuilder for the whole process? I have been looking for something simple to create 3D videos of DEMs.

Thanks, Ecosrones. Hi Dan Murray, you'll also need TerraExplorer
Comment by Waladi on September 17, 2014 at 6:54am
That is Very large area that you map, do you mind to share the spec of airframe, camera, speed of flight, duration, etc?
Sorry for OOT question, great video!!

Looks great,but how much does this software cost?

Comment by Gil Rosenthal on September 17, 2014 at 11:22am

Hey Keeyen,

Looking great - That looks like the Photomesh/Acute3D module. Is it?

(if it is = mucho $$$!)

Want to second Waladi - what setup did you use?

Comment by keeyen pang on September 17, 2014 at 4:41pm

Hi Waladi and Phil Gordon

The area is about 600 Ha. My equipment is FX 79 with APM. More info here and also here. I'm using Canon S100 GPS with CHDK. Flight speed is about 60 KM/H on average. Total flight time is 50 minutes. I'm using Terrabuilder and TerraExplorer. I'm still waiting for my local reseller to confirm the price. This is a " trial " copy

Hi Keeyen,

Amazing setup... do you map all 600 Ha on single flight mission? What is your Altitude setting? 

Since I'm very bad pilot and cannot land a plane so with similar purpose, I'm building different endurance quadcopter to achieve > 40min flight and with the same speed of 15 m/s (54 Km/h)  and carrying Sony Nex 5N with flat map 2 Axis gimbal.

Attached is the spec and calculation, if you may look in to it and give feedback, I will very much appreciate it.

How do you feel about the picture result from S100?

I get almost 50% blurry image due to its floating lens.

Waladi, I am not Keeyen, but if I may: it may be worth your time to try and learn how to fly planes. I was in the same boat as you and ended up buying a PC simulator as well as a trainer plane, and got it down in no time. I'm glad I did. For aerial survey, planes are much, much more efficient.

Also, the S100 is a good camera, so long as you tune your exposure settings well.

I do agree with Dan Murray. The multi rotor you are looking at has yet to prove itself to fly in windy condition. It is also expensive at this moment.
Only one flight to cover the whole area. 300 meter altitude.
My Canon S100 setting. TV. 1/1600 shutter speed. Auto ISO. WB: Cloudy. Manual focus set to infinity. Switch off IS. I seldom see blur picture when fly at 300 meter altitude. Hope this help.
