Knock out Aerial Drone and super tough SU Challenge
-
The DJI Inspire 1 is next on my list. I'm VERY jealous!!
I'm currently flying the Parrot Bebop.....so much fun!
But that DJI is another league! And awesome work by the way, I can't really help with your question though....

you need to look at other softwares. I tried once with blender when I used 123D scan to scan treestumps and wanted to make low-poly versions of the highpoly scans. It works quite well. I think I used the decimate modifier for that.
Search for softwares that enable high-poly to low-poly workflow, maybe there are some automated workflows for this. In sketchup I don't think there is.

Try Simplygon it's impressive...

I managed to get it down to ~6000 faces
It's texture is 16k x 16k which contributes to the mammoth file sizes you speak of.
Managing texel density can dramatically lower things...
...but polycrunching to get this into SU does mean you'll need to sacrifice something along the way.

Wow, Rich, how did you manage to do that? Is it the simplygon?
The 1 big texture I don't mind.it gives good resolution to the whole thing. In fact that half a gig model was moving and shading pretty quick. Where it was really bugging down is when I try to touch the mesh.
JQL , simplygon looks like what I need. Will have to mess with it tomorrow.
Dbalex, I think you are right, the solution lies outside of Sketchup.
Oli, it is so much fun, it should be forbidden. I still can't believe I own it and there is no price for me to go use it any time. You will be happy. -
Nice project!
Maby you can find some hint in this basecamp video?
-
Richard, Just opened your model. Wow. It answers my prayers. It is exactly what I need. How did you do it?

If you´re searching for a free option you can use blender, this tutorial can help bake the texture from the hi poly model to the simplified one, as a advantage you can even break down some parts of your model and set the texture quality accordingly in that part.

Wow! The Inspire 1 looks to be a great piece of kit. http://www.dji.com/product/inspire-1/feature Easy to operate and yet powerful results and to my surprise at a reasonable price which is sub $3,000 via dealers. http://www.bhphotovideo.com/c/product/1097099-REG/dji_inspire_1.html
I like the ability of being able the attach an iPhone 6 etc or various iPads. I imagine this will make flying much easier for the novice.
I imagine a low set-up cost business could be built on such a device producing aerial surveys resulting (with some extra work) in accurate 3D land models. It could be a great way of bringing down the cost of preliminary concept costing. -
Rich, Mike, It worked!!! I couldnt calm down for hours after the 400+ Mb model became 40 Mb without texture sucrafice!
Now it is a proven workable workflow with manageble and predictable results.Wellcome to the future.

Forgive me but...workflow for what?....and can you show us the result?
When you spend your entire modeling career fighting with heavy terrain and someone comes along with a drone that is part of the solution...seems like too much fun to me.

There is also a workflow for the less expensive Parrot Bebop:
Nowhere near as advanced as the DJI Inspire 1 but similar results and more than 5 times cheaper. I am not even trying to compare them as the DJI is a different league, but if you want "cheap" 3D terrain mapping then the Bebop is pretty awesome.

They also used drones to 3D map the Matterhorn in Switzerland:

This is incredible. Years ago I was following the blog of a kite photographer who worked with a research team at University of California to map one tower and it seemed so cool, and also so far away from being something that others would be able to do.

This is great, didn't think anyone else has been doing this. I've been flying the DJI Phantom 2 Vision + along with Pix4Dmapper for about 10 months. I have access to Trimble GPS and robotic total station so my models are georeferenced but I've been able to do some comparisons also and it's surprising how accurate this workflow is. I have point clouds created this way with Pix4Dmapper that are within a couple tenths horizontally and vertically of survey grade and can cover a much larger area in about a quarter of the time (including processing time in Pix4Dmapper) than an actual field survey . Below a screen shot from Pix4Dmapper of a recent flight.
Ps
By georeferenced I mean to State Plane grid as it's already georeferenced from the photo gps tagsMike

Roland - Here is the resulting SKP Model. Let say if the work flow is polished up from the time you step out of the office to take pictures (minus travel time) to the moment you get model like that is 2 -3 hours safe.

I really must stop reading this thread before my bank account takes a hit.

I must just be dumb cause I still have no clue what the workflow is for.
I see the cool image but it's resolve is very poor.
"workflow"? sure you didn't just mean "playflow"
-
Roland, I don't have the model with me now, but it is pretty similar to what Rich posted.
Can you be more specific about what you are looking for? Witch piece of the puzzle are you missing?
