Other filtering approaches using MeshLab again but this time doing Vertex Clustering Decimation. SU edges 25625,16900 faces and file size 2599K. The filters it includes are some developers have incorporated in their apps. .Vertex Clustering Decimation.jpg[/attachment]
IMO trying to take this model and editing is not the way to go based on the goal of your OP. To create a virtual tour you must get to the point of selective editing only portions of the map along the lines bjornkn discusses This can be in the decimation or interpolation sense
Next step, layers and selective edits?Those results look quite promising and seem to retain much of the fine detail.
I completely agree about only editing certain portions along the line. Given the sample I uploaded, a true sense of perspective is lost. Here is a set of 3 meter contours for the entire area involved. I would upload the full resolution version but the file size exceeds the attachment limits. The small patch I uploaded is located near the lower portion of the midpoint. See attachment:

Got that in a DEM file? or even .obj, dxf.

Yes. I am actually using a DEM file as the source for the sample DXF I uploaded.

If you can upload it, or part of it, I'd like to try something with Terragen.

I tried uploading it earlier and it was rejected because the file was too large.

Got a dropbox account? they are free, safe and private.

No but I can get one. Where do you reccommend?

@solo said:
I'll go create an account now. What format do you prefer the data to be in? I am currently extracting it to a DXF mesh, is that ok?
-
Sure, or even DEM.

The DXF mesh extract was huge and is still uploading to my dropbox but the DEM extract was surprisingly small. See attached:

You may want to check the dem file, it's kinda wierd, hard to explain, lacks all detail.

I looked at it and see what you mean. I must have inadvertently selected the wrong scale when I exported it. The DXF file just finished uploading, here is the link:

750MB file.
gonna try open in SU first, see if flames spew out from CPU. -

750MB file. gonna try open in SU first, see if flames spew out from CPU.See why I wanna reduce it? LOL

I doubt very highly that you can reduce that to a point it opens in SU and resembles anything close to what you need, but lets try, I have all sorts of tools to try with.
I'm trying Vue-SU first, but that will take a while to import.

I do too but was going to divide it into several sections as to lighten the load of each.

If I can figure out why my 90% reduction in Deep Explorer isn't coming out like yours, I believe my problem may be solved. I have tried numerous variations of settings but I start to lose detail at around 50% and it gets worse from there. I even managed to make what resembled a spiked cactus once.

What is GP?
Guide point.
I suppose you not knowing that implies that you never tried the method at all, but just were thinking that it would be way too much work - even just to try it? -

Remember, I'm not a Sketchup expert, or an expert with 3D software in general, far from it in fact. By and large, I am learning as I go and will undoubtedly make a lot of mistakes along the way.
Honestly, and I am showing my ignorance here, but I am not completely sure what the guide point method entails. If you would care to enlighten me, I'd be happy to give it a try.
