I can’t get any recognizable results by importing any of the ELEVEN download options provided by a website (Propeller.com) that hosts drone-survey data for commercial clients in support of their customers. Listed downloads are as follow:
3D model (51.6 MB)
DEM (WGS84) 18.59 MB
Contours (WGS84) 525.31 KB
Ortho TIF (WGS84) 279.77 MB
LAZ (WGS84) 89.71 MB
LAZ (UTM) 89.71 MB
Ortho JPG (WGS84) 21.25 MB
Ortho JPG (Small - WGS84) 4.65 MB
DXF (Large 500k - WGS84) 16.83 MB
DXF (Medium WGS84) 8.70 MB
DXF (Small - WGS84) 3.59 MB)
At minimum, I’d hoped to import contours as 3D, then do some editing in SU to clean them up and limit their footprint to my property, but I can’t even get THAT far.
In my dreams, I’d import the full model, find that it’s got contours and other imagery info in separate layers, but at this point, I’m miles from that, it seems.
I’ve tried three times to import the 3D model (51.6 MB), and after 15 minutes or more of autoCAD-entity processing (“merging entities…”), I get what might be a series of line-segments splattered along the blue axis - useless.
Importing the DEM file is suspect from the get-go because it downloads to my PC as an image file (JPG). It opens as a 2D shaded rendering of my contours - as if I’ve imported a flat scan, etc.
I’ve also repeatedly tried to import Contours. It extracts from download oddly, as if it’s an image file that my photo-viewer would open, but with a dxf extension. If anything results from that import, it’s again all stuck to the blue axis and utterly useless.
The “DXF (Large…)” file gets to 99% in the Sketchup import process, then either hangs or moves so slowly that I’d have to rely on my kids to take over where I left off.
LAZ (UTM) doesn’t seem to appear as an import-friendly file type in SU.
The Propeller website support is pretty good, but they seem to be unfamiliar with Sketchup, so it’s up to me to try to bridge the gap. There was vague second-hand info that came from them thru my drone guy, questioning whether SU would require me to use a WGS84 vs UTM setting, but to my knowledge I have no control over that - true?
Thanks - Dave
