Got a pretty serious topo coming up with lots of buildings and flat work.
The client wants it done to where a 3d model can be done with the info. I will not be doing the model, that is up to someone else.
Question for those of you that have scanning capabilities, what would be the cost of something like this field to finish.
Details.
Maybe 3 acres of a manicured winery business with 7 large buildings, parking lots, some trees,lots of meandering walkways, several outdoor covered areas, tour buses coming in and out all day.
The buildings and their roof lines need to be located H&Z. They are going to put in an small plane airport at a later date.
Lots and lots of conventional work doing it the old fashioned way. I have enough in the budget to do it conventional, but would like to compare apples to apples.
Since we have been bombarded by scanner stories and ads in certain magazines for years now, anyone willing to give a wild estimate on this using a scanner and also creating the model in ACAD.
Thanks,
Can you email me some pictures?
Sounds like a lot of cash, with multiple set ups,(hopefully there are marks around the property to fix in the scans) part but the processing for all the scanner locations will add up.
There is a large firm here in WA,AUS that charges around $20k a day for field time and then around $300 an hour to process.... But over there in the US i am sure you could probably half that.
Don't know about cost but it takes expensive specialized software to process and use point clouds in AutoCAD.
Scanning is great but sometimes it's faster to just topo it and connect the dots.
It can be tough/impossible to see things like EPs where there is a small color break. Of course it's great for 3D buildings and hard surfaces but remember it only gets what it sees at ground level for surface features. So, for example, if you are on the planter side of the curb it won't get the toe of the curb without another setup on that side. It will pick up hundreds of feet of reflective thermoplastic striping from one setup.
Remember that the dots spread out radially and this is especially dramatic on horizontal surfaces where each concentric row of dots gets even further away due to flat coincidence angles.
We have experimented some with topo'ing with it, it has its pluses and minuses.
Wish that I could get $20k a day. Perhaps you mean $2K a day?
You might spend 15 minutes studying Agisoft, Aerohawk, Datumate 3D or Photo modeler scanner. I have gotten some great results with this new technology. I would also talk to Andrew Walker at QCoherent in Alabama. He has a software called LP360 that can do some really amazing things with the .las files.
I would probably call up a buddy that has an R22 helicopter. Get him to fly back and forth across the area for 30 minutes with a modified 300 dollar Canon camera mounted to the landing gear. Being about 300 feet off the ground the helicopter could fly early in the morning before the crowd got there. If the helicopter guy had a 2 hour minimum, your looking at around 600 bucks. I have a Quadcopter from 3D Robotics that I strap the camera to.
I would shoot in control points at all building corners ground and roof line under the soffet along with the visible corners of the intersections of the sidewalks. Then I would spend the rest of the day taking pictures from the ground in a pattern that will make sense to the software. These software have been developed based on the gaming industry modeling.
I know it is a scary jump for a Professional to use anything that has to do with games, but some of these things can be extremely powerful in the hands of a professional. Do your research on these new technologies.

Is this legal in Texas?
Randy,
Email or call me to discuss. We do all that and more and would love to help you out. We can scan and produce all the 3d models you need, plus even provide them with the point cloud data in a viewer so they can dimension, etc.
Thanks - Matt

The pilot for the R22 is a commercial pilot. It is over private property. Would fall under the same rules of cropdusting.
I have not accepted any funds for flying my quadcopter nor was I on the clock for the time that I was flying it for my personal projects.
I am not a lawyer.
This is an interesting read.
