I've been getting inundated with the above ad for this measuring device. Looks interesting, but not super precise? I wonder if anyone here had any hands on experience with one. Might have a use??ÿ
Geezers. ?ÿMy 1st time seeing this. Is it like a digital replacement for the old wheel. All the technology coming out has created expert measures every where. As someone who loves surveying most all aspects. All these advancements with imagery and tools like this make it a challenge for surveyors if we don??t keep preaching the gospel so to speak and educate the public. We have to police our own as much as the public now days for sure. ?ÿ
If you can suffer through 25 minutes of amateur video taken by someone who's not the sharpest knife in the drawer, you can get a look at some of the real-world issues with this device.?ÿ I'm not convinced it has *no* application to surveying, but the limitations appear to be significant.?ÿ The "must stop to take a reading every 6 seconds" seems like a biggie.
?ÿ
Here's another video, this one by a landscape contractor.?ÿ He first uses Moasure to measure the perimeter of a proposed raised area, and you can see where the device reports a fair number of measurements as having error estimates larger than the warning threshold.?ÿ It force-closes the perimeter and reports a 1.3% error.
He then uses Moasure to check vertical on a retaining wall foundation, blindly accepting the numbers the device spits out.?ÿ After the pour he checks foundation height, and Moasure reported his check points as 1-2 cm from flat, so at least he's getting decent repeatability.?ÿ But again, no independent check.

I have a GPS with the tilt correction function (Leica 18i). It works great but you have to keep moving for it to function. If you stop at a point for 3 epochs you are likely to lose the tilt correction. It really needs to be used with instantaneous recording. I'm guessing that this Moasure device has similar issues.?ÿ ?ÿ
These guys go to big trade shows, but don't list a phone number, don't have an address, I am not sure if I even know what the company name is. I believe that they are actually named '3D Technology' and are out of Warwick, Warwickshire in the UK. But I honestly don't know why they are in my phone or where I ran into them.
I always worry about buying stuff from an outfit that literally does everything possible to hide who they are, where they are, how to contact them and even a phone number. Geeze you can't even send them email, you need to use a web form. Doing a WhoIs returns TUCOWS provider with a privacy masked address.
While I am sure they are not a scam, it seems to me that they have done every single thing possible to look like they are.?ÿ
Firsts generation devices are always terrible and I'd never buy one. I would say this is a sign of things to come, the new technology available in smartphones (and iPhones) will eventually be used to achieve survey grade measurements that any average user can capture. Just look at news of war casualties because of using a connected device on the front lines. The positioning will only get better and by the end of the decade, I would expect major changes to how surveying data is captured (the field surveyor is going to become even more niche).
It's only good for estimating, nothing precise.
Now if it could utilize GNSS RTK in addition, now that would be interesting.

Yup. IPhone 14 Pro Max, iWatch.
- Precision dual-frequency GPS (GPS, GLONASS, Galileo, QZSS, and BeiDou)
Not single-frequency. But dual-frequency GNSS. ; )?ÿ Getting there... just need external antenna for more precision.?ÿ I.e. Pix4D. Emlid, etc.

Lets take a little look at history. In 1807 Fernanden Hessler was appointed and which is now NGS but thats a rough estimate of when our now NGS started. A 1? transit was designed and brought to the United States This is on NGS website and in other history books and some great readings at the naval observatory. Our weights and measures were all a bug start by him. He led the charge for standardization. I know I might be spelling his name wrong so please forgive me. I am being very lazy tonight. That 1? transit was so heavy it was moved with a wagon pulled either by oxen or mules. It was so sensitive it could not be leveled in daylight. ?ÿ1? 1 second. Fast forward a bit through all the devices used to measure invar rods and their predecessors . We today take so much for granted. ?ÿGPS was designed and thought of in the 1950??s easily. I will leave it at that. ?ÿBut through all the advances in technology chains rods steel tapes. Transits theodolites EDM. Satellite measurements vlbi and more imu has been used for navigation for a long long time on naval vessels and ships. Survey grade on smartphones i phones is and has been possible for a while. Its just not been cost effective for the technology to be in for the consumer. Lidar has been around for a long time we are all seeing the fruits of those before us. They planted the seeds nourished the crop and even harvested it for us. We get to enjoy the sweet taste. Lets not forget that. Lets also not forget no matter how well we or our neighbors can measure. That??s only one portion of being a boundary surveyor. Will we have to fight and educate ourselves and the public. ?ÿYes we will if we wish to keep the profession moving forward. Some in our profession risked their lives literally with Indians outlaws and disgruntled land owners. Some in combat zones and some from harsh weather and conditions. Like the hoover damn. Rocky Mountains Swamps of Louisiana and Mississippi. If we can learn those things and educate the public as we move forward we can survive. It will not be easy. Other countries our already moving to coordinates. Not that using coordinates are bad but it is only a result of our measurements. And our measurements are not and never will be perfect. This is what separates us from the tools we use. The tools make it easier and more cost effective (sometimes) But we should not let them take our place. We can perform an accurate boundary survey with a steel tape plumb bob and 20? transit. And we can use gnss or robotic total station that is .5? angular and 1mm distance and have a very i accurate boundary. ?ÿOur measurements might be better but that doesn??t mean the decisions we made were. ?ÿI like technology its fun its a learning curve. But keep everything in perspective. ?ÿI keep waiting on my all in one laser glasses that do high end images and lidar and gnss all at the same time so i can walk all the property and collect everything i see and don??t see lol.?ÿ
It already takes relatively little training to collect points. I'm quite sure that I can take the average willing high schooler and have him/her collecting points within a few hours. Getting them to collect the right points will take months, maybe years of training.?ÿ And arranging those points into a presentable map is a whole 'nother thing.?ÿ?ÿ

All these devices are a real threat to our industry. I think it is a load of crap. I have a 100k instrument where the imu isn't as precise as this one claims to be.
We can only try to explain to people it is just a toy.
It would be nice to have someone with a ts doing a comparison against a total station. Maybe Rami Tamimi could have a go with this.

It's not the devices which are a threat - its those who buy them and misuse them.
The firm is a spin-off from Warwick University. In the UK they appear to be directing their advertising towards landscape gardeners and the like - those who only need dimensions and areas to a few feet. For that purpose the device is probably quite OK. As with everything it is the idiot who comes along and says "I can do anything (especially screw the job up!)" who casues the problems.
