Cadastral mapping in its simplest form is adding a database to a lot polygon. You do not want to manipulate database entries from within Civil3d or ev...
Overkill for cadastral parcel mapping
Office practice is to REPRINT maps even with single letter grammar errors. The paper & ink cost less than what the clients will think of your wron...
can it still process baselines after the latest gps rollover?
@stlsurveyor No need to go back 9 years. Any survey grade Lidar manufacturer's spec sheet would tell you that they have multiple returns.
@stlsurveyor You are referring to a paper that was published way back in 2010 or so based on referenced material?
@john-putnam I did not know that there were any differences between aerial & terrestrial. I thought it was the same laser system and the only diff...
They do. The 2nd or last signal bounce would be for the bare earth. If it's not pitch black in the bushes then lidar can penetrate it.
Accuracy Laser accurate to ?ñ 30mm / ?ñ 1.2in ?ÿ May be good for terrain/ground survey but when you need to get man made structures then using those s...
I saw some ads that the latest receivers can receive 440 multi constellation channels (whatever that means). So when they made a demo at one of the su...
There lies the dilemma . Are there any deviation values or accuracy readings from the tilt sensors included in the position files to show an error cir...

If you are not fussy about the brand, then try to look at a japanese brand like topcon or sokkia (now under topcon). They are no frills-get the job do...
My concern is how accurate is the MEMS in translating the tilt to ground coordinates? If an upright receiver would give you 5mm+1ppm. Would the slant ...
RS+ is an L1 only receiver. I purchased an RS2 which is their L1/L2/L5(Galileo E5 only)?ÿ version. Works fine and they offer a free android/Ios contro...

@jim-frame Those are post processed GPS information. We were talking about differential leveling not GPS derived orthometric elevation values.
How would future users have access to these LSA notes? All you are given for a certain benchmark is the elevation of the point. I doubt it very much i...
So using the longer line would result in a difference/error in elevation of 3mm. I would then want to know why you would want to go through LSA when 3...
