    It's accurate.  But accuracy is a relative term.  Question is, is it accurate "enough"??  Followed by "accurate enough for what"?? 

    Why use it??  Lots of reasons to use it.  Lots of reasons not to use it.  All depends on the project. 

    One reason to use it: 

    I have had many occasions on remote projects, that is, projects that are hudnreds or thousands of miles away from the office, and the engineers/architects almost always ask for items outside of the original survey limits.  Having "over-scanned" these areas, their items of interest were able to be extracted from the point cloud data without having to incur those budget-busting return trips.  And we were able to charge for the value of the data, as opposed to the additonal costs of the return trip.

    One reason not to use it:

    Overkill.  If you're measuring bridge clearances (only) say, then take the reflectorless total station and shoot 2-4 points and be done.

    For me, it is another tool in the tool box.  Some projects, there's no other tool that can do the job.  For other projects, leave it in the tool box.  It definitely has it's role, and we are using all three: static, mobile, and aerial LiDAR.  And with the increasing trend of designing in the 3-D world, it will be here to stay.  For layperons, it's a "wow" factor when providing them with the free viewing software that goes along with several of the scanning providers.

    My 2 cents...--JTH

How to Utilize Surveyor Forums

How to use Forums
Our forums on Land Surveyors United are here to be used as much for finding help with problems in the field as the are for you to express your opinions on anything that has to do with land surveying in general. Feel free to share anything that is on your mind, as long as it isn't meant to damage another member's reputation. Please keep it clean and help insure that everyone has the opportunity to enjoy the benefits of being part of a community that grows together.

We are committed to allowing freedom of expression for all of our members, and that includes maintaining a safe space for people with opposing views to express themselves. We get posts from all over the country and even the globe, so needless to say, people come with different viewpoints on lad surveying practices and processes. We see this diversity and variety as a real strength-- dialogue and debate are an integral part of the educational process, as well as an important tool in exploring different sides of complex issues.

All Community Hubs inside the community have their own forum for asking specific questions to other surveyors, by location, equipment type, etc.
