Advances in 3D data capture are changing faster than ever. How can we help you in 2013?

First, let me say Happy New Year to all of our clients who have supported us for the past 25 years. We appreciate you and are honored that you choose LandAir Surveying to team with you on many interesting projects across America.

Over the past seven years of traveling down the road of 3D data capture and using multiple platforms for LiDAR data collection, we have seen this technology expand into almost every field of design, construction and manufacturing.

It has been fascinating to watch the world change from 2D plans to 3D data sets and models. And in the process, modeling is becoming cheaper, faster and easier.

Having attended international conferences and through speaking to groups across the country, we have seen and studied with interest what is going on in the U.S., Europe, Japan, India and Asia. The whole world of design and construction is making this shift!

Daily, we talk with firms both domestically and internationally about the diverse issues of 3D design and construction to equip us with the knowledge we need to be your trusted resource for new approaches to surveying projects.

For example, we have been producing surveys for the transportation industry since 1998. I can remember when we had to actually put our surveyors out in traffic (with approved safety measures, of course). Now, with our scanners, we can stay off the shoulder of the road and capture all the required data without putting anyone in harm’s way. This is standard practice now and, as an owner of a surveying company, very important to me personally.

Approaches to projects are changing not only in transportation, but across all industries.

Last year, we produced a 400-acre topographic map with 1-inch contours in very, very dense foliage. Just two years ago, we would have had to field survey this project. But by using a combination of aerial LiDAR and strategic surveying techniques, we were able to produce the job at 1/3 the cost of a traditional field run survey.

In 2013, we plan to expand our technology, using drones to capture data on specific projects. This is already being done across the country and the technology is moving from military grade and unaffordable to civilian grade and absolutely affordable.

So, how can we help you this year? For one, we can show you how surveying tools are changing and getting better. We can discuss with you when to use airborne LiDAR to document and produce data over a city, county or state.

We can show you when the conditions are right to use mobile LiDAR and put together a team to make your project successful.

We know when to use helicopter platforms for LiDAR over fixed wing aircraft, and we can show you how to model the inside of an existing building faster and more cost effectively than ever before.

We look forward to being a valuable resource for your firm and hope to continue working with you in 2013 and beyond. The design world is changing very fast and we are committed to changing right along with it.

Have a great and profitable 2013!

What’s all the fuss about high definition scanning?

/0 Comments/in /by

When it comes to making precise measurements in complicated environments, high definition scanning – or 3D laser surveying, as it is sometimes called – is quickly making its way to the front of the line in a wide range of industries from engineering to historic preservation.

Engineers use laser scans to work with real-world conditions in complex industrial as-built and plant environments. Construction companies use them to gather precise data on site terrain and renovations, and architects use them to check proposed design models against existing conditions to fine-tune their designs.

Even insurance companies and law enforcement have gotten on board, utilizing the technology to recreate large-scale accident scenes.

Why is it better? For one, laser scans are incredibly precise. Images are created from a “point cloud” of millions of points that can be measured precisely including the distances and elevations between points. They are also versatile. The scans, when used with digital color photos, can produce survey-quality files, videos or even 3D animated computer models and are so intuitive that even a novice can understand the information.

Laser scans are also fast. In 2006, when we bought our first scanner, it took almost an hour to produce a full dome 360 degree scan. Now we can scan in 6-8 minutes. This allows us to take many more scans and capture more detail than we did before.

Scanning almost always pays for itself. It is cheaper in the long run because you can revisit the original scan multiple times from your computer desktop without having to revisit the project site. Also, because the technology is so precise, the need for construction reworks and expensive retrofitting is minimized or removed alltogether.

For firms thinking about getting involved with this technology, there are currently three ways to capture 3D data on large scale projects: Airborne LiDAR (Light Detection And Ranging), Mobile LiDAR, and Terrestrial Scanners, which all produce LiDAR data.

Typical projects for terrestrial scanners are large pipes and tunnels, manufacturing facilities, plant process facilities, airport conveyor systems, bridges, buildings, towers and construction projects. (Our firm focuses on terrestrial jobs, as most cannot be readily scanned from airplanes or cars.)

The cost of entry into this kind of scanning is generally between $150,000 to $250,000 for the first units and software. (Although less expensive scanners are now available, software packages can still be expensive and the cost of training should also be considered.)

Aerial platforms and Mobile Platforms start at $500,000 and go up to $5,000,000. These units are constantly being upgraded with newer and better digital sensors and data management enhancements. We currently work with service contractors on these types of jobs, which are typically focused on documenting civil infrastructure on a much larger scale than terrestrial scans.

Projects could include scanning 100 miles of road to prepare a pavement analysis, mapping 1,000 miles of rail line, or mapping the City of Atlanta and producing 3D models of all the buildings.

If the cost of these units seems intimidating, keep in mind that firms that have already invested in these technologies are often open to partnering opportunities with smaller firms.

Small scanning focuses on objects the size of a Volkswagen all the way down to the mechanical components inside of a watch. The applications in this field – commonly referred to as “reverse engineering” – include quality control of manufactured parts or data capture for a manufactured process. A typical project could be scanning an ornate stair rail so that an exact replica can be created from wood, metal or composite.

This scanning method is so precise that you could dissemble a toaster, rifle or carburetor, scan the parts, manufacture duplicates, and they would all work when re-assembled.

What can be scanned?

If it can be built, it can be scanned. There is virtually nothing built that cannot be duplicated and modeled with current scanning techniques.

In addition to the engineering, construction and manufacturing industries, this technology is also being used by insurance companies and law enforcement to reconstruct accident scenes – like when a highway bridge falls during rush-hour traffic or a multi-car pile-up – and even on Hollywood sets. There are companies that make their living scanning elaborate movie sets before and after they are constructed.

To give you an idea of the wide-ranging capabilities of this technology, in the last month, we have scanned a 120-foot pipe in Chicago, a 737 aircraft in Delaware, a luggage system in LaGuardia, and the interior of a peppermill in Virginia. This technology is everywhere!
