How will Augmented Reality Evolve
Land Surveying?
By Ryan Waters and Patrick Engle, GdB Geospatial
Being able to view data on a map is one thing. Being able to visualize this
data in the field is another - and the developing field of augmented reality

is attempting to accomplish just that. Augmented reality, as we think of it
today, has been around since the early 1990s. Once viewed as a novelty,
June 7 - Saratoga it has been gaining serious traction through practical applications that
(Saratoga Spa State Park) enhance how we view infrastructure assets.
One such application is full Reality Capture. By scanning or photographing
assets we can develop 3D models of assets or infrastructure. Modeling
has given AEC professionals the ability to review objects or plans while
not on site. Full sites can be vectorized and attributes applied, so review
can happen in the office - saving time and money. Additionally, multiple
captures can be taken over the course of a job, creating a time lapse of
what tasks were completed and document when they were completed. As
the technology grows, we have wondered how can we leverage this data
for future work, once the assets have been buried or sealed?

collection, modeling and georeferencing of assets can be captured as they
June 9 - Putnam County are being installed. Currently, we have used the technology for capturing
(Fahnestock State Park) underground utility assets that are exposed in an open trench. We then
produce a georeferenced model that can be reviewed on site later. Bulky
equipment, like headsets and projectors, or having super powers to see
under the asphalt is no longer required, just a person with a smartphone
and an app. By walking over a previously dug trench and looking through
a phone or tablet using augment reality software like vGIS you can view
the assets as if the trench had never been filled. Additional information
linked to the asset can be viewed on site with just a click, such as weld
ID’s or schematic drawings.
Current phone location data is not as accurate enough on its own so
some additional spatial correction must be applied to situate the user.

the use of an RTK antenna to enhance your spatial location is necessary
to be able to view this information effectively. As the technology and
software continue to make leaps and bounds, surveyors should continue
to be on the leading edge - not only to provide the best product for their
clients, but also to continue pushing the profession forward.
