Scanning
the Trends
February 2010
It’s really not the Point of
Beginning.
My grandfather was born in Sweden
in the late 1800s. At 19, he traveled to America
through Ellis Island, first settling in Michigan
then on to Idaho
and then the West Coast. By midlife, and married to my grandmother, he was a
blacksmith with 13 children. The family got by, but many changes occurred
during their lives. Pounding out horseshoes, hinges, nails and wagon wheels
eventual gave way to rubber tires, industrial machines and modern
manufacturing. Blacksmiths were forced to either retire or become
millwrights.
Land surveying is in the midst of experiencing the same dilemma. The cover and
articles in the February [issue of] POB bring to light the latest trends in
surveying. Each new article defines how land surveyors will collect and
distribute data. I estimate that within the next few years, SUV-mounted
scanners will give way to satellite “real-time” topographic mapping and photographic
cameras that will “watch the grass grow.”
We will be able to count the orange buds in Florida, track the location of all
bee hives and even count the bees and numbers of pollinated flowers. This
technology is here to stay, whether we like it or not.
Like my grandfather, we, as land surveyors, will need to decide how to proceed.
Some will follow the road of photographs and scanning. We will buy bigger and
better trucks and better “cameras.” We may add “mag” wheels and oversize tires
or even buy a used unmanned military “drone” and outfit it with the latest
gear. POB may continue the trend and write and research articles showing the
latest and greatest technology winner.
Although my other passion is photography and the outdoors, I chose to be a land
(boundary) surveyor. For those of us that do not follow the path of
“photography,” we will need to understand the roots of land (boundary)
surveying. The basics used by surveyors before us might even save us. Their understanding
of boundary lines, property corners, mathematics, evidence, control surveys,
land title rights, measurement, and even error is crucial and everlasting. No
camera or scanner will be able to compete with rational analysis, original
monuments, closing corners, senior rights, gaps, gores and, of course, digging
up those old pipes and stones.
I think it is time when we as land surveyors and POB must decide if the
magazine is truly the Point Of Beginning or is it just another Photography Of
Beauty, which does have the same initials.
Oh, by the way, my grandfather retired.

Points

The ACSM definition of land surveying is the science and art of making all
essential measurements to
determine the relative position of points and/or physical and cultural details
above, on, or beneath the surface of the Earth, and to depict them in a usable
form, or to establish the position of points and/or details.
I’ve been in the land surveying profession for many years, and the only thing I
believe I do is measure. I
use tools to do this measurement,
and these have changed from time to time, but their purpose is still to
measure. That will never change no matter what some will say. When the time
comes to prove what was done, our records of how we measured will be the prima facie evidence.
I’ve written a couple of pieces for POB over the years. The most recent was titled “Surveyors
in Turmoil” [Web Exclusive, Aug. 26, 2003, online at www.pobonline.com].
I took a look into the future and saw the surveyor getting away from measuring. We, the surveyors, have allowed too many
situations pass by us. As your editorial pointed out, will we be ready for the
‘e-revolution’? Are we truly getting away from measuring?
