Dunwoody Surveying students place 1st in 2016 NSPS Student Competition

Second-year students Wyatt Spencer, BJ Klenke, Doug Pouliot, Joe Irey, Brandon Davis, Jake Blue and team observer Patrick Kowal took first place in the two-year degree program category of the 2016 National Society of Professional Surveyors (NSPS) Student Competition earlier this month.

The annual event—which was held in conjunction with the 2016 Surveying & Mapping Conference—was held in Crystal City (Arlington), VA, and was open to all two- and four-year colleges across the country.

New event, new skills

To enter the competition, the Dunwoody team—advised by Surveying & Civil Engineering Technology Principal Instructor Kelly Ness—had to complete a boundary and topographic survey of a parcel of land, approximately 10 acres in size, for a hypothetical land development project.

The team was then required to create a “metes and bounds legal description” of the land lot (i.e., a description of the land and its boundaries) and construct a plot map of the surveyed area.

This information—along with a safety plan, field notes and data calculations—was compiled into a final project binder and then presented to a panel of industry experts and competition judges.

“In order to complete the project, we had to develop the types of skills that are used everyday in the industry,” Ness said. “That was the most beneficial piece for the students—the knowledge and skills obtained throughout the competition.”

A welcome win

A first-time event for Dunwoody and the students, Ness said he couldn’t be more pleased with the outcome.

“Winning the competition is a huge achievement and one that will be recognized by future employers and peers in the surveying community.”

Spencer, Klenke, Irey, Davis, and Blue will graduate with an associate’s degree in Surveying & Civil Engineering Technology this May. Pouliot will follow in Fall 2016. Kowal hopes to participate in the 2017 NSPS Student Competition next Spring.

The College would like to thank industry partner Westwood Professional Services for their generous donation, which allowed the students to travel toand participate inthe competition.

Surveying & Civil Engineering Technology students calculate circumference of earth using ancient and modern methods

 

Second-semester students Wyatt Spencer, Jake Blue, Jeremy Brunell, Joe Irey, BJ Klenke and Brandon Davis calculated the circumference of earth using ancient and modern methods.

Second-semester students Wyatt Spencer, Jake Blue, Jeremy Brunell, Joe Irey, BJ Klenke and Brandon Davis calculated the circumference of earth using ancient and modern methods.

After studying Greek astronomer Eratosthenes’ methods to calculate the circumference of the earth, students in the Geodetic & Controls Surveys class recreated the process using ancient–276 BC–methods and modern technology.

Second-semester students Wyatt Spencer, Jake Blue, Jeremy Brunell, Joe Irey, BJ Klenke and Brandon Davis gathered background information about Eratosthenes from the book “Elementary Surveying: An Introduction to Geomatics (13th Edition).”According to their research: Eratosthenes determined on the summer solstice each year that the sun was directly overhead the city of Syene, Egypt. It was noted that while looking down a particular well, one could observe the sun’s reflection was directly in the middle of the water. He lived in Northern Egypt, in the city of Alexandria, which was 5000 stadia (equal to 500 statute miles) from Syene. In the city of Alexandria on the summer solstice, he then measured the length of the shadow created by a tower in the city of Alexandria. Using simple geometry he calculated the angle between the tower and the shadow, and determined the angle to be approximately 7.2 degrees, which is one-fiftieth of a circle. Eratosthenes then had the distance between Alexandria and Syene measured by averaging the time it took camels to travel the distance between the two cities. He took that measurement and multiplied it by fifty to approximate the circumference of the earth. His result was remarkably accurate, differing from a commonly accepted value (24,901) by less than 100 miles.

Since the sun was not directly over the Dunwoody campus and it wasn’t plausible to drive the 500 miles to carry out the measurements, the class reached out to a forum called surveyconnect.com to ask for a volunteer to assist them in measuring the angle of the sun’s rays. Dan Robinson, of Little Rock, Ark. responded to the students’ request for assistance.

On January 16 at approximately solar noon, the students went outside in front of campus with a 24-foot pole—which they made by connecting six four-foot range poles. They held the pole vertically and used a plumb bob to confirm it was vertical. They then used a 100-foot tape measure to determine the length of the shadow cast by the range pole.

They measured a shadow at 59.9 feet from the base of the pole to the tip of the shadow. At approximately the same time—solar noon in Little Rock, Ark.—Robinson measured the shadow of 39.6 feet from a 25-foot pole.

“Dan’s participation was greatly appreciated,” said Principal Instructor Kelly Ness. “I think it speaks for the support students have from others in the surveying community.”

Using the coordinates Robinson gave them for his location (N 44-35-00 W 93-10-00), the coordinates of Dunwoody College (N44-58-22 W93-17-28) and a program to convert coordinates to geodetic distance (http://www.movable-type.co.uk/scripts/latlong.html) the students determined the distance between the College and Dan’s location to be 706.49 miles. With this information they were able to calculate a circumference of 24,383 miles. The value they calculated is similar to a currently accepted value of the earth’s circumference at the equator of 24,901 miles.

Although they enjoy the modern day GPS (GNSS) technology they’re using in their classes, the students are interested in additional projects using ancient methods of measurement.

“Next we will create a triangulation network similar to the method used from the late 1700s through the 1900s,” said Ness. “Surveying is a profession that will forever be tied to the past.”

RDO Integrated Controls supplies Topcon equipment to Surveying & Civil Engineering Technology Program

Dunwoody’s Surveying & Civil Engineering Technology students are using state-of-the-art Topcon equipment thanks to RDO Integrated Controls.

Dunwoody’s Surveying & Civil Engineering Technology students are using state-of-the-art Topcon equipment thanks to RDO Integrated Controls.

RDO Integrated Controls provided the program with four Topcon HiPer SR GNSS receivers and Telsa data collectors with Magnet software at a low cost rental for the school year.  The HiPer SR is a Global Navigation Satellite System (GNSS) used to measure and layout precise locations on the ground.

“The previous equipment was older technology–strictly GPS–and was not utilizing all of the satellites that are available,” said Surveying & Civil Engineering Technology Principal Instructor Kelly Ness. “Now the students are using the latest industry standard equipment.”

RDO Integrated Controls provided the Surveying & Civil Engineering program with four Topcon HiPer SR GNSS receivers and Telsa data collectors with Magnet software at a low cost rental for the school year.

The HiPer SR is able to connect to a network of base Virtual Reference Stations (VRS) that the Minnesota Department of Transportation maintains.  The VRS enables students to achieve centimeter level positioning without a local base station.

Ness said industry partnerships and donations are appreciated and ensure that graduates are familiar with the newest industry technology when they enter the surveying and civil engineering workforce.

Surveying & Civil Engineering Technology now offered during the day

Starting in August 2014 Surveying & Civil Engineering Technology will be offered as a daytime program at Dunwoody College.

The program has been offered at Dunwoody since the early 1920s, but starting in 2001 classes only became available in the evenings.

Surveying & Civil Engineering Technology Principal Instructor Kelly Ness says the switch to days will result in larger class sizes. He says evening programs tend to attract smaller classes generally made up of non-typical students who are changing careers.

“We would like to have full classes of graduates,” Ness said. “We feel the switch to daytime classes is necessary to attract the number of students that the industry will need in the years to come.”

The switch to daytime classes isn’t the only change for the program.

“We are in the process of introducing an updated curriculum to keep up with an industry that is constantly in flux,” Ness said. “There is new equipment on the doorstep–imaging, laser scanning and unmanned vehicles–that will revolutionize the industry. We need to be ready to integrate these technologies into the curriculum when they become adopted by the industry.”

Ness says many of Minnesota’s licensed surveyors have graduated from Dunwoody. He’s confident the recent changes to Dunwoody’s program will ensure employers continue to have plenty of quality civil engineering technicians available for hire after graduation.
