Mapping railway and meeting deadlines despite dense forest and rough weather

This spring, a small team of surveyors from the Polish firm Usługi Geodezyjne Leszek Kaczkowski had one week to map a 115 km (71 mi) section of railway between Szczytno and Ełk. They were joined by Wingtra dealer, Geotronics Dystrybucja Sp. z o.o. The weather over the project time featured strong winds and rain. And to top it off, 40 km (25 mi) of track ran through dense forest, presenting limited take-off and landing space.

With WingtraOne we surveyed the entire line of track in a week, with just 3 people. If we used classical methods, we’d need 2 or 3 whole teams to work for a month.

WingtraOne’s ability to take off and land precisely in tight spaces offered a lot of flexibility to tackle the job. “The take-off and landing accuracy of WingtraOne was a great advantage,” Stolarski said.

During the project, winds reached up to 8 m/s (18 mph), yet WingtraOne collected all of the data within 2 cm (0.8 in) accuracy.

“The wind was no problem. And with the high-end PPK module, we used reference station data to get high accuracy,” Stolarski said. “Thanks to this setup, we were very mobile and flew efficiently.”

Result? A data-rich survey, on time and to spec, and a couple of highly-impressed companies.
