Karpenisi, Greece, Nov. 26, 2007 – The rugged mountainous highlands of central Greece can be a challenge for even the most skilled surveyor, and as Theodoros Vaxevanos is finding out, choosing the right equipment can make all the difference.
A civil engineer and surveyor since 1993 and a survey business owner in the region since 1996, Vaxevanos recently made an important and productive move: switching from a total station to the Magellan ProMark3 RTK GPS receiver for his stakeouts, cadastral surveys and topographic work.
“I use my new ProMark3 RTK with the Survey or Fast Survey in RTK mode for all my activities that need centimeter-level accuracy,” said Vaxevanos. “When I saw its ability to deliver that accuracy with no problem and at a good competitive price, I knew this was the system for me.”
His survey work covers the spectrum from small topographic diagrams of plots and parcels to topographic studies and surveys for road and construction sites, cadastral surveys for urban studies, geodetic leveling network studies, as well as sewer piping and water supply studies.
JGC, Magellan’s dealer in Athens, came to Karpenisi to demonstrate the recently introduced ProMark3 RTK. “When I heard the price and found that the system had the flexibility to cover all my applications, I purchased it. It’s an easy choice compared to the dual frequency systems that it competes against,” added Vaxevanos.
The equipment Vaxevanos used prior to the ProMark3 RTK was a total station for survey work and an older Magellan 330 handheld for mapping. “I find the Promark3 RTK is a more efficient, easier, and much more cost-effective way to work,” he said. “It provides complete and reliable data for survey and mapping. Comparing it to competing systems, I find it less expensive, and it supports the RTK function and outperforms all other single-frequency systems for accuracy in real time, which is most important in my view. The ProMark3 RTK has the best performance-to-value ratio, and it is the best solution for a surveyor’s everyday work.”

Each month we select a hot topic and a leading figure in the industry to write about it.What message are we sending to senior level decision makers about the importance and value of Spatial Data Infrastructure - SDI - if we keep misrepresenting what SDI is or is all about?
In previous editorials in this magazine I have touched on various SDI issues, especially now that the pan-European SDI has achieved a legally mandated status within the European Union's 27 Member States. Yet I fear that the Geographic Information community - or communities, for there are many - continue to… More…
