Wengler Surveying & Mapping employs highly qualified and trained staff using
advanced equipment and technologies.

Traditional field data is measured using a TOPCON GTS 211D Total Station, which
is an instrument that combines horizontal and vertical angular measurements with
an electronic distance meter. The measured data is collected and stored
electronically using a Tripod Data Systems (TDS) RECON brand data collector.

Global Positioning System (GPS) measurements are made using TRIMBLE 4600LS
Geodetic grade receivers.

Both traditional and GPS measurements are adjusted by a rigorous least squares
adjustment process using STARNET software employing the latest geoid and
vertical deflection models.

Maps are drafted with AutoCad and plotted using a Hewlett Packard Designjet
large format plotter.

We host our own web server that contains our web page and a comprehensive
database of over 12,500 survey images dating back to 1864.
