It’s now possible to obtain decimeter (10cm/4in) horizontal and vertical accuracy using a mapping-grade receiver! This
presentation will cover the techniques and equipment necessary to achieve this level of accuracy. Such accuracy can be
obtained in the field or back in the office after data collection. Decimeter-level accuracy addresses the area in between
the survey-grade and the traditional “submeter” where GIS accuracy is typically defined. It is now possible to map
locations and navigate to underground facilities, critical infrastructure, and utility features when decimeter accuracy is
appropriate. Learn about the progress of Wisconsin DOT’s network of reference stations which will bring high-accuracy
possibilities as well as high-productivity GNSS to all of the state once completed. The status of the network construction
will also be addressed.
