Many of the products we purchase by weight or volume are measured out using a certified scale or device. Consider the lunch meat you purchase at the delicatessen, did you notice a seal on the scale? How about when you buy gasoline? Have you noticed the seal on the gas pump? These measuring devices are certified by the state to assure consumers that they are getting exactly what they are paying for.  The measured quantities of weight or volume can be traced back to National Standard units.

It is curious that the single most expensive thing a consumer will ever purchase, their home, can be measured out without any guarantee that the measuring device used to determine the location of their corners or the area of their property meets any measurement standard at all.

Electronic Distance Measuring Instruments (EDMI) are one of the most common measuring tools utilized by land surveyors around the world. In some states, certifying their accuracy is required by law. In many foreign countries this is also required.

This webinar will examine what an EDM Calibration Baseline is and how they may be used to increase your confidence in your measurements.
