Join us for a seminar on Datum & Mapping Projections in Georgia. Presented by Mr. Lonnie Sears, LS and proudly hosted by Gwinnett County Government.
Presentation Description – Datum & Mapping Projections in Georgia
The National Geodetic Survey (NGS) through NOAA publishes datum information and map projection information for use in the USA and in various other countries around the world. In this seminar I will give a history of commonly used datum in the past and explain the current horizontal and vertical datum used by the NGS and all federal agencies. These are Horizontal – NAD83(2011), and Vertical – NAVD88 (geoid2012A) Many references will be given directly from the NGS web site www.ngs.noaa.gov where the National Spatial Reference System is fully described and facilitated. Questions and class participation will be greatly encouraged as we talk through this confusing topic.
