It is the mission of the Elevation Technical Working Group (ETWG) to do all those things necessary to coordinate the LiDAR Data Collection efforts for all entities involved in the State of Georgia. By doing so we will help control the cost, insure the quality and return the best value for terrain data for all the interests in our State.  We will support all those interests which require terrain data for their decision making and we will educate and train all parties interested as to the importance of this data.
