 Save the Date for the Fall Meeting

Grid to Ground 
for Mapping Professionals

Let's talk about points, the grid, and the ground.  Why not? 

As you are likely aware, progressively more high-precision GPS/GNSS (global positioning system/global satellite navigation system) based real-time-kinematic methods are being used in for project related mapping.

Unless proper correction methods are used, horizontal distances between two locations determined by the GNSS method will differ from the measurements that are made by traditional survey methods. This difference between the two measurements is often referred to as the grid-to-ground problem. This meeting will provide methodologies to address this challenge,  and assist the GIS community in gaining a better understanding of the process.  

When:  Tuesday October 6, 2015

Where:  New Jersey Institute of Technology- Newark, NJ

Time:  8:00 am- 3:30 pm
