203 – Grid and Ground 101
Background: Using today’s technology we sometimes need to combine GPS derived “Grid” coordinates with conventional total station “Ground” coordinates.
Course Goals & Objectives: We will examine how Trimble Business Center and Trimble Access software distinguishes between grid and ground coordinates, how to compute a scale factors for conversion between the two and how to represent your survey data.
Prerequisites: Some basic level of survey knowledge will be required for this course. The user should also have some knowledge of how GPS and Total Station measurements are made. After completing this module you may want to consider course "209 - GPS Site Calibrations".
Approximate Duration: 2 hours
