Surveying and Mapping, Geospatial Awareness, and Bathymetry are critical components to ensuring project success from the start.  These key disciplines have been a basis of human development since the beginning of recorded history.  By using the art and science of these techniques, TCG’s team of licensed professionals can determine your project’s critical three-dimensional positions and points wherever they are on earth, air, or water.

After all, if you don’t have strong understanding of where you are, how can you know the direction you are headed towards?
