TerraViz is continually investing our time and other resources in remaining at the forefront of GPS technology. GPS surveys are the preferred method of controlling projects that require a standard that is compatible with gps driven equipment on a construction project. GPS surveys, in general, are far more accurate than conventional surveys depending on the methodology used to obtain the desired information. Sub-centimeter accuracy is possible relative to the client’s specifications. Statements made in this paragraph are understood to be taken as relative and project specifics will dictate accuracy.
