Port of San Francisco Bay Control, CA
Due to ongoing daily surveys conducted by eTrac in the Bay Area, our surveyors are continually collecting data for multiple clients in different areas. For surveying the same geographical location but in micro environments it is beneficial to have a local set of control points that can be easily accessed by eTrac personal and referenced to one another. To update existing Port of San Francisco control, eTrac installed 10 new benchmarks from pier 80 north to San Francisco Marina North. All benchmarks can be accessed by water for local project control and are referenced to different global datums as well for fluidity. This established control is used for daily surveys by the company surveyors using our small vessels in the area.
