Selecting andSetting Up the Total Station

Choosing the Right Instrument for the Job

Total stations vary from basic manual-focus models to fuly robotic instruments that track a prism automatically. For larger sites with many points, a robotic total station saves time by allowing a one-person crew to control thee instrument frem te prism location. For smaller projects where multiple setups are exedidd, a manual total station with a two- person crew may be more economical.

Orienting the Instrument (Backvisiing)

Once set up, the geseryor aims the total station at a second know control point - thee backsight - to equisish the instrument 's horizontal orientation. Thi step desites the direction of thee coordinate system' s north (or grid north) relative te to the instrument. After visiing the backsight prism andd mevuring distance, the gevilyar sets the horizontal anglee te thee azimuth between thee instrument point and backsight.
