For a lot survey, which instrument combination is permitted?

For a lot survey, you have flexibility in the instrument you use. An Electronic Total Station (ETS) combines precise angle and distance measurement on site, which works well in a controlled, local network with known points. On the other hand, GNSS determines positions using satellite signals, which is efficient for establishing coordinates over larger areas or where access to lines of sight is limited. Both methods can meet the required accuracy when done correctly, with proper data processing and adherence to standards. Because either method can satisfy the survey requirements depending on site conditions, control availability, and accuracy needs, the permitted option is using either ETS or GNSS.
