Solving a Localization
Before you can start collecting data in a conventional survey,
you must establish the location of the instrument and orient
the setup to your coordinate grid. If you setup on a known
point, you need to backsight one additional point in order to
orient the setup. Alternatively, if you setup on a new
unknown point, you need to solve a resection from multiple
control points in order to calculate the location of the
instrument and then orient the setup.
