Computation ProcedureThe computation procedureautomatically defines the calculationmethod, e.g. 2 point resection,3 point resection withangles only, etc…).If more than the minimumrequired measurements areperformed, the processing routineuses a least squares adjustmentto determine the plan position andaverages orientation and heights.1. The original averaged face Iand face II measurementsenter the computation process.In case of multiplemeasurements to the sametarget point, only the lastmeasurement for each faceenter the computation process.2. All measurements are treatedwith the same accuracy,whether these are measured insingle or dual face.3. The final plan position (E, N) iscomputed from a least squaresadjustment, including standarddeviations and residuals for Hzangleand horizontal distances.4. The height of the station (H)including the standard deviationand residual is calculated fromthe averaged heights (based onthe original measurements).5. The Hz-circle orientation iscomputed with the originalaveraged face I and face IImeasurements and the finalcomputed plan position.53
