Result Interpretation

WGS84-to-UTM18N affine bias correction computes easting_utm18n_corrected in m and northing_utm18n_corrected in m using the defined engineering formula and the input values provided. easting_utm18n_corrected is expressed in m; northing_utm18n_corrected is expressed in m. No universal acceptance threshold is defined by this calculator.

Worked Example

default_test

Given:

  • e_gps = 500000
  • e_utm = 500000

Expected Result:

  • easting_utm18n_corrected = 0
  • northing_utm18n_corrected = 0

Engineering Interpretation:

Under the given input conditions, the calculated result is: easting_utm18n_corrected = 0 m; northing_utm18n_corrected = 0 m.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from deterministically validated test cases.

Formula / Method
