Dictionary:Convergence

{{#category_index:C|convergence}} 1. The condition when calculated values approach finite-limiting values as the number of terms or iterations used increases. 2. In iterative operations, such as modeling, the condition when calculated values become sufficiently close to observed values. 3. The effect of computing a survey on a curved surface as if the surface were plane. Applying convergence correction changes from assumed rectangular coordinates to geodetic coordinates.
