• Description:
  The TRAV10 adjustment program is the major tool for the adjustment of horizontal survey networks at the National Geodetic Survey. It performs a two-dimensional adjustment on the ellipsoid. Many features are similar to those of other programs used by other agencies. The handling of the normal equations, especially for large networks, is the most important design criterion. The TRAV10 program uses the Cholesky solution method with a variable band storage scheme. The normal equations are partitioned into variable sized blocks, stored on random access secondary storage, and paged into main memory as needed. A reordering of the unknowns is used to reduce both the required storage and the number of arithmetic operations.
