Introduction

The GHOST software library includes a number of programs used in the adjustment of control survey data as well as programs required to adjust the data using the Helmert block method of subdividing the network. There are a number of utility programs that can be used to process the data as well or perhaps some associated tasks. The data are stored in ASCII files for input, some binary files during the adjustment process and listing files for evaluation and of the results. MapInfo® files can be written to display the coordinates and observations.

Original User Documentation

The original GHOST User Documentation (with revisions) is also available in hypertext format. It provides some more details on using GHOST. Eventually, all of the information in this original documentation will be combined with this hypertext version. Until then it is recommended to have a look at the original version, especially if you are new to GHOST.

Main Programs

Adjustment steps: Run program GHOST or follow separate program steps below

READCC Define adjustment constants
EDTPOS Edit GHOST coordinates
EDTOBS Edit GHOST observations
PERMIN Compute minimum profile for normal equations
ADJCLA Normal equation reduction, inversion and solution
LISRES List adjustment results and perform confidence region analysis

Program VALDEK (validate GHOST records) may be used in place of programs READCC and EDTPOS if the BLKCORD and INTCOBS files are combined into a single data file. This method is not used anymore. See the Section 1.2 of the old GHOST documentation for more information.
