Abstract In the past the adjustment of geodetic networks was traditionaly done in sectiong the technique of condition equations. In order to obtain the adjusted parameters and their variance covariance matrix from this method,they must be computed as explicit functions of the adjuted obser vations and variance covariance matrix. Such a procedure ususally eniarges the computations and time for obtaining the adjusted parameters consequentiy the variance covariance matrix was not to the computed because it needs to store the variance covariance matrix of adjusted obser vations which needs a huge part of the computer menory this is one of the disadvantages of the conditional adjustment . Accordinglyanother method ofadjustment can beused. Such a method is usually called parametric methodane it is very suitable for use with an electronic computer hence. this thesis is directed towards deveioping a computer program package cabable of dealing with theproblem of readjusting the geodetic networks.In order to minmizes the storage used . The normal equations are partitionedinto varible sized blocks and a reordering of the unknowns is used to reduce both the reqired storage and the number of arithmatic operations . These problems can be used on a main frame or a personal computer. |
