The User selects the number of the nearest common control Points to be used for each Point to be transformed.

The Search Limit to be used when the programme is requested to search for the nearest group of Stations to the current point.

The type of Weighting required (None, Inverse Distance or Inverse Distance Squared).

The User selects settings from a number of offered options, namely :

Due to the nature of the re-adjustment of the Hartebeesthoek94 co-ordinates using a transformation based on a table of adjustments, or parameters, for a given area cannot provide the same level of accuracy as that of a Weighted Helmert transformation that uses the 4 or 5 closest common Control Points lying around to the Point being transformed.

This programme should not, therefore, be confused with other programmes that offer only approximate (0.50m – 1.50m) transformations for the purpose of small scale mapping, or non-survey related activities.

Accuracies in high density urban areas tend to be higher, due to the larger number of common Points in these areas. Tests have shown that typical Standard Deviations resulting from transformations vary between 0.01m and 0.07m.Where we have a large number of common control Points (38,000) the transformations are extremely localized and provide the highest accuracy of transformation possible between the two Ellipsoids. This programme is designed to satisfy the requirements of Land Surveyors, Mine Surveyors and Engineering Surveyors requiring high accuracy transformations (The transformation carried out is by using either a Weighted Helmert transformation, or a Standard (non-weighted) Helmert transformation, with a User determined number of common control Points.These data may be contained in a SURPAC Co-ordinate file, an ASCII Co-ordinate file, an ASCII file or be written data that are to be entered manually. To carry out a transformation, it is only necessary to have co-ordinate, or Geographical, data related to one of the two Ellipsoids, and lying within the geographical boundaries of the specific country.In other countries, we have attempted to have as many Control Points as we can lay our hands on. In South Africa, for example, two control files are provided that cover the entire country and which contain approximately 38,000 common Control Points.Zone System) and the Hartebeesthoek94 Datum (WGS 84 Ellipsoid) (either an RSA “WG” System, or a U.T.M. This programme provides for rapid and accurate transformations between the Cape Datum (Clarke 1880 Modified Ellipsoid) (either an RSA “Lo” System, or a U.T.M.Zone to Transverse Mercator (or ) System transformations Transverse Mercator (or ) System to U.T.M.Transverse Mercator (or ) System 1 to System 2 (Belt 1 to Belt 2) transformations.
