LEAST SQUARES ADJUSTMENT

In Landonline, least squares adjustment is used for the following purposes:

• Adjustment of geodetic control and generation of geodetic coordinates. This is essentially the same as before Landonline, with least squares being a standard geodetic tool.
• Automated validation of cadastral surveys. Automated adjustments are run which check the internal accuracy of the survey, how well it fits any SDC coordinates, and the strength of the survey network. The reports from these adjustments are available to surveyors via the pre-validation reports.
• Manual validation of cadastral surveys. LINZ staff may investigate further if the automated validation adjustments require clarification.
  Network adjustments of approved cadastral surveys and other survey data to integrate the new survey into the network, generate authoritative coordinates and orders and assign these coordinates SDC status where they meet the accuracy standards.
