Track: Land Management
Author(s): David Grainger, David Grainger

There are numerous adjustment techniques, but least-squares adjustment (LSA) is the most precise and most commonly used in adjusting GPS data. Least squares adjustment in NILS is used to manage the measurement network, where it attempts to distribute errors within a survey network. By weighting inputs with a relative accuracy, the points and measures are adjusted to reflect a better fit in the survey network. The NILS Network Adjustment application consists of other tools to display misclosures of traverses, as well as to detect blunders that will give the user an idea about the survey network displayed.
