What is SALSA?

Welcome to the project page for the Surveyor’s Applications for Least Squares Adjustment, or SALSA. SALSA is a feature-rich rigorous 3-D geodetic least squares adjustment software package developed by Applied Research Laboratories, The University of Texas at Austin. We are excited to make SALSA available to the global community of surveyors, geodesists, and anyone who has an interest in optimally combining spatial measurements using weighted least squares. For more info, take a look at this brief introduction, or check out the User Manual.
