What happens if I move this console four feet to the right? How is performance affected if I switch this operator with that one? These are the questions that the Spatial Analysis Link Tool (SALT) was developed to answer. For years SALT has assisted Human Factors professionals in creating, modeling, visualizing, analyzing, and optimizing spaces.
SALT was developed for the Naval Surface Warfare Center in Dahlgren, Virginia, built on open source technologies, using open standards, and provides a reliable platform on which to conduct spatial analysis.
A simple SALT workflow allows the user to import an image of a space (from Visio, CAD, or even PowerPoint...any standard graphics format is accepted), place people and equipment into a space, and define the relationships and interactions between them. Interactions between and among people and equipment can be viewed and analyzed. The health of each interaction (or link) is displayed immediately to the user as he or she moves elements around the screen. At a glance, a user can see which links are strained or even broken.
