SeaSketch is a decision support tool that supports collaborative map-based design workflows – putting science and information at the center of participatory processes. SeaSketch empowers all participants to engage directly with GIS tools – exploring mapped data, expressing and analyzing their plan ideas, and more. Over the past five years, SeaSketch has been used in dozens of projects all around the world – ranging from comprehensive marine spatial planning processes to community-driven conservation planning processes to facilitating collaboration between remote teams of scientists planning for data acquisition and vetting existing data sets. All of these projects have had unique needs, and the tool developers from the McClintock Lab at UC Santa Barbara have updated and adapted the tool to meet these needs and support these processes. This webinar will give participants an overview of the SeaSketch platform, share exciting new feature additions that have been implemented to strengthen collaboration between remote teams, and highlight the resources tool developers provide so users can get the most out of their SeaSketch project.
