Conclusion11 th International Symposium for GIS and Computer Cartography for Coastal Zones ManagementA toolbox workshop held November 2012 highlighted the need for a tool to clearly guide users through all themany parts of the Ocean Health Index. From the application’s Path panel, users will be able to drill down from theIndex to a goal (e.g. Coastal Protection) to a dimension (e.g. Pressures) to a component (e.g. Mangroves) to a layer(e.g. oceanic mangrove extent per region). Upon clicking the layer a popup will present all the stressor weights bypressure layer. It will also present backlinks to other goal dimensions for which this layer is used and a link to theLayers panel. Once in the Layers panel, the user can view the selected layer as a map, histogram or table as well asmodify or replace the table input. This type of interactivity transparently exposes all the elements and specific inputsof this complex framework. The additional Workflow Tools and Programming Interfaces further empower the advanceduser to easily explore any number of ocean resource management scenarios.Two regionalized efforts for Brazil and California Current (in submission) have already demonstrated the applicabilityof the framework at a more feasible spatial scale for practical management. An additional case study forthe even smaller Puget Sound is underway. The global index will be updated for 2013 at which point we will beginto show changes in the index over time. Most of the pressures layers are being updated as well. Certainly thistoolbox will facilitate the calculation, exploration and modification of the Ocean Health Index for these studies aswell as hopefully many more to come.AcknowledgementsConservation International funded tool development. Ocean Health Index team members Courtney Scarborough,Catherine Longo, Steve Katona, Deb Zeyen and Tina Lee have contributed significantly to the impetus, discussionsand workshop. Past developers of the Cumulative Impacts work, Shaun Walbridge and Matt Perry, have shareduseful code. For user interface advice and specific Javascript libraries, thanks to SeaSketch members Chad Burt andWill McClintock. Much appreciation goes out to the countless contributors of open-source software and publiclyavailable datasets, without which this project would be entirely impossible.ReferencesHalpern, B.S., C.
