New Spatial Tools Available to Assist Coastal Managers with Mapping and Analysis
Four new ArcGIS tools, initially developed for ongoing National Centers for Coastal Ocean Science projects, have been made available to the geographic information system (GIS) user community through the ESRI website. These tools were originally developed for specialized tasks, but have been enhanced for wider use. Two quality assurance/quality control tools, Adjacent Features and Overlapping Features, were created for the Hawaiian Benthic Habitat Mapping project, enabling a user to quickly locate overlapping polygon and adjacent polygons sharing the same attributes. An analytical tool, the Diversity Calculator, was developed to calculate species richness, Simpson’s Index of Diversity and Shannon ‘s Diversity Index values for the Caribbean Coral Reef Ecosystem Monitoring project. A processing tool was developed for the 2008 State of Coral Reef Ecosystems report to read in point data and create line segments with the points’ attributes.
