Abstract

Eelgrass is vital to coastal and marine health. Recognizing and understanding the significance of eelgrass die-offs in San Juan County is essential to identifying potential causes. Eelgrass beds provide habitats for many commercial costal fish and represent immense economic and ecological value. This document details a Web GIS application developed to help monitor the environmental condition of eelgrass and perform data management and spatial analysis in the San Juan Islands with the collaboration of scholars from the University of Redlands. A File Geodatabase was built to store the client’s data and then a web GIS application was developed using the ArcGIS API for JavaScript. The application was customized to enable the client to add new sampling sites, types of measurements, sampling values, view and query records, and visualize data using Esri’s Heat Map Renderer from the JavaScript API.
