EcoDat 2.0 is a custom application built using AGOL and Survey 123 to collect critical natural resource data in Vermont to be used for project design and environmental permitting purposes. The application uses a hybrid ArcGIS Collector and Survey 123 process to facilitate data collection. The application runs on the Collector Classic app on smart devices, typically iPad or Samsung android tablets paired with Trimble R1 GPS for sub-meter accuracy. The application is used on a daily basis by VHB ecologists during the field season to delineate natural resource features including wetlands, streams, vernal pools, protected plants, invasive plants and many other features. This presentation will detail how the application was built, how if functions in the field and the advantages that this data collection method offers.
