A new Collector app is available on iOS. For help with the new app, see Prepare your layer.
Follow this series of exercises to create and share a damage assessment map to use in Collector. You'll start by creating a data model, defining the look of your data, and publishing your data model as a layer in the first exercise. The second exercise walks you through creating a map, including setting up the data collection form, and making the map available to workers in your organization.
