The Survey 1-2-3 data collection app is an app that uses on-line formatted forms for data collection. This app does not directly update to a map, instead the data is collected into a data layer that is hosted in the HWS cloud instance of ArcOnline and Survey 1-2-3.

Survey 1-2-3 is a tool designed to collect data using a formatted form environment. The location is then recorded as data is collected when the form is submitted.

Getting Started: Accessing Survey 1-2-3 through your ArcOnline Account and setting up a Survey form.

To get started with this tool, you first need to have an active account within the HWS ArcOnline portal site.
The HWS ArcOnline Portal Site: https://hws.maps.arcgis.com/
Once you have access to ArcOnline (and have logged in), you can then use Survey 1-2-3.

Survey 1-2-3 will have your username in the upper right hand corner (that was pulled from your login to ArcOnline). In the middle of the screen, click on 'My Surveys'.
On the 'My Surveys' screen, click on the 'Create a New Survey'
