How to Get Started

Viewing public assessments and downloading datasets do not require creating an account.

If you already have a user account, please login or if you wish to register, you can create an account. An account will allow you to contribute to new or existing health assessments.If you are new to HAWC, the following tutorials will guide you through a step-by-step process from creating an account, getting started and how to use HAWC in different types of extractions, data cleansing, evaluation and visualization of information.
