Hazus Independent Tools

Comprehensive Data Management System

CDMS provides Hazus users with the ability to update baseline inventory datasets with local information, which increases the accuracy of a risk assessment in Hazus. Inventory data can be stored at the building level or aggregated across census blocks or tracks for more generalized analysis. CDMS helps ensure updated data imported into Hazus is formatted correctly for risk analysis, and it allows users to query, sort, and export inventory information.

When users download Hazus software, CDMS is automatically downloaded and installed. For more information, watch the CDMS training videos:

Hazus Open Source Tools

The Hazus program provides  open source tools designed for a variety of risk analysis tasks and  available on the Hazus GitHub page. These tools are simple to use and do not require coding experience. However, they arey developed using HazPy, the Hazus Python Package, which can be customized and extended by users with python coding experience to create new tools. Users can notify the Hazus Team about issues or enhancement suggestions for specific tools directly from GitHub by logging a GitHub issue or by emailing the Hazus Team.
