ODMAP Program

The Overdose Detection Mapping Application Program (ODMAP) is a free, web-based tool that provides near real-time suspected overdose surveillance data across jurisdictions to support public safety and public health efforts in mobilizing an immediate response to a sudden increase or spike in overdose events. For over eight years, ODMAP has been available to government (state, local, federal, or tribal) agencies serving the interests of public safety and health. Each agency wishing to participate signs a participation agreement designed to protect the data within the system. Once signed up, they can begin uploading data and have access to the National Map feature, which allows users to view nationwide data and built-in analytical tools (i.e., filters, pre-built charts, and the ability to add additional data layers).

Approved users will also have access to several built-in features that aim to support agencies efforts, including, but not limited to:

• Spike alerts – Spike alerts send email notifications to a subscriber list when a designated area meets or exceeds a certain number of overdose events within a rolling 24-hour period. Spike alerts are available at the county level or using the custom geography feature. Users can also see where spike alerts are in effect across the country using the current and recent (within the last seven days) layers.
- • Spike Alert Video
- • Spike Response Framework – A tool for agencies to use when setting up their spike response, including information on how to integrate ODMAP into their response efforts.

• Custom Shapes and Bookmarks – These features allow users to create their own custom geographic boundaries and save them for future use or for triggering spike alerts.
- • Custom Shapes and Bookmark Video

• Add your own data – Users can layer additional data sets onto ODMAP, including their own data, to better understand spatial relationships or add additional data using Esri’s Living Atlas.
- • Adding Your Own Data

• Naloxone Saturation Layer (NSL) – Partners across the country share data on the number of publicly available naloxone kits, which are visualized based on the ODMAP naloxone saturation data definition.
- • NSL Webinar
- • NSL One Pager

• Tribal Nations layer – This new feature allows users to filter data by reservations, similar to how you can filter by states or counties. A built-in layer displays the various reservation boundaries on the map.
- • Tribal Nations Layer One Pager

Currently, over 5,300 agencies in all 50 states, the District of Columbia, and Puerto Rico are utilizing the tool. As of April 2025, nearly 3 million overdose events have been entered. Approximately 35 states and the District of Columbia have a statewide ODMAP implementation strategy, including 25 states with a statewide Application Programming Interface (API) to push data directly from their state systems to ODMAP.
