Overdose Detection
Mapping Application Program

ODMAP provides near real-time suspected overdose data across jurisdictions to support public safety and public health efforts to mobilize an immediate response to a sudden increase, or spike, in overdose events. ODMAP links first responders and relevant record management systems to a mapping tool to track overdoses to stimulate real-time response and strategic analysis across jurisdictions.

ODMAP was developed and is managed by the Washington/Baltimore HIDTA. Click here to learn more about the w/B HIDTA.

Each agency wishing to use the system will sign a participation agreement, which is designed to protect the data within the system. Once signed, they can begin uploading data in near real-time through a variety of methodologies. They can also get access to the National Map, which allows select users to view nationwide data and create custom visualizations. ODMAP is only available to government (federal, state, local, or tribal) agencies serving the interests of public safety and public health.

An Epidemic

Provisional data released from the Centers for Disease Control and Prevention's National Center for Health Statistics shows there was an estimated 107,622 deaths related to drug overdose in the United States in 2021. This represents an approximate 15% increase in fatal overdoses from 2020 involving different types of opioids and stimulants. However, there is an absent methodology nationally to track non-fatal overdoses. ODMAP offers the ability to collect both suspected fatal and non-fatal overdoses, in near real time, across jurisdictions, to mobilize a cohesive and collaborative response.

ODMAP Implementation Examples

Detailed below are examples of how agencies are implementing ODMAP within their communities to better combat the opioid epidemic.

How It Works


ODMAP is a web interface which can be accessed from any device and through a CAD system. The system is designed to minimize the effort and time required by a first responder to enter data. It will report date and time when accessed, and if the user accesses ODMAP in the field, the system will default to the GPS coordinates of the device for the location, or they can enter an address. The user must record whether or not the overdose incident is fatal or non-fatal and the extent to which naloxone or an overdose reversal drug was administered, in all taking seconds and provides the Level 1 user a confirmation when entered.


An Application Programming Interface (API) is a popular method for stakeholder agencies to contribute data without creating additional (manual) reporting or processes. The API allows for data integration by connecting with the agency or state's Record Management Software (RMS) to ODMAP. An API allows for the direct, automated integration of the two systems.

ODMAP connects to diverse fields such as EMS, Law Enforcement, and Health. EMS has adopted the National Emergency Medical Services Information Systems (NEMSIS). Law Enforcement does not have an industry adopted standard similar to NEMSIS, although, there have been attempts at utilizing the National Information Exchange Model (NIEM) standards, it is not implemented nationally. As a result, ODMAP developed a custom API which is simple to consume across disciplines.

ODMAP utilizes a REST API, combined with a JSON payload to transfer data between both systems. This is a combination of modern technology that is developer friendly and compatible with nearly all programming languages. Once an Agency identifies the data in their RMS, it takes approximately 2-3 weeks to implement the API.


ODMAP data is controlled unclassified information (CUI) and may only be released to authorized personnel. Recipients of this information must have a need and right to know the information in the performance of their criminal justice and public health functions. The National Map is designed as a tool for decision-makers to be able to view and analyze the data, nationwide, submitted to ODMAP. Per the ODMAP Teaming Agreement, ODMAP shall only be used for its intended purposes.

Spike Alerts

ODMAP is a system designed to provide vital information to relevant stakeholders in real time. Spike alerts can be set-up to notify an agency by email, if the total overdoses in an area exceeds a pre-determined threshold within a 24-hour period. Spike alerts can be established for an agency's own county, as well as nearby or neighboring counties. By establishing spike alerts for nearby counties, the program can serve as an early warning feature; if a spike in overdoses occurs in a neighboring area, officials can anticipate a spike in their area and prepare.

In order to support the needs of our community, the W/B HIDTA public health analysts developed a Spike Response Framework which is designed to provide guidelines and promising practices, from peers across the country, in working through an overdose spike.

The figure below displays how ODMAP can be utilized to rapidly respond to spikes in overdoses.

ODMAP Data Entry

ODMAP Data Entry Interface

The ODMAP Data Entry interface allows participating agencies to upload, in near real-time, suspected drug overdoses from anywhere in the country. With our Application Programming Interface (API), we are also able to receive data from agencies via a direct upload from their systems.


National Map Interface

The National Map allows participating agencies to view the collected data suspected drug overdoses data, in near real-time, from anywhere in the country. Users are able to filter the data, overlay additional information, and create customs visualizations.


Spike Alerts

Agencies are able to create Spike Alerts in Level 1 based on a either a recommended threshold generated by the system or using a number of there own choosing. These alerts can be sent to emails specified by the agency and when a spike does occur, it is tracked by the system and will appear in the Spike Alert History when it is over. Agencies can also create Spike Alerts for an entire state, allowing them to be notified if a spike occurs in any of the participating counties for that state. There is also that ability to create alerts for when an overdose has been entered into the system, based on state, coutnty, and incident type.
