Mapping Accountability: A Geospatial Approach to Combating Fraud, Waste, and Abuse
Fraud, waste, and abuse aren’t just financial problems—they’re operational threats that undermine public trust and divert critical resources from communities that need them most. Whether it’s a fraudulent disaster aid claim, a phantom health-care facility, or an inflated invoice for services never rendered, bad actors are getting smarter.
Every fraudulent claim, misused payment, or misrepresented facility happens somewhere. That “where” is the missing link traditional tools often overlook. GIS fills that gap—visualizing patterns, uncovering relationships, and validating claims with objective, geospatial evidence.
This technical paper introduces a practical, location-driven approach to identifying and reducing fraud across various mission areas, including health care, public works, emergency management, and social services.
Inside the Paper:
– Detecting clusters of suspicious activity using spatial analytics and AI – Mapping provider, patient, or vendor patterns that defy logic – Integrating drone and satellite imagery to verify claims – Revealing hidden relationships through network and link analysis – Streamlining investigations with shared dashboards and secure collaboration
By embedding location intelligence into your oversight workflows, you not only gain visibility—you gain momentum.
A Platform Built for Accountability
GIS isn’t just a mapping tool—it’s a platform for insight, integration, and action. Most agencies already use Esri technology for planning, infrastructure, or emergency response. This paper demonstrates how these same tools can be configured to support investigators, auditors, and compliance teams—without requiring the need to reinvent the system.
From collecting whistleblower tips to analyzing impossible billing patterns, GIS helps agencies do more with less—and do it smarter.
If your mission is to protect public dollars, promote transparency, or modernize oversight, this guide is for you.
